23N Rebid by Opener3N_Rebid_by_Opener.btn 3NT Rebid by Opener After opening one of a suit, opener can jump to 3NT two very different ways (TWB #635): 1) Partner has NOT shown a good hand - a long, solid suit with outside values. e.g. 1!H-1NT-3NT on a solid 6-card major (18-20), or 1!m-...-3NT on a solid 7-card minor with an outside A/K. 2) Partner HAS shown a good hand (a game-forcing 2-over-1) - extra values with stoppers in the unbid suits. e.g. 1!H-2!D-3NT (15-17). A 2NT rebid instead would show a balanced 18-19; the 3NT jump is about a source of tricks (a running suit) or stoppers, not just points. https://www.advinbridge.com/this-week-in-bridge/635 4NT is Roman Keycard Blackwood (0314) with a trump suit agreed, or quantitative (inviting 6NT) in a notrump auction. Keycard responses: • 5!C = 0 or 3 keycards • 5!D = 1 or 4 • 5!H = 2 without the trump queen • 5!S = 2 with the trump queen365007.2%
3Help Suit GTHelp_Suit_Game_Try.btn Help Suit Game Try After 1M - Pass - 2M, opener bids a new suit showing 3-4 cards with about one top honor, asking responder for help in that suit. Responder bids game with useful holdings (void, singleton, Ax, Kx, etc.) or signs off with poor holdings (xxx, xxxx). https://www.bridgebum.com/help_suit_game_try.php495009.8%
4Snapdragon DoubleSnapdragon_Double.btn Snapdragon Double After LHO opens, partner overcalls, and RHO bids a new suit, a Snapdragon double is artifical and forcing. It shows 5+ cards in the lone unbid suit, at least 8 HCP, and a tolerance for partner's suit. 'Tolerance' ranges from 2 to 3 cards. https://www.bridgebum.com/snapdragon_double.php5550011.0%
5Double double...Double_double.btn Double, double toil and trouble... After x (y), X is a Negative Double. It's for takeout. At the 1-level it promises 4-Cards in each unbid major. At higher levels you need a backup plan if partner doesn't have your major -- maybe a tolerance for opener's suit. If you double again, it's a scrambling takeout double.6150012.2%
6Scrambling 2NTScrambling_2NT.btn Scrambling 2NT. In a competitive auction, when your'e forced to bid, 2NT is Scrambling. Two NT in competition may be Good/Bad or Scrambling.

1Bust Over Strong 2CBust_Over_Strong_2C.btn Responding to a Strong 2C with a Bust Partner opens a game-forcing 2!C (22+ HCP) and you hold a near-worthless hand: 3-1-3-6 with only the !SJ and the !CT, 1 HCP and no other honors. Even opposite 22+ the partnership is rarely making game, but 2!C is forcing to at least 3 of a major (or game), so you cannot pass. Bid the waiting 2!D, then make your second negative on the next round to warn partner the hand is dead. https://www.bridgebum.com/strong_2c.php5

3After Partner's Takeout XAfter_Partner_Takeout_Double.btn Advancing Partner's Takeout Double West opens 1!C, 1!D, 1!H, or 1!S. Your partner (North) makes a takeout double, and East passes. You — the advancer — must respond. You are NOT allowed to pass a takeout double for penalty here; partner is asking you to bid, so describe your hand. Two jobs as advancer: bid your longest suit, and show your strength by the LEVEL you choose, not by bidding longer. • 0-8 HCP — bid your longest unbid suit as cheaply as possible. • 8-11 HCP — JUMP in your longest suit (the jump shows values, not length). • 12+ HCP — cuebid opener's suit, forcing to game. With a stopper in opener's suit you may bid notrump instead of a suit: • 1NT — 8-11 HCP with a stopper. • 2NT — 12-13 HCP with a stopper. • 3NT — 14 HCP with a stopper. Partner (the doubler) then shows any extra by raising your suit (4-card support) or cuebidding opener's suit (only 3-card support but extra values). Level: intermediate.

