Note South's 1 NT response. It's a good idea to play that an immediate raise of partner's major-suit opener shows a constructive hand (i.e., 7-9 HCP). North's 3 ♣ bid is obviously forcing and probably isn't asking for a Club stopper unless South has bid 2 ♠ with a doubleton Spade. South, who was trying to park in 2 ♠, has no interest beyond a part-score contract.

N/S lose one Spade trick and two Diamonds, making four. East may lead the ♣ 2 (low from an honor). South will use their two dummy entries to lead Spades toward the closed hand.

West fishes for a five-card Heart suit in partner's hand, but with no interest in playing in a 4-4 fit with a totally flat hand (4333) they sign off in the notrump game.

E/W take three Spade tricks, two Hearts, two Diamonds, and two Clubs, making three. South will probably lead a small Heart to the ♥ K and ♥ A (declarer shouldn't duck since the ♥ J is necessary as a way to knock out the ♥ Q which turns the ♥ 9 into declarer's second Heart trick). As long as declarer goes after Diamonds first, N/S will come up a trick short of defeating the contract.

North knows that they'll be in slam as long as South has three Hearts, so they use XYZ to find out. When South does have a third Heart, North confirms that Hearts will be trump and then bids Kickback to check on keycards once South tries to sign off in game. North's 3 ♥ bid can be thought of as hand-holding partner. If North jumps to 4 ♠ immediately after South's 2 ♥ bid, South might sit there with a puzzled look on their face. Don't confuse your partner (any more than they are already).

N/S take all 13 tricks when both the ♣ Q and ♥ K are onside. This is a great small slam (75%) but it would be a horrible grand (25%). East will probably lead the ♦ 8 (MUD, although mudding into an honor is usually a bad idea).

If N/S weren't vulnerable, E/W might end up in 3 ♦, but N/S are so E/W aren't. Did you follow that?

N/S lose two Heart tricks, two Spades, one Diamond, one Club, and a Club ruff, down two doubled for –500. East may lead the ♣ Q. Declarer will grab this trick and play a small Heart towards the closed hand. West should duck, East will win the ♥ A, and play a second Club. West will win with the ♣ K and return a Club for their partner to ruff. Spades is a frozen suit, so as long as E/W don't ever lead it, there's no way for declarer to play it for only one loser. Try it!

When you open the bidding, your LHO overcalls, and it gets passed back to you, you should re-open with a double whenever you're short in the overcalled suit. If you have a void in the overcalled suit, you might have to think a bit longer, since that holding often creates problems for the defense. If N/S knew that they could make 7 ♦ (or even 6 ♦), they might not be so eager to beat up on poor West.

E/W lose two Diamond tricks, two Clubs, one Spade, two Hearts, and two Spade ruffs, down three doubled for –800. North will lead their stiff ♠ 3. South will win with the ♠ A and return a Spade for North to ruff. North will cash the ♦ A and continue Diamonds when South encourages. In with the ♦ K, South will play a third Spade, and North will ruff with the ♥ 5. With no reasonable exit, North may lead the ♣ A and continue Clubs to the ♣ J and declarer's ♣ K. Declarer still has to lose tricks to the ♥ A, ♥ K, and ♣ Q. Ouch.

North has no reason to be in Spades with no ruffing values. N/S take four Heart tricks, four Clubs, one Diamond, and three Spades.....if they guess Spades correctly. West's safest lead is the ♣ 7. Declarer will win in dummy with the ♣ Q, cash dummy's high Clubs (West pitching a small Diamond), play a Heart to the ♥ Q, cash the ♣ J (pitching a Diamond from dummy as West pitches a Heart), and lead a small Spade towards the board. West should duck this and force declarer to guess to play the ♠T. If West hops with the ♠ A, the can exit with their remaining Heart, but declarer will win in their hand and finesse the ♠ J (it's more likely that West has the ♠ J when they hopped the first time).

