East opens 1H; a few Souths may overcall 1S but this is well below the standard for a vulnerable overcall. I've seen players simply jump straight to 4H with a hand like West's but that is defined as a preemptive or "shape" raise: five trumps, a singleton or void, and perhaps six to nine high card points. My preference is to define the response of 3NT as a "pancake raise", 13 to 15 high card points and any 4333 (but poor slam controls if the four is in trumps.) Most club players treat a jump to 3NT over either a major or minor as "to play", but this treatment appears to be virtually non-existent among experts -- 16 to 17 or 18 is the usual standard, or some sort of raise. With 3244 shape, there may be slam in either minor and the normal procedure is to start with a 2/1 bid, game-forcing or not. You can always bid 3NT later.

At any rate, a hand with only three card support is not suitable for Jacoby -- the fourth trump can be crucial for slam bidding. Some pairs playing 1NT forcing (in response to a major) may bid 1NT followed by 4H to show the flat raise, but experience has shown that it is a bad idea to mix game-forcing hands in with 1NT: when the auction turns competitive or opener makes an unexpected jump, you can't describe your values properly. Lacking an agreed raise, West responds 2C, planning to support hearts later. East rebids 2D, whether or not 2C was game-forcing. In the modern style the 2/1 bidder promises a rebid, at least over any new suit by opener; jumping with East's hand will often lead to missing the best strain. (I define opener's jump to 3D here as 5-5 with about 15+ hcp.) Now responder supports hearts: 3H playing Standard, or 2H in a go-slow style of 2/1 game force. Many pairs play "fast arrival" and would leap to 4H with West's hand, but this throws away much of the advantage of playing sound or game-forcing 2/1 bids: West has useful slam controls (two key cards, and control of diamonds) and should want to leave room in case partner has slam interest. The sequence 2C-then-4H should describe a hand with good cards in clubs and hearts and no control of the side suits.

As it happens East is strong enough to proceed directly with 4NT, so any sequence that shows West's game values and support should suffice. West replies one Ace or two key cards and East signs off at 6S or perhaps tries for a matchpoint top at 6NT. Slam requires no more than the expected 3-2 heart split, although 6NT from West's side may fail on a spade lead. This is a possible disadvantage of my recommended 3NT "pancake raise" (or 1NT forcing) but North may not have any clear reason to lead a spade rather than a club. Still, I suspect East will prefer 6H to protect his King if partner bid notrump first.

South faces a common lead problem: cash the Ace (which risks setting up declarer's King for his twelfth trick) or punt (which risks seeing declarer rattle off thirteen winners.) The usual advice is to cash an Ace against a suit slam (or 7NT!) but not against 6NT or seven of a suit (expecting one opponent or the other to be void.) Here, however, East is a heavy favorite to hold the King of spades. The defense will still score a trick if North does not pitch a club.

Only three of nine pairs bid slam, a bit puzzling since by simple point count East's hand counts as 19 or 20 and West has an obvious 13. Perhaps 1H-4H-pass was all too common.

South is on the bubble for a 1H opening. Those who insist on 12 hcp will pass without a second thought; Rule of 20 fans will count 11 hcp plus nine cards in their two long suits and open breezily. I tend to use the old Goren short-suit count with a reluctance to count both high cards and shortages in the same suit. This is simply a way to account for the fact that, in a trump contract, hands generally play better when the points are concentrated in the long rather than the short suits. Counting one point for the diamond doubleton but not the spade is the same as saying : "this hand is borderline and my suits, especially hearts, aren't all that good." I would probably pass this one but would certainly open if the hearts were K1098x.

West has a fine suit and should open or overcall either 1S or 2S. This is a point below either a Rule of 20 or Goren 13 count, so I would open 2S if South passes. It's plenty strong enough for a 1S overcall, but tactically I prefer the jump. Of course I'd make the same bid without either side Queen.