4Responsive DoubleResponsive_Double.btn Responsive Double LHO Opens, Partner Doubles, RHO raises, and you make Responsive Double, showing both majors if LHO opened a minor, otherwise, the other major and 3+ cards in each minor. 4NT is Roman Keycard Blackwood (0314) with a trump suit agreed, or quantitative (inviting 6NT) in a notrump auction. Keycard responses: • 5!C = 0 or 3 keycards • 5!D = 1 or 4 • 5!H = 2 without the trump queen • 5!S = 2 with the trump queen2026-01-302026-07-27
5Spiral Raises WolpertSpiral_Raises_Wolpert.btn Spiral Raises Wolpert Opener may raise responder's major to 2M on 3- OR 4-card support. Responder then asks with the cheapest step, and opener spirals out support length, strength, and shortness. (Wolpert: Spiral Raises.) After 1!D 1!H 2!H, responder asks with 2!S. Opener answers: - 2N 3-card support, balanced, minimum - 3!C 4-card support, balanced - 3!D 3-card support, short in the other minor (!C) - 3!H 3-card support, short in the other major (!S) - 3!S 4-card support, splinter in !S - 3N 3-card support, balanced, maximum - 4!C 4-card support, splinter in the other minor (!C) - 4!D 5-4-2-2, maximum - 4!H 5-4-2-2, minimum (5-4-2-2 means five in the opened minor with four-card support.) After 1m 1!S 2!S the ask is 2N, the same scheme shifted up a step. A 1!C opening mirrors 1!D with the minors swapped. https://bridgewinners.com/article/view/spiral-raises/ 4NT is Roman Keycard Blackwood (1430) with a trump suit agreed, or quantitative (inviting 6NT) in a notrump auction. Keycard responses: • 5!C = 1 or 4 keycards • 5!D = 0 or 3 • 5!H = 2 without the trump queen • 5!S = 2 with the trump queen2026-06-152026-07-25
6Basic NT RespGIB_1N_Basic.btn Basic Notrump Responses A Basic 1NT shows a balanced hand (4333, 4432, 5332, or maybe 5422) w/15-17 HCP and no 5-card major or 15-16 with a 5-card major. Basic Responses include Stayman, Jacoby Transfer, and 2/3 Notrump.2026-04-102026-07-22
7Basic Weak 2Basic_Weak_2.btn Basic Weak Two-Bid (beginner) South opens 2!D, 2!H, or 2!S as a weak preempt. A weak two-bid shows: • 6-card suit (exactly 6 cards — not 5, not 7) • 5-10 HCP • 2 of the top 3 honors in the suit, or 3 of the top 5 (good suit quality) • Limited side-suit values (no 4-card major outside, no 4+-card minor with values) Partner's responses: • Pass — happy to play 2-of-suit with a weak hand • 2NT — strong inquiry asking for shape and strength (Ogust or feature ask) • 3-of-suit — to play, with 3+ support and weakish hand • 4-of-major — to play, often preemptive • New suit — strong, forcing For beginners: open weak 2 with disciplined hands. The 6-card suit is the preempt's whole structure. Don't preempt with poor suits — partner will sometimes raise to game on a fit, and you need to deliver tricks. Reference: https://www.bridgebum.com/weak_two.php 4NT is Blackwood, asking for aces, or quantitative (inviting 6NT) after a natural notrump bid. Responses: • 5!C = 0 or 4 aces • 5!D = 1 ace • 5!H = 2 aces • 5!S = 3 aces • 5NT then asks for kings the same way2026-05-142026-07-21
81N w/Bal Raise1N_Balanced_Raise.btn 1NT Balanced Raise (no four- or five-card major) Partner opens 1NT (15-17). You are balanced with no four-card or five-card major, so there is no Stayman bid and no transfer to make -- you raise notrump straight to the level your points call for. Pass with 0-7, invite game with 2NT on 8-9, and bid game with 3NT on 10-15. With slam values keep bidding notrump: 4NT is a quantitative slam invitation on about 16-17, and with 18-19 bid 6NT to play. Opener passes a minimum over your 2NT or 4NT and accepts with a maximum. A pure point-count decision: add your points to partner's 15-17 and pick the level.2026-07-182026-07-18
93-card Limit Raise (11-12 TP) 1N/3MGavin_3-Card_Limit_Raise.btn 3-Card Limit Raise (1!H/1!S - 1NT - 3!H/3!S) Partner opens 1!H or 1!S and you hold invitational values (about 11-12 total points) with exactly three-card support. You are too good for a simple raise, but you cannot jump to three of the major directly -- a direct limit raise promises four trumps. So start with a forcing 1NT; after partner rebids a suit, jump to three of opener's major. That delayed jump shows the invitational raise on just three trumps, letting opener judge game: accept with extra values, pass a minimum. https://tinyurl.com/4dvh42e72026-01-302026-07-18
10Open w/Rebid in MindOpen_and_Rebid.btn Basic: Open the Suit That Buys You a Rebid (beginner) Usually you open your longest suit. But first ask: after I open, what will I REBID? When you are minimum (about 11-15) you cannot introduce a higher-ranking second suit at the two level -- that shows extra strength you do not have. So when opening your long suit leaves you no cheap rebid, open a DIFFERENT suit instead. • 5 clubs and 4 diamonds: open 1!D, not 1!C. Over partner's major you rebid 2!C, showing both minors. Open 1!C and your only way to show diamonds is 2!D -- a higher-ranking suit at the two level, promising more than you have. • 6 of a minor and 5 of a major (6!C-5!H, 6!C-5!S, 6!D-5!H, 6!D-5!S): open the 5-card MAJOR, then rebid your long minor cheaply. Open the 6-card minor and showing the major means bidding it at the two level -- higher-ranking, more than you have. • Both minors 5-5: open the higher, 1!D, then rebid 2!C. Sometimes the ordinary rule already works: with 5 diamonds and 4 clubs, open your longest, 1!D, and 2!C is cheap anyway. The skill is spotting when opening your longest suit would leave you stuck.

