North opens 2H in third seat, catching East with a shapely 18 count. East starts with a takeout double; South should pass – the enemy have 24+ hcp and the 6-2 heart fit does not provide safety above the two level. West bids 3D. Playing lebensohl, this suggests 7-10 hcp; a weaker hand would start with 2NT. Not playing lebensohl, East must guess at West’s strength; adding his 18 to an average of 8 for North leaves 14 hcp outstanding, so playing West for about 7 hcp seems right. East counts roughly five losers (a spade, two diamonds and a club) and 7 hcp (probably not in hearts) should cover two; not enough for slam. However, South’s failure to raise suggests West may have four hearts; along with four diamonds that insures a ruffing value in one of the black suits. This is the sort of hand where bidding a slam seems aggressive but you shouldn’t be too surprised if it makes.

East continues with a 3H cue-bid to gain more infomration; West, with an efficient 1-point heart stopper bids 3NT, which should be the final contract. Declarer starts the diamonds with the King, playing the partner of the preemptor for a possible AJx; 10 tricks should be routine.

My partner chose to be optimistic; North led the King of hearts against 6D. Dummy’s Ace won perfoce and South covered the King of trumps with the Ace and of course North’s Jack was smothered. A ruffing finesse set up two heart tricks for a top. 3NT making four scored six out of nine.

East opens 1H and South leaps to 2NT, unusual for the minors. With a known 5-5 fit, five losers and excellent controls, West wants to be in slam as long as East has two useful key cards. Although standard advice is “don’t use Blackwood with a void” since you can’t be sure which Aces partner has, I figured that the enemy would not allow us a leisurely auction with their huge club fit. Some might simply blast 6H but I also reasoned that if partner had only one key card, he could not have the two I needed! Over my 4NT, North tried to gum up our bidding with 5C. DOPI to the rescue! It rarely comes up, but when someone bids over 4NT, the standard agreement is Double Zero Pass One (D0P1, or “dopey”.) With two or more key cards or Aces, partner bids up the line to show 2,3,4 or 5. Partner correctly bid 5D here and had no problems at 6H.

DOPI, by the way, is one reason I dislike the “1430” variant of key card asking – an online poll showed that half of those playing “1430” believed that, having agreed “DOPI”, they really meant “Double = first step, Pass = Second”, i.e., Double = 1 or 4, Pass = 0 or 3. I can see no great advantage in that agreement, but I wouldn’t call it DOPI; call it DFPS if you like. Or simply play straight up DOPI.

Side note: DEPO means “Double Even, Pass Odd”; this was Dorothy Truscott’s original gadget but is now commonly used when the enemy bids 5NT or higher, leaving no bid at the five level to show two. “ROPI” means Redouble Zero, Pass One; next time you think you can beat 4NT (i.e., you are on lead with a strong suit) try doubling to see if they get this right.

West opens with a heart preempt; applying the rule of 2, 3 and 4, 3H would be correct at equal vulnerability. However, with an 8 card suit and virtually no defense I would try 4H. Either way, North cannot really portray his 9 ½ trick hand. Can you think of a way to get partner to bid slam with the AQ of clubs and no spades? Over 3H, North can try 4NT and bid slam if partner shows an Ace. But over 4H, 4NT is more useful as a two-suited takeout bid, and North may simply take the near-certain plus at 4S. If North is allowed to use Blackwood, South’s two Aces and one King makes 7NT standout. Only one pair bid slam.

South opens 1C. With game-forcing values, North should respond 1D, planning to bid the spades next, whether or not the pair plays an up-the-line style. This pays off when South jump raises to 3D. North must now decide between 6D and (if South has help in hearts) 3NT. With 6 losers and the King of hearts as a plus value (it may be useful if partner has the Ace but not King of clubs and either the Ace or Queen of hearts) slam looks promising. Visualizing, South might have Ax xxx KQxx AKxxx, making slam a near laydown. An immediate 4NT (trusting partner to control the clubs) is probably the simplest approach, but this may a bit pushy. To invite slam, North can try 3S, an apparent notrump probe. South, with a heart stopper, bids 3NT; now, when North pulls that to 4D, his earlier 3S bid can be re-interpreted as a slam try. It woudl make no sense for North to explore for 3NT and then retreat to a part-score, so this should be a clear slam try, but be sure partner is on the same page before you try this!