North bids diamonds regardless of what South and West do, planning to support hearts later if South opened. If South passed originally he can bid 2H or 3H as needed. East may get in the act, however; with four trumps he may compete to 3S or 4S, but the hand is too weak and shapeless for my taste. On defense N/S should collect two hearts, a diamond and three clubs; declarer can reach dummy with a heart ruff and guess whether to play South for the King or Jack of spades. So 4S doubled is on a guess between -500 and -800, an iffy bet at matchpoints. N/S should score at least +650 at 5H. If West opened or overcalled 1S, declarer may play him for both Queens, scoring an overtrick. After a 2S opening or overcall, declarer is more likely to finesse East for the Queen of clubs after West shows up with the AQ of spades and the Queen of hearts.

West has an iffy hand for a vulnerable weak 2D, but A1097 gives the suit some body and it's tempting to preempt both majors. If you like this sort of bid I recommend playing Ogust responses to partner's 2NT inquiry so you can warn partner "bad suit, bad hand." Assuming a prudent pass, North opens 1S or 1NT. With precisely 16 hcp I recommend straining to open 1NT on hand with no more than one doubleton. The only exception should be a hand with a five card major and a small doubleton --North's Qx is apt to be more valuable at notrump than in a suit contract, if partner has a fitting honor or the opening lead is away from AKxxx. Why the emphasis on 16 hcp? With 15, you can treat the hand as a minimm (12-14.) With 17 you can stretch for a 2NT rebid (nominally 18-19 over a one level response, but often only 17 after a major suit opening.) But with 16 any notrump rebid will mistate your values by a full Queen. Meanwhile, if you open the major, partner will often raise and you are too strong to pass. When partner rejects your game try, you may find yourself down one at 3S rather than +90 at 1NT. One other consideration -- with three hearts, you'll be OK if partner transfers to hearts. Some players avoid opening 1NT with precisely 5233 or 2533 since you may play a 5-2 major fit instead of 5-3.

East passes, too weak for a vulnerable overcall or jump. Over 1NT, South contemplates slam in clubs or notrump. At 3 points per trick it's reasonable to expect opener's 15-17 to cover at least five of South's six losers. Visualizing, thirteen tricks would be a near laydown opposite Axx Axx AQxxx Jx. This looks like a reasonable hand for the rare Gerber convention: 1NT-4C; 4S (remember, that's two Aces!)-6NT. East may well lead a major, with a heart yielding twelve tricks or a spade resulting in thirteen. While hearts would be the normal lead against 3NT, I would not lead away from that holding against 6NT. On a minor suit lead declarer should knock out the Ace of diamonds and cash two major suit high cards before taking the rest of his minor suit winners. If no one pitches the "promoted" King or Queen, finesse in the other suit. Unfortunately it looks better to cash the two high spades (hoping to drop the Queen) and 6NT should ultimately fail on the heart finesse. C'est la Bridge!

Everyone played this one at 3NT.

West opens 2C, planning a 2NT rebid after the expected 2D response (or 2H bust.) East adds 13 + 22 = 35 and should certainly drive the hand to 6NT. Possible sequences:
(1) 2C-2D (negative, waiting or semi-positive); 2NT-6NT
Or East might try 3S if that's Minor Suit Stayman; West rebids 3NT, denying a minor, and East raises to six.
(2) 2C-3NT; 6NT
If East could bid 2NT to show a balanced 8-10, 3NT shows 11-12.
(3) 2C-3NT; 4NT-6NT
If 2NT would be a heart positive (playing 2H = bust), 3NT shows 10-12. West shows a bare 22 but East has extras.
(2) 2C-2NT (Steps, 10+ hcp)-3NT; 6NT
West's 3NT is probably a dead minimum since 23+10 would be 33.

North should not lead away from his King (the defense needs two tricks, not five, so "fourth from your longest and strongest" doesn't apply.) A minor suit lead hands declarer his twelfth trick. If North (or South) guesses to lead a heart, declarer needs to develop two tricks. Three finesses are available (either way in the minors), or you can try for a 3-3 split in either minor. You can also cash two winners in either minor before finessing against North.