GIB splinters with a singleton A, K, or Q. Some players do NOT. • After 1!C a jump to 3!D, 3!H, or 3!S • After 1!D a jump to 3!H, 3!S, or 4!C6m19s

After the opponents open and partner's weak jump overcal is doubled... responder has six possible continuations: • Bid game - Preempt or Rule of 17 • Raise below game - a mild preempt • Bid a new suit - Please lead this suit. • Bid 2N - I'm interested in game. Do you have a feature? • Redouble - I have a long suit of my own • Pass - Good Luck!1m17s
8Rabbi's RuleRabbis_Rule.btn Rabbi's Rule — safety play, drop the singleton King "When the King is singleton offside, play the Ace." This is a SAFETY PLAY. South opens 1!S and partnership reaches 4!S. Declarer has 10 sure tricks WITHOUT touching the diamond Queen — solid trumps, the heart Ace, and a club winner — but the diamond suit is the trap. • AQxxx in declarer opposite xxx in dummy. The King is missing. • West has the SINGLETON K. East has Jxxx. • Take the safety play: cash the Ace. The stiff K drops; the Q is established as a small bonus, but more importantly you never give up the lead. Contract makes. • Try for an overtrick by finessing: lead toward the AQ and play the Q. West's K wins. Now West can put East in, and East cashes long hearts. Contract goes down — at least 1, sometimes more. The lesson: COUNT your top tricks before deciding any finesse. If you already have enough to make, the finesse is gratuitous risk — and Rabbi's Rule (cash the Ace) is the safer play. Things to think about: • What's your trick count BEFORE you touch diamonds? • Where is the danger hand for cashing — east or west? • Does the auction (silent opps) say anything about diamond distribution?1m16s