South has an excellent hand for slam and cue-bids 4H; now North can reasonably proceed with 4NT. South replies with two Ace or three key cards; North bids 6D. (What about the Queen asking bid? Most variants of this will not allow stopping short of slam; I, personally, like to play that 5H asks and 5 of the agreed suit denies the Queen; when the asking bid is above the suit, as here, 5NT denies and North could pass that on this auction. But this does not appear to be a well-known variant.)

Against 6D East tries the Queen of hearts; North pulls trumps and collects two spades, a spade ruff, two hearts, six diamonds and a club. 6NT makes on the club finesse but only one pair bid slam so playing the safer 6D is clearly superior.

South has a normal 1H opening -- 11 hcp + 2 for a six card suit, open if the total is 13 or more. Although the AJ tight of spades is a flaw, the good intermediates (three tens, especially the ten of hearts) offsets that. Those who think they need 12 hcp for an opening bid will open 2H. North has a 21 point monster, 6 1/2 tricks plus length in two suits. 21+ 12 = 33, so North should drive to at least a small slam unless some fatal flaw is uncovered. North can start with 2C and plan to rebid in diamonds. South rebids 2H; many players assume this promises extra length but most experts treat opener's rebid as a default action, lacking the ability to bid anything more descriptive. In particular, either 2S or 3C normally shows extra values (15+ or so) and opener will not always be suitable for 2NT. (Those who play 2H promises six card length must rebid 2NT on lots of minimum hands with or without stoppers in the unbid suits.)

Over 2H, North continues as planned with 3D; a bedrock principle of standard bidding is that a new suit-over-suit bid by a responder who has never passed is 100% forcing. Think about this North hand next time you are tempted to pass such a bid! Here, South can repeat the hearts or, if 2H already promised six card length, bid 3NT since he has the spades stopped. The hearts are self-sufficient so rebidding hearts is reasonable in any case. Now North can be confident of a heart fit; ideally, he'd like to know if South has spades under control, but there aren't a lot of high cards around for South to have an opening bid without a high spade. Since any heart raise could be passed North bids 4NT, Blackwood or Roman Key Card. South replies 5D (one Ace) or 5S (two key cards plus the Queen of trumps.) North continues with 5NT, inviting grand slam; this bid confirms all the Aces or all five key cards plus the Queen of trumps. South may and usually does reply with something about Kings, but the crucial part is promising all the Aces or key cards.

South has a minimum so he replies 6D (one King) or 6C (no side Kings, the heart King being included among the key cards.) Blackwood bidders cannot be sure of the trump Queen and should simply bid 6H. Key-carders count a spade trick, six hearts, three diamonds and two clubs; if partner has the Queen or only two clubs there should be a good play for grand slam, but I wouldn't risk it. The last question is whether to bid 6NT (12 running tricks) or 6H (hoping to set up a 13th trick.) At a team game I'd pick the safer 6NT but at matchpoint pairs 6H gives you a good shot at an overtrick.

Against 6H West does not want to lead from an honor; I'd lead the four of diamonds (4th best.) South wins in dummy, plays the Ace and three more rounds of trumps, cashes the AK of clubs, hoping to ruff out the Queen. When West shows out, declarer lead the Jack of clubs, ruffs East's Queen and thereby promotes the nine of clubs as a 13th trick. The one declarer who tried 7H probably failed by taking the club finesse, only a 50% chance; setting up the clubs by ruffing is better than 80%.

Board 21: North opens 1NT (15-17) and South bids 2C, Stayman. This is normal when you have 5-4 or 6-4 in the majors: check on four-card support first. If opener does not have a major you can jump in your longer suit next (to game in this case, since you have six spades.) North replies 2S and now South's hand improves with the known 6-4 fit. South can count 6 losers and at about 3 points per trick, 15 hcp should cover 5 of those, so South is interested in slam. In most partnerships South would simply bid 4NT (Blackwood or keycard) followed by 6S; the values are a bit thin to consider grand slam.

One problem with treating 4NT as an asking bid is what would South do with something like AJx Kxxx Ax KJxx? With a combined 31 to 33 hcp, South would like to bid 4NT as a natural, quantitative slam invitation; how many Aces partner has won't tell you whether you have the 33 hcp for 6NT. Experts use a gadget here (3 other major slam try is one possibility) but that's a bit deep for newer players. Only one pair reached the excellent slam; at our table South began with a transfer, then bid game, never learning about the big 6-4 fit.