If West ducks the first Spade and the ♠T wins, declarer isn't out of the woods yet. They need to return to their hand with the ♥ J, cash the ♣ J (West pitching their last Heart as declarer pitches a Diamond), and play another Spade towards dummy. If West hops with the ♠ A, again the hand is over since declarer can easily untangle the remaining tricks. If they play low though, declarer will win with dummy's ♠ 8 (they noticed that the ♠ 9 dropped on the first round of Spades). Declarer has to remember to cash the ♥ A while in dummy (pitching their ♦ Q) before exiting with the ♠ K. West's forced Diamond exit gives declarer the remaining tricks with the ♠ Q7 and ♦ A. Nicely played!

North can do the math (er, arithmetic) and figures that their side has a combined 31 HCPs at most. That doesn't quite do it for 6 NT, so they bid a heavy 3 NT. What does "heavy" mean in this context? Well, every once in a while, you'll make a bid that feels like an underbid. It probably isn't--it just means that you don't quite have enough for the next higher bid (a quantitative 4 NT in this case).

N/S take four Spade tricks, three Hearts, one Diamond, and four Clubs, making six on a non-Diamond lead. If West leads a Diamond, N/S lose two Diamond tricks, making five. West will probably lead a major. Oops.

When you're 5-4 (or 6-4 or 7-4 or 183-4) in the majors, don't transfer to your longer major! Ask your partner whether they have a four-card major. If they do, then you'll play in that suit. If they don't you have a lot of options (Smolen, delayed Texas Transfer, parking at the two level in your five-card major, etc.).

N/S lose one Heart trick and one Diamond, making five. West may lead the ♦ Q, and declarer should allow this to hold. Assuming that West continues with a small Diamond (nothing is better), declarer will win, pull two rounds of trump leaving the ♥ Q outstanding, and start cashing Spades. On the fourth round of Spades, East is free to ruff with the master trump, but declarer will simply pitch a Club. East can exit with a Club, but declarer will rise with the ♣ A, ruff their last Diamond in dummy, and pitch their losing ♣ Q on the fifth Spade. Nicely played!

South, with shortness in a side suit, happily bids game when their partner shows a four-card constructive raise in Spades.

N/S lose one Heart trick, one Diamond, and one Club, making four. West will lead the ♦ 5 (fourth highest from an honor). East will win the ♦ A and continue with a second Diamond. Declarer will ruff in their hand and lead a small Club to the ♣ K. The ♠ Q is next, and when the Spades behave the hand is over.

South has no idea whether 5 ♠ is making (nor does West), but a double at the end seems reasonable. E/W lose one Diamond trick, two Hearts, and one Club, down two doubled for –500. That's not all bad, since N/S would have gotten +600 for 5 ♦ making.

If North leads their stiff ♣ J, declarer will win in their hand with the ♣ A (DON'T cover with the ♣ Q!!!) and pull trump in two rounds. A Heart is now played towards the closed hand, covered by the ♥ J and taken with the ♥ A. The ♥ 9 goes to the ♥ Q, and South can cash their ♥ K and ♣ K, but that's it for the defense. Down one.

With a game-going hand, a five-card major, fewer than four cards in the other major, and no singleton or void, transfer to your major and rebid 3 NT. With the same hand and a singleton or void, rebid your longer minor at the three level rather than 3 NT. Partner will bid three of your major with 3+ cards in your suit, bid three of the other major with a five-card suit (in case you have three-card support), or rebid 3 NT with every other hand.

N/S lose one Spade trick and one Heart, making five. The proper way to play the Heart suit is small towards the ♥ Q. If the ♥ Q wins, duck a Heart in both hands. West may lead the ♠ 5.

East's double is intended as a responsive double showing the two remaining suits (on this auction) and the values to take a bid. West does well to pass--partner doesn't have an opening hand, so there's no game here.

N/S lose one Spade trick, two Clubs, two Diamonds, and a Club ruff, down two doubled for –300. Ouch. West may lead the ♦ K (asking four count), but has an easy switch to the ♣ J at trick three.

How does East know that 4 ♥ is Kickback for Diamonds rather than "I'd like to play in 4 ♥." Well, if West wanted to play in Hearts, they would hand-hold their partner by bidding 3 ♥ over 3 ♦ (remember--West's artificial 2 ♦ XYZ bid created a game force). After 3 ♥ sets trumps, West would then be free to sign off in 4 ♥ at their next turn.