Choice of FinessesChoice_Of_Finesses.btn Choice of Finesses (3NT) South opens 1NT (15-17 balanced), North raises to 3NT, South declares. West leads a heart. Teaching feature: declarer has ONE heart stopper (the Ace) and TWO finesses available, in spades and clubs. WEST — the opening leader — has a 5-card heart suit headed by KQ. After holding up the Ace to exhaust EAST of hearts, the choice of finesse decides the contract: • Clubs — Axx in South, KJx in North. Lead small from South toward dummy's KJ. If it loses, EAST wins — and East has no hearts left. ← SAFE. • Spades — KJx in South, Axx in North. Lead small from dummy toward South's KJ. If it loses, WEST wins — and West cashes the long hearts. ← FATAL. The decision: • Duck hearts until East is out (West leads them; East has only 2-3). • Then take the CLUB finesse — it loses safely to East. • Do NOT take the SPADE finesse — it hands the lead to West, the danger hand, who cashes the established hearts.

Endplay / StripEndplay_3rd_Round_Strip.btn Strip-and-Endplay (4!S) South opens 1!S, partnership reaches 4!S. Teaching feature: declarer faces a critical loser problem in one side suit (typically clubs). Rather than finessing for the Q, declarer can STRIP the other suits, then throw East in with a heart and force East to lead into declarer's club tenace. Holdings: • Spades — 5-3 fit with solid honors. • Hearts — declarer has AKx (or similar) opposite small; can play two rounds to exhaust East, then throw the third round to East. • Diamonds — declarer cashes A and K, ruffs the third in dummy if needed. • Clubs — AJx opposite Kxx, with the Q missing. The 50% finesse can be avoided entirely by the endplay. The plan: 1. Win the opening lead. 2. Draw two rounds of trump (don't draw all — you may need a trump entry). 3. Cash AK of diamonds; ruff the third diamond in dummy. 4. Cash AK of hearts. 5. Lead a third heart to East. 6. East must return either a club (into your AJ tenace — J wins) or give you a ruff-and-discard. Either way, you don't lose a club trick. Things to think about: • Why do you NOT take the club finesse? • What if East has shorter clubs than expected? • How do you keep the trumps you need to recover from each ruff?

Finesse - SimpleFinesse_Simple.btn Simple Finesse (3NT, 4!H, or 4!S by South) South opens with a 5+-card major and the partnership reaches a major game or 3NT. South declares. Teaching feature: South holds an AQ in a SIDE suit without the K. The K is in East or West, roughly half the time each way. • When South opens 1!S, the finesse suit is ♥ (AQ-no-K). • When South opens 1!H, the finesse suit is ♠ (AQ-no-K). • 5-3-3-2 hands sometimes open 1NT and play 3NT — finesse still applies. To take the finesse: lead small from dummy toward South's hand and play the Q if East follows small. The Q wins about half the time. Things to think about: • Count winners and losers first. • When in the play should you take the finesse? • If the finesse loses, where else can you make tricks? • Did the auction or the opening lead hint where the K sits?

Fit-Jumps after 1M (X)Fit_Jumps_after_1M_Double.btn Fit-Jumps after 1M - (X) Partner opens 1H or 1S, your right-hand opponent makes a takeout double, and you have a fit for partner plus a good second suit. A jump shift in a new suit is a FIT-SHOWING JUMP, showing in one bid: . 4+ card support for partner's major . a 5-card side suit with at least one top-3 honor (a real source of tricks) . limit-raise-or-better values (about 10-12 support points) Auctions (north opens 1M, east doubles for takeout): . 1H - (X) - 2S / 3C / 3D — fit jump: 4+ hearts + a good 5-card spades / clubs / diamonds . 1S - (X) - 3C / 3D / 3H — fit jump: 4+ spades + a good 5-card clubs / diamonds / hearts Why jump instead of redouble or a simple raise? The double crowds the auction, so one descriptive bid is worth a lot. Showing the fit AND where your side values live lets opener judge the double fit, spot wasted honors, and decide how high to compete or whether to bid game/slam. Opener then evaluates: . fitting honors opposite your side suit -> push to game or slam . wasted honors opposite your side suit -> compete only, or stop in the major . minimum with no side fit -> sign off in the trump suit https://www.advinbridge.com/this-week-in-bridge/574500203297 0.0s 0.0s 34.0s 0.0s 5.1s 0.1s 0.0s 0.1s 0.0s 0.0s 39.4s