All in all it looks right to run the Jack of spades early, since you have no choice whom to finesse. Assuming North exits with another heart, declarer can get gather clues by careful cashing. Take the third high heart and then cash three winners in either minor, ending with the Ace in East's hand. When North shows out, cash the two high spades. The Ten-Nine might drop; as it is, South must discard a minor, after which his Jack will fall. Six of nine declarers failed, perhaps trying for two of three finesses or delaying the spade finesse until it was too late to squeeze South.

South is a bit shy of an opening bid. One of my partners used to add a point for the spade suit, but Richard Pavlicek has documented that this is a losing strategy -- better to wait and overcall later. North opens 1H; East shows both minors by leaping to 2NT (Unsusual.) The good spots make this reasonable even at unfavorable vulnerability, at matchpoints anyway. South can bid a cautious 3H, or an aggressive 4H; that risks hanging partner for opening light in third seat. A fourth trump would make that more reasonable.

An expert treatment here is "Unusual Over Unusual", where a simple bid of 3H or 3S is competitive, while a 3C bid (their lower ranking suit) shows a good hand for hearts (our lower ranking suit) and 3D shows a good hand for spades. With that agreement South bids 3C (preferring the known fit to showing spades.) West knows his side has a double fit but he covers only one of partner's losers, and that with an Ace which may be just as useful on defense. Doubling 3C ought to ask for a club lead; as it happens a 3D call might get partner off to a better lead.

North has more than enough for 4H. Should North think about slam? Partner is a passed hand and North has two Queens in East's minors -- seems like game is enough. If West bids 4C and East tries five, South should pass the decision back to North. North has fine defense but with a known 10 card fit 5H looks safer and that should end the bidding.

South opens 1C; North responds 1H or a strong jump to 2H. South raises hearts. North might hunt for a club control but it's hard to imagine South having an opening bid with no control there so 4NT seems obvious. When South shows only one Ace (or key card) North may as well take a shot at the matchpoint contract of 6NT -- with 21 hcp opposite an opening bid that should work. Nine pairs bid 6H, one grabbed a top at 6NT and two missed the slam. Declarer pulls trumps (if any), knocks out the Ace of clubs and claims.

North opens 1C; South has a fine jump to 2D if you play that as a strong but flexible bid (does not promise five card length, does not deny a side suit.) This enlists opener's cooperation in hunting for slam. North doesn't care much for hearts as a trump suit for slam; 2NT looks like a good rebid here. South continues with 3C, effectively showing a 16+ point raise. North can expect South to cover five or so of his six losers, so slam looks reasonable. North bids 3S, which may be a control bid or a notrump probe -- North has not shown any extra values yet. South bids 3NT but North reveals his slam interest by pulling to 4C. Now South control-bids 4H, North bids 4NT (Blackwood or Key Card), South replies 5H. If that's Blackwood North continues with 5NT, South bids 6H to show two Kings and North ends the bidding at 6NT. Playing Key card North would know over 5H that a key card is missing and will sign off at 6C or 6NT.

Most Souths will not jump shift, either playing that as weak or requiring five card length. A 1D response is forcing; North rebids 1H. Now what? In most partnerships 3C would be invitational, not forcing; South must resort to the Fourth Suit gadget. In Bridge World Standard, 1S is always natural, so South jumps to 2S to show an artificial game force. This tends to ask for a spade stopper and North is happy to bid 2NT. Now South can bid 3C, showing doubt that 3NT is the right spot -- either South is too shapely or has slam interest (as here.) Either way North has a good hand for slam and 6C at least should be reached.

Another approach would be an inverted minor raise by South; North shows his spade guard, South continues with 3D, North bids 3NT (suggesting a holding like this, length but not much strength in hearts.) But now South may pass 3NT rather than jeopardize the game contract.

Lastly, N/S may play that jump rebids by responder are forcing: 1C-1D; 1H-3C, forcing. But South does not promise more than enough for game and again the bidding may stop at 3NT. I think this slam is far easier to reach with a simple 1C-2D strong jump.