On this auction, West doesn't have quite enough to insist on 6 NT (a combined 30 HCP at most), but 6 ♦ has a lot of appeal when East shows a fifth Diamond. It isn't the best slam in the world, but it isn't the worst either.

E/W lose one Heart trick, making six. South may lead a trump. Declarer should win in dummy and immediately go about setting up the Hearts. South will win the second round of Hearts (East can't have a singleton Heart on the auction) and return a second trump, but declarer will win in dummy, pull the remaining trump, return to dummy with the ♣ A, and pitch their losing Club and two "losing" Spades on the good Hearts. If Hearts hadn't split 3-3, declarer would have to fall back on the Spade hook (which also works).

E/W are playing Equal-Level Conversion for takeout doubles, so West can freely double 1 ♣ knowing that if their partner bids 1 ♦ they can "correct" to 1 ♥ to show two places to play. East doesn't get a chance to bid at the one level....or the two level....or the three level....or......

N/S lose one Club trick and one Spade, making five. It doesn't really matter what West leads (well, that's not exactly true, they should probably not lead the ♣ K). How about the ♥ 7?

It's almost always correct to "correct" your partner's 1 NT rebid to two of your major with a weakish hand and a five-card suit. Pretend that your partner opened a weak notrump (12-14). With the South hand, wouldn't you bid 2 ♥ to transfer to Spades and then pass? I would (which probably makes it wrong).

N/S lose one Diamond trick, two Clubs, and three Spades, down one (so much for that advice). West may lead the ♣ 6.

E/W lose one Heart trick and two Spades (either two natural Spade tricks or a Diamond ruff) making four. South will lead the ♥ J, and North will overtake with the ♥ K to switch to their stiff Diamond. When South is in with the ♠ K, they'll give their partner a Diamond ruff. A Diamond lead also works, and South should be able to picture partner's Diamond shortness (West bid 2 ♦ and East raised).

North is happy to play in 3 NT with their total maximum hand, but just in case their partner holds a third Spade they show their fifth Spade on the way. South, without a third (or a second) Spade, bids the notrump game.

N/S take four Spade tricks, two Hearts, one Club, and one or two Diamonds, making two or three. If East leads a small Diamond, N/S make three. If East leads the ♥ K, N/S make two. Which seems more likely?

Declarer will win in their hand, ruff a Spade, lead a small Club inserting the ♣ J when West plays low, ruff their last Spade, play a Heart to their ♥ A, cash the ♣ A (dropping the now stiff ♣ K), and pull the last trump. There's no reason to finesse West for the ♦ K (they have 0-6 HCP, remember?), so declarer should play a Diamond to the ♦ A and a Diamond back towards their hand. When the ♦ K turns out to be doubleton, N/S end up with an overtrick. Sweet.

North feels pretty safe bidding 3 ♦, since they have tolerance for South's Hearts if Diamonds don't; work out. E/W would bid on, but they're vulnerable. Stupid vulnerability.

N/S lose one Spade trick, one Club, and some amount of Diamonds. The proper way to play the Diamond suit is small to the ♦ A and then back towards their hand (i.e., West is more likely to have a void in Diamond than their partner since they presumably have longer Clubs). East will lead the ♣ A and switch to the ♠ 5 (MUD) at trick two.

Interesting auction (to say the least). N/S do well to "right-side" the contract (i.e., force West to be on lead).

N/S lose one Diamond trick and two Spades, making four. West's safest lead is a trump. Declarer will win in their hand, play a Club to the ♣ Q and ♣ A, ruff a Club, pull trump, and lead a Spade towards the ♠ J. West will hop with the ♠ Q and cash their two pointy-suit Aces. Declarer can pitch any stray losers on dummy's good ♣ JT. Nicely played!

It's hard to blame South for their 4 ♠ bid--would you pass with that hand? Did you?