So this scenario covers 1m openings only. Opener evaluates the double-fit potential: . fitting honors in the side suit -> push to game or slam . wasted honors in the side suit -> stay at 4m or settle low . minimum opener with no side-suit fit -> pass or settle in trump suit https://www.advinbridge.com/this-week-in-bridge/574500104396 0.0s 0.0s 13.0s 0.0s 5.0s 0.1s 0.0s 0.0s 0.0s 0.0s 18.2s

Found EndplayFound_Endplay.btn Found Endplays (4!H / 4!S) — curated strip-and-endplay candidates These hands are scanned from all bba/*.pbn files by [find_endplay_candidates.py]: South declares a 4-of-major contract, and declarer's side holds an AJ tenace in one side suit (with East likely holding the Q) plus solid honors (AK or AKQ) in another side suit so a strip is feasible. The teaching pattern: strip the side suits where you have winners, then throw East in (typically with a heart or club) and force East to lead into your tenace. This converts a 50% finesse into a 100% endplay. Things to think about: • Count your losers; if a finesse can be avoided, look for a throw-in. • Strip the safe exits BEFORE the throw-in. Once East is in, every lead helps you. • The thrown-in opponent should be the one holding the Q of your tenace suit.

Each hand demonstrates Rabbi's Rule — "When the King is singleton, play the Ace." West holds the singleton !D K. East holds the !H KQ threat. To make 4!S, declarer must drop West's bare K rather than finesse for it. Things to think about: • Count your tricks before touching the trump suit. • If you have 10 top tricks on the safety play, take them — don't finesse for an 11th and risk going down. • The safety play here is dropping the singleton King.

Hold-Up at 3NTHold_Up_3N.btn Hold-Up at 3NT (duck to sever the defenders' long suit) South opens 1NT (15-17 balanced), North raises to 3NT. Teaching feature: declarer has exactly ONE stopper in hearts (the Ace). WEST — the opening leader — has a 5-card heart suit headed by KQ and leads it. East has only 2-3 hearts but holds the side-suit entry declarer must knock out. If declarer wins the first heart, then knocks out East's entry, East still has a heart to return and West cashes the long suit — 3NT goes down. The hold-up technique: refuse to win the early heart tricks. Duck until EAST (the hand with the entry) is OUT of hearts, then win the Ace. Now when declarer drives out East's entry, East has no heart to return — West's established hearts are stranded with no way back in. Things to think about: • How many times should you duck? Just enough to exhaust East's hearts. • After ducking, where will you take your remaining tricks? • Lose the lead only to East (safe once they are out of hearts); keep West, with the long suit and no entry, off lead.

Inverted minors merely reverse these responses. After an inverted raise to 2, opener should show both majors stopped by bidding 2N. With only one stopped, bid the stopped suit.

Open w/Rebid in MindOpen_and_Rebid.btn Basic: Open the Suit That Buys You a Rebid (beginner) Usually you open your longest suit. But first ask: after I open, what will I REBID? When you are minimum (about 11-15) you cannot introduce a higher-ranking second suit at the two level -- that shows extra strength you do not have. So when opening your long suit leaves you no cheap rebid, open a DIFFERENT suit instead. • 5 clubs and 4 diamonds: open 1!D, not 1!C. Over partner's major you rebid 2!C, showing both minors. Open 1!C and your only way to show diamonds is 2!D -- a higher-ranking suit at the two level, promising more than you have. • 6 of a minor and 5 of a major (6!C-5!H, 6!C-5!S, 6!D-5!H, 6!D-5!S): open the 5-card MAJOR, then rebid your long minor cheaply. Open the 6-card minor and showing the major means bidding it at the two level -- higher-ranking, more than you have. • Both minors 5-5: open the higher, 1!D, then rebid 2!C. Sometimes the ordinary rule already works: with 5 diamonds and 4 clubs, open your longest, 1!D, and 2!C is cheap anyway. The skill is spotting when opening your longest suit would leave you stuck.