North has a routine "Goren 13" or "Rule of 20" opening bid, complete with the two quick tricks recommended for minimum openings. With an easy 1S rebid over the expected heart response, 1D will be a popular choice. East overcalls 1S or opens 1S if North passes. South has barely enough for a 2C response; the Jack of spades is of doubtful value but the partial fit for opener is encouraging. Note that "2/1 Game Force" does not apply in competition. If North passes, South has a poor hand for a 2C overcall -- bad shape, a poor suit for the two level (KQ10xx or KQxxxx would be a typical minimum) and that questionable Jack. Nevertheless many Souths will overcall anyway. Can West double to show hearts? Most would interpret a double that way but the problem is that partner must bid something, probably rebidding spades. Then West must pass on what may be a 5-1 fit or climb up to 3H. A Weak Jump Shift In Competition (3H) would get to the same level quickly. With a singleton in partner's suit it will often be better to pass -- perhaps partner can reopen with a double. North raises to 3C and West either sits for that or back in with 3H. The length in clubs and shortness in spades favors defending. On a spade lead the defense will likely collect two spades, a heart, diamond and club and perhaps a ruff, but the diamond may go away on the King of spades. Four hearts can be made by finessing in spades or by ruffing clubs if the defense fails to lead trumps.

Most of the field reached this odds-on slam. A reasonable auction might be 1H-2NT (Jacoby); 3NT (medium hand, about 14-15 hcp or mild extra shape)-4D (control bid); 4S-4NT; 5H-6H. The key here is that both North and South have some extras. Over the Jacoby raise, when opener does not show a singleton, 4H shows a minimum hand (no more than about 14 Goren points, high cards + distribution), 3H  shows a strong hand (16+ hcp, or about 17+ Goren points) and 3NT shows something in-between.

The slam depends on one of two finesses in the majors; both fail, about a 25% chance.

I expect most Norths opened 3C - I would. South suspects hearts may be a better strain, and even game may be possible, but bidding is likely to simply raise the level on a misfit. It would be nice for 3H to show this sort of hand, not forcing but worth a raise with support; but the usual rule is to play a new suit forcing in response to a preempt and in the long run I think that's best. 3C ought to end the bidding but some players can't stand to pass -- West may back in with 3S, raised by East and doubled by South for -300. Note that South should not consider bidding 3NT -- South can count only seven or eight tricks and partner's hand rates to be useless.

If North for some reason passes, South opens 1H, West may pas or stretch to overcall 1S and North thinks there may be game. With only three-card support, however, it will be difficult for South to set up and use the clubs. The ideal bid here is a passed hand jump shift, promising a fit for opener's suit: pass-1H; 3C. If north overcalls, I think the fit jump is apt to be more common and more useful than a "Weak Jump Shift In Competition" by a passed hand, that is, one that was not worth an original preempt. The fit jump will be enough for South to bid game without over-reaching for slam.

Repeat after me: "ALL JUMPS BY A PASSED HAND PROMISE A FIT FOR OPENER!" Along with that, a passed hand should never leap to game with only three-card support; there should be a cue-bid or Drury or passed-hand jump available for when you think you may have game. Keeping those rules in mind will help partner evaluate slam chances.

South opens 1S -- this isn't quite enough for 2C; if partner passses, you are probably not missing game. West, vulnerable, has no bid with his K empty seven-bagger. North must decide between inviting game and forcing. By point count the hands counts to 11 -- 10 hcp plus one for the doubleton diamond; don't count both the Jack of hearts and the doubleton. Losing Trick counters will count seven losers and force to game. The hand is too strong in terms of high cards and defensive tricks for a straight 4S raise, so the choice is between a forcing raise (such as Jacoby 2NT) or simply bidding 2D and then insuring game is reached. For slam purposes 2D and then 4S is a fairly good description, highlighting the source of tricks and letting opener decide if he has the controls and strength for slam. With the point count and LTC disagreeing, let's try visualizing: if we can construct a laydown game hand with only 10 hcp for partner, we should drive to game; if we need a perfect 12 or extreme shape, it's better to simply invite. So, partner might have, say, AKQxxx xxx xxx x, but a singleton opposite one of our doubletons seems unlikely. Perhaps AKxxxx Kxx xx xx : not totally a laydown but certainly  heavy favorite. well, if partner hates to pass game invitations, 3S looks right; if partner thinks you might have two or three points less than this, better force to game.