N/S lose three Club tricks, one Diamond, and a Diamond ruff, down two doubled for –300. If East leads something that's not so much a trump, N/S will go down only one. On a trump lead, declarer will win in their hand and probably lead the ♣T, ducked to the ♣ K. West will cash their ♦ A, give East a Diamond ruff, and East will continue with a second trump. It doesn't matter where declarer wins this trick, so they'll win in their hand and lead another Club. East will hop with the ♣ A (dropping the stiff ♣ Q in dummy) and exit with their last trump. Declarer can win in dummy and cash their two high Diamonds, but with three losers in their hand to pitch, they're going to end up down two. Rats.

E/W lose two Heart tricks and two Diamonds, down one doubled for –100. North will lead the ♦ A (asking for attitude) and switch to the ♥ A at trick two.

South can't bid 3 ♣ the first time through--that would show 5+ Clubs and 10+ HCP. When East's minor turns out to be Diamonds (what a shock!), South shows some interest in the hand and North shows a sixth Heart.

N/S lose one Heart trick, one Spade, one Diamond, and a Club ruff, making three. East may lead the ♣ 9. Declarer will hop with dummy's ♣ A and lead a Spade towards their hand. West can't afford to duck, so they'll play the ♠ A and return a Club for East to ruff with the ♥ 5. East's best play now is to underlead their ♦ A to West's ♦ K for a third Club, but declarer can ruff high, ruff a Spade in dummy, and play a Heart back to the ♥ A. When the ♥ J falls, declarer will concede a trick to the ♥ Q and claim the remaining tricks.

South's 4 ♥ jump can't be anything other than Kickback for Diamonds. If it was Hearts, they would have bid 2 ♥. Duh.

N/S lose one Heart trick, making six. East may lead the ♣ Q, but nothing matters.

If you're curious why 6 ♠ makes when West apparently has two tricks (the ♥ A and the ♠ J), here's how (it's a Trump Coup):

1) ♥T to the ♥ Q and ♥ A
2) ♥ J to the ♥ K
3) Heart ruff
4) Spade to the ♠ K
5) Diamond to the ♦ A
6) ♠ A pitching a Heart
7) Club to the ♣ K
8) ♣ A pitching a Diamond
9) Club ruff
10) Diamond to the ♦ K
11) ♦ Q
12) Club from dummy overruffing West's forced ruff
13) Winning Spade

South does well not to sit for 2 ♠ doubled (i.e., it makes for a jillion trillion points).

E/W lose one Spade trick, two Diamonds, and two Clubs on double-dummy defense. If South leads a trump (entirely reasonable), E/W will make three. Best is the ♦ A followed by the ♣ 2 to partner's ♣ K and a small Club return. West will cover the ♣T with the ♣ J, and declarer will ruff low in dummy. Declarer will most likely play a small Spade to their hand and finesse against South's ♥ K. With no fast way back to their hand, declarer will play a Spade, but North will hop with the ♠ A and lead another Club through declarer's ♣ Q5. South will cover whatever is played, and declarer will ruff with dummy's last trump. Again, with no fast way off the board, declarer will most likely lead a Diamond, but South can win with the ♦ K and cash the ♣ 7, down one. Nice defense!

North almost goes, but in the end they know they have a working five count. They can't quite appreciate the fact that their doubleton Heart is exactly what partner needs. Oh well.

N/S lose two Club tricks and one Spade, making four. West can't lead Spades enough times to be a nuisance without giving up their natural trump trick. West will lead a high Diamond, ruffed in the closed hand. The ♥ A and ♥ K are next followed by a Heart towards dummy. If West ruffs with the ♠ Q, declarer will simply discard a minor-suit card. If West pitches a Club, declarer will ruff in dummy, cash the ♣ A, ruff a Diamond, ruff their last Heart (West again in the same dilemma), and ruff a Diamond with the ♠ J. That's eight tricks and declarer still has the ♠ AK in their hand. Sweet!

E/W lose two Spade tricks and one Club, making four. It doesn't really matter what North leads, as long as N/S cash out when they're in with their Club winner. If North leads the ♠ K and continues Spades, South will clear the suit, but declarer can safely duck a Club to North's ♣ Q, and North has no more Spades to continue--five Club tricks, one Spade, three Hearts, and one Diamond appear to be ten tricks (check me if you have any doubt).