One call shows the whole hand. • Four-card support for partner's suit: raise. Two of the suit shows a minimum; a jump to three shows about 16-18 and invites game. • A six-card suit and no fit: rebid your suit. Cheaply (the two level) shows a minimum; a jump (the three level) shows extra and invites. • A second four-card suit you can show at the ONE level: bid it. A new suit up the line needs no extra strength. The level of the rebid is the message: the cheapest call shows a minimum, a jump shows about 16-18 and asks partner to think about game.50042377 0.0s 0.0s 0.6s 0.0s 4.9s 0.1s 0.0s 0.0s 0.0s 0.0s 5.7s

NT openings are excluded — the topTricksNS=8 constraint counts tricks in suit-contract terms. Teaching feature: declarer has enough TOP tricks (sure winners) to make 8 tricks for the contract. The lesson is COUNT FIRST, CASH SECOND — don't get fancy with finesses or unnecessary risks when you already have the tricks you need. Things to think about: • Count your AKs and trump length tricks before leading anything. • If you have 8 top tricks, take them. Don't risk for overtricks unless it's free. • If you're short of 8 top tricks, then find the ones you're missing — but THIS scenario is designed so you have enough already. • Watch for entry problems: order your plays so each hand can lead when needed.

Rabbi's RuleRabbis_Rule.btn Rabbi's Rule — safety play, drop the singleton King "When the King is singleton offside, play the Ace." This is a SAFETY PLAY. South opens 1!S and partnership reaches 4!S. Declarer has 10 sure tricks WITHOUT touching the diamond Queen — solid trumps, the heart Ace, and a club winner — but the diamond suit is the trap. • AQxxx in declarer opposite xxx in dummy. The King is missing. • West has the SINGLETON K. East has Jxxx. • Take the safety play: cash the Ace. The stiff K drops; the Q is established as a small bonus, but more importantly you never give up the lead. Contract makes. • Try for an overtrick by finessing: lead toward the AQ and play the Q. West's K wins. Now West can put East in, and East cashes long hearts. Contract goes down — at least 1, sometimes more. The lesson: COUNT your top tricks before deciding any finesse. If you already have enough to make, the finesse is gratuitous risk — and Rabbi's Rule (cash the Ace) is the safer play. Things to think about: • What's your trick count BEFORE you touch diamonds? • Where is the danger hand for cashing — east or west? • Does the auction (silent opps) say anything about diamond distribution?500209291 0.0s 0.0s 1m11s 0.0s 4.5s 0.1s 0.0s 0.0s 0.0s 0.0s 1m16s

Ruff Before TrumpSide_Suit_Ruff_Before_Trump.btn Side-Suit Ruff BEFORE Drawing Trumps (4!S) South opens 1!S, partnership reaches 4!S, South declares. Teaching feature: declarer has 5 spades opposite 3 in dummy. Dummy has a SINGLETON heart. Declarer's hand has 3+ small hearts (one or more losers). You need to ruff a heart in dummy — but you must do it BEFORE drawing trumps, otherwise dummy's trumps will be gone. Holdings: • Spades — AK + 3 small in South opposite Jxx or Qxx in dummy. 5-3 fit. • Hearts — singleton in dummy, several losers in declarer's hand. The ruff is the only way to dispose of one of declarer's heart losers. • Diamonds/clubs — split honors. If you cash AK of trumps first, dummy's small trumps go away. Now you can no longer ruff hearts in dummy. The lesson: WIN THE OPENING LEAD, then take your heart ruff IMMEDIATELY, then return to drawing trumps. Things to think about: • Count your losers and trumps before touching them. • Plan the order of plays before leading to trick 2. • If trumps split 3-2 it's safe to draw one round before ruffing — but never more.500335165 0.0s 0.0s 0.6s 0.0s 4.6s 0.1s 0.0s 0.0s 0.0s 0.0s 5.3s