Assuming North bids 3S, South counts one or two spade losers, zero or one heart, two diamonds and a club -- call it five losers. A limit raise suggests 3.5 cover cards -- a bare three would be at the upper end of a simple raise while four full should force to game. (North's actual hand can expect to provide four or five winners but lacks the controls for a clear game force.) Slam looks iffy and I would settle for 4S over a limit raise. If North forces with a Jacoby 2NT, South bids 3S to show extra values (16+) and then drives the hand to slam since he has even more. Likewise South should push on if North follows the 2D-then-4S path.

Note to key card bidders: North/South are missing one key card plus the Queen, but with a 10 card fit two trump losers are unlikely. North's bidding may or may not clearly indicate four trumps. As it happens the spot cards would make slam a good bet regardless of the combined trump length, but it's always hard to diagnose AJ1098 unless all are in one hand. Three of five pairs reached slam.

South, in between the strength for 1NT and 2NT, opens 1C. North responds 1S and South shows 18-19 with a jump to 2NT. North adds 13 hcp and one or two for shape, so slam looks possible. At notrump there will be at most 32 hcp, so the best hope is that South has four clubs and/or five spades. Now North must be sure about the partnership style: would 3C be forcing or not? I recommend, and have seen various experts state, that after opener's jump to 2NT, any non-game bid is forcing; if we want to stop in a part-score, it can only be 2NT. This leaves maximum room to explore with good hands. On that basis North can bid 3C. South shows delayed (3-card) support with 3S. North control-bids 4H, highlighting the need for a diamond control. South has that covered and can proceed with 4NT, then bid slam after North shows two Aces or two key cards plus the Queen of trumps. Although 6NT also makes as it happens, South cannot be sure North's has quite so much in high cards and +980 should score well.

If opener might pass 3C, responder must jump to 4C (partner will surely have either three spades or four clubs) or use a gadget such as New Minor Forcing (if your partnership extends that to opener's 2NT rebid.) In either case opener shows delayed support for spades and responder can proceed toward 6S. Three of five pairs reached this good slam.

North opens 1NT; South counts a combined 29-31 hcp. South has seven losers and can expect North to cover 5 (3 points per trick.) So far, not quite enough for slam. Try visualizing: is there a perfect minimum that makes 12 tricks a laydown?  QJxxx Axx Axx Ax looks right. On that basis South has enough to invite but not force to slam. While you may not reach slam opposite that perfect minimum, the actual hands partner accepts will include the perfecto plus as well as hands with other extras that compensate for any flaws. Now, how to invite? If you haven't redefined jumps to the three level, 1NT-3D is forcing with at least five diamonds. Playing transfers, South can transfer to diamonds (2NT or 3C), followed by 3NT. This is a slam try; with no interest in slam responder should not bother showing a long minor on a hand with no singleton. North has a good fit and excellent controls; but does South control spades? North can control-bid 4C, South bids 4S, and North proceeds with 4NT. After the one Ace or 2+ Queen reply, North bids 5NT to confirm all four Aces or all five key cards plus the Queen. Playing Blackwood, South may reply 6H and North retreats to 6NT. This happens to make on the low-odds double-finesse in hearts. Playing Key Card, South bids 6D to show one side King and North passes. On a club lead declarer will still need the double finesse; on any other lead might have a chance to pitch two clubs if the first heart finesse failed. No one bid this thin slam and in fact +460 scored a top -- against North's 3NT, East certainly leads a club and North will be reluctant to risk even one finessse, let alone two.