East, on lead against 6S after a Stayman sequence, tries the Queen of diamonds, hoping not to see K10x or A10x in dummy. Declarer grabs dummy's Ace, puls two rounds of trumps, and crossruffs clubs and hearts, watching for the King of clubs; when it comes down the Queen provides an overtrick.

East opens 1S; this hand lacks enough controls and sure tricks for 2C, but is far too strong to open a preemptive 4S. It is unlikely that 1S will be passed out and even more unlikely that you can make game if partner passes. South may stick in a Michaels 2S cue-bid, showing hearts and a minor; I prefer a bit more strength but not vulnerable vs. vulnerable 2S is reasonable. West shows a limit or better raise by cue-bidding 3H, the suit South is known to hold. Be sure to discuss this with partner, but it should be obvious West does not want to play where South has five trumps. North, with only three trumps, is too flat for any bid; with a fourth trump and some defense he might try 4H, but must be wary of pushing E/W into game. Some would double with North's hand to say "I've got heart support", but I think this will benefit E/W more often than N/S. I prefer the double of a cue-bid raise to show the Ace or King of partner's suit, since he will almost certainly be on lead against a spade contract. North passes and East counts 5 losers (8 likely tricks) with some plus values; there might be slam opposite, say, xxx xxx Axxx AQx. West can cue-bid 4C (if the partnership allows cue-bids to be either first or second round controls, which I recommend) or blast 4NT followed by 6S when West shows two Aces or key cards. The scientific cue-bid produces 4H by West; with no diamond control East settles for 4S and an alert South leads a diamond. The less elegant 4NT forces South to guess; underleading a King against a freely bid slam is unappealing, but a club or heart allows East to dump two losers and claim 12 tricks. Note that on other layouts the diamond lead could be disastrous. Of course South could as easily have had the Ace or AK in diamonds, so I think on average the scientific approach pays.

North opens 2C; while two-suited hands can be somewhat awkward to bid, 22 hcp, five quick tricks and both majors headed by AKQ clearly qualifies for the forcing bid. South replies 2D (negative, waiting or semi-positive) or 2H (Steps, 4-6 hcp.) North starts with 2S; the 2C opening insures his bids are forcing until a suit is bid and rebid. South raises to 3S, showing support, a trick or two, and some slam control; with no control of either side suit and no more than one top trump South should raise straight to 4S. As with board 6, opener can begin cue-bidding to discover the diamond problem, or bash with 4NT. Six of ten pairs stopped at 4 or 5 spades while 4 bid slam, three failing on the obvious diamond lead. A good bidding sequence: 2C-2D; 2S-3S; 4C-4H; 4S-pass, North trusting that South would not skip over a diamond control. For those who require first-round control on the first round of cue-bidding, North must continue with 5C and pass when South retreats to 5S. When East leads the King of diamonds, West should drop the Jack to insure partner continues the suit; playing the 6 risks partner worrying about leading into declarer's AJ. If West overtakes he risks finding partner has made an inspired lead from Kx.

South opens 1H and is not encouraged by partner's 1S response. Best is to rebid 2D, planning to follow with 3C if possible; bidding 2C instead may lose the diamond suit in a confusing fourth-suit auction. North raises to 3D; in general, responder should try to give opener another chance when opener bids two suits and responder has 8+ hcp, as South's 2D bid has a wide range. With fewer diamonds North could take a simple preference to 2H. Don't worry about the fifth spade -- if partner has 3541 shape and enough to bid again, he'll bid 3S over 3D. As it is, the raise improves South's hand; there may be a good crossruff in the majors. However, any move toward slam will carry the bidding beyond 3NT. An optimistic South values his hand at 20 or so (17 hcp + 3 for the void) or four losers (expecting partner to have no more than two hearts) while a pessimist assumes some wasted values in spades. Several Souths declared at 3NT and that seems a practical call at matchpoints. Visualizing, North might have xxxx Kx Qxxxx Kx, but fewer diamonds or some wastage in spades might leave you short of 12 tricks. If South decides to push on, 4C is the obvious move; North's 4S is not encouraging, but as we see from the scoring, 5D loses out to 3NT, 4H,  and 6D.

At 6D, South pulls trumps and runs the Queen of hearts. East covers and South can ruff one heart to set up the suit, finishing with one spade, five hearts (including the ruff), four diamonds in hand, a club and a club ruff. The recap claims 7D can be made but offhand I don't see a likely line.