Opponents hold the AKQ. By repeatedly leading the suit and forcing out the top honors, the J and T eventually become winners. Holdings: • Spades — declarer's main suit (often AKQ in a 5-card holding). • A side suit — JT9x in North opposite xx or xxx in South. Lead toward the JT9 until A, K, Q have been driven out. Then J and T are winners. The trick: • You must have ENTRIES to dummy after the high cards are flushed. • Count: after 3 rounds of the suit, only J, T, 9, and any small cards remain. Your J wins on the 4th round. Things to think about: • How many losses are you willing to accept in this suit to build winners? • Where are your entries to dummy? • Sometimes a defender's discard signals their stoppers.

To Finesse or Not?To_Finesse_Or_Not_To_Finesse.btn To Finesse or Not To Finesse (4!S) South opens with a strong spade hand and the partnership reaches 4!S. Teaching feature: COUNT YOUR TRICKS FIRST. Declarer has so many sure tricks (typically 10-11 without help) that the contract is already there. A finesse is available in clubs, but it has NO UPSIDE — you don't need the trick — and a real downside if it loses. Don't take a finesse you don't need. Holdings: • Spades — AKQJT in South, x or xx in dummy. Solid trump suit. • Hearts — A in South, small in dummy. One control. • Diamonds — split honors. Two or three tricks. • Clubs — A and J on declarer's side, K opposite. The Queen is missing; the finesse is for an overtrick only. The right line: count to ten. If the contract is cold on top tricks and ruffs, draw trumps and claim — there is nothing to gain from the club finesse and a needless risk in giving up the lead. (East holds long hearts, but in a trump contract that is at most one cashing trick before you ruff — the point is not the heart danger, it's that the finesse simply isn't needed.)

Top Tricks (NT)Play_Top_Tricks_NT.btn Top Tricks — Notrump Contract (beginner) 1NT — Pass — 3NT — all pass. Final contract is 3NT (declarer needs 9 tricks). Teaching feature: NS holds all 4 aces (in either hand) AND exactly 9 quick tricks on top. We assume outside entries exist, so split chains DO count (e.g., AK opposite Qxx = 3 QT). The per-suit count is capped by the longer single-hand length in that suit (so AK opposite Qx = 2 QT, since no hand has 3 cards in the suit). Responder is constrained to no 4-card major (so no Stayman) and no 5-card major (so no transfer). The auction stays natural 1NT—3NT. Things to think about: • Count your top tricks before touching the hand. • Chain rule: A, then K (anywhere in NS), then Q, then J, then T. • Length cap: split chains need length in the longer hand to materialize.

Wins if East has the Q. • Lead low from South toward dummy's KT, finesse the T. Wins if West has the Q. The challenge is deciding which way to commit. Things to think about: • Did the auction give either defender a chance to show shape or strength? • What did the opening lead suggest about distribution? • Watch early tricks for count signals or revealed lengths. • Vacant places: if one defender has shown more of the other suits, the Q is more likely with the other defender. • With no information at all, it's 50/50 — pick a side and commit.

Your first job is to keep the bidding alive and start describing your hand. • A fit for partner's major: raise. 3-card support and 6-9 is a single raise to the two level; about 10-12 with support jumps to the three level to invite game. • A new suit you can show at the ONE level: bid it (going "up the line" to the cheapest four-card suit). A new suit is forcing -- partner must bid again. • No fit and nothing to bid at the one level: respond 1NT, showing about 6-10 and denying support or a cheap new suit. • A good five-card suit and about 10+ points: you can introduce it at the two level, which promises more than a one-level response.
