On the day that negative doubles were first invented, they were used to say "Hey, I have 4+ cards in the unbid suits!" By the afternoon of the second day, they had been changed to "Hey, I have 4+ cards in the unbid majors!" That said, if you make a negative double at the three level or higher, it's a really good idea to have (1) cards in both of the unbid suits or (2) tolerance for partner's first suit.

South could certainly have cuebid Diamonds at their first opportunity to show a limit raise or better in Hearts, but the negative double isn't wrong with such a strong holding in Diamonds. For the same reason, 3 NT looks to be a better contract than 4 ♥, since it's likely that Hearts won't be breaking nicely. N/S take five Heart tricks, two Clubs, two Spades, and one Diamond, making four. If N/S play in 4 ♥, they'll take the same ten tricks since they can't afford to ruff any Clubs in the South hand and still pull trump without a trump loser. West will lead the ♦ J.

East has no reason to make a re-opening double with such strong Hearts. N/S lose one Club trick, five Hearts, and one Spade, down one. If declarer tries to pull trump, they'll lose control of the hand and go down more than one. Ugh. Best is for declarer to play high Diamonds to shorten East's trumps and then pull one round of trump somewhere in the middle of the hand. If E/W don't tap declarer with Clubs at every opportunity, N/S might actually take seven tricks. West will lead the ♣ K.

N/S take five Club tricks, two Diamonds, two Hearts, and two Spades, making five. West may lead a small Spade, and declarer should play low from dummy (the Spade finesse can wait if it's on). When the ♠ J wins the first trick and East switches to a small Diamond, declarer should be able to figure out the Spade position and drop the stiff ♠ K on the next round of Spades.

If you're East and you pass your partner's 2 ♦ bid, make sure you're ready to apologize if West's hand is ♠T9532 ♥ KQ7 ♦ AQ5 ♣ KT.

E/W lose one Spade trick and four Hearts, making two. South should lead the ♠ K.

N/S take two Heart tricks, two Spades, and one Diamond, down two. If West doubles 1 NT for penalty (if that's available to them), East will happily pass and E/W will collect +500. Heh.

If East leads the ♥T (interior honor sequence), N/S will take six tricks. That's unfortunate for E/W, but it's difficult to call that a bad lead. The ♦ 6 or ♣ 3 work much better.

With 4333 (flat) distribution, West has no reason to look for a 4-4 Heart fit. That said, they definitely have a reason to look for a 5-4 Heart fit. When East doesn't have five Hearts, West parks in the notrump game.

E/W take two Spade tricks, three Hearts, four Diamonds, and one Club. South may lead the ♠T (i.e., there's absolutely no reason for them to try and set up their Diamonds with zero HCP).

West knows the hand will play better in a major suit, so they use Garbage (Crawling) Stayman to get there. If East had responded 2 ♦, denying a four-card major, West would have bid 2 ♥. If East had only two Hearts, they would have "crawled" up to 2 ♠ and played in their 4-3 Spade fit. On this hand, East has a four-card Spade suit, so none of that matters. Yay.

E/W lose three Spade tricks and two Hearts, making two. South may lead the ♥ 2, declarer overtaking North's ♥ Q with the ♥ A. A small Spade goes to North's ♠ Q, the ♠ K is cashed, and a small Heart is returned to South's ♥ K. South should cash the ♠ A, but they'll be stuck for an exit. Since a Heart will give declarer two Heart tricks (i.e., the ♥ J9 are in dummy), and a Diamond will be run around to the ♦ AQ, South will be forced to exit with a Club. North shouldn't play the ♣ Q, and declarer will win cheaply with the ♣ 9. The ♦ A, Diamond ruff, ♣ A, ♣ K, ♥ J, and Heart ruff get declarer up to eight tricks.

South can't afford to bid 3 ♠ over their partner's 3 ♣ cuebid, since that would show a sub-opening hand. Without anything better to bid below 3 ♠, South opts to bid the game and hope. Luckily, their partner has the world's best hand (You rock, partner!).

N/S lose two Diamond tricks, making five. West will lead the ♣ 9 (top of nothing in a supported suit).

South doesn't have enough juice to make a takeout double the first time through the auction, but when the opponents sign off in 3 ♥, they find the.....nerve (SFW) to enter the auction.

N/S lose one Heart trick, one Diamond, and one Club, making four when the hand turns out to be uber-friendly (as in very friendly....not friendly to people who drive you around town for money). East will lead the ♥ Q.

East shows their invitational hand and "signs off" in 3 ♥. If West was at the top of their range (13+ to 15), they would certainly bid on, but with only 12 HCP, they justifiably pass.

E/W lose one Diamond trick, one Club, and one or two Hearts, making somewhere around 3.5 Hearts. South will lead the ♠ J. Declarer should win in hand with the ♠ A, play a small Spade to the ♠ K, and then ruff a Spade. It does North no good to ruff with the ♥ J, so they'll discard a small Club (upside down attitude showing a fondness for Clubs). The ♦ Q is next ducked to North's ♦ K. North will cash the ♣ K and exit with a Diamond. There's no way that declarer will know to win this trick on the board and lead the ♥T through North's ♥ J, but that turns out to be the only way to hold the Heart losers to one. Oh well.

East will lead the ♦ 8, but a Diamond lead doesn't work as well when N/S are in notrump. Rats. N/S take one Spade trick, five Hearts, five Diamonds, and three Clubs for 14 tricks (more or less).

East's double of North's artificial bid isn't insane--it just turns out to be a.......freaking (SFW) disaster. In 2 ♥ redoubled, N/S lose one Diamond trick and one Heart, making five for +1240. If you're E/W, be thankful that you aren't playing for a dollar a point. If you are, that would be....um, carry the two....right around $1,250 dollars.

For those who say "You need 48 HCP to be in slam!", please count the HCP on this hand (subtracting HCP that are irrelevant such as the ♣ K). I come up with 22. That's not very many.

E/W take three Spade tricks, three Hearts, five Diamonds, and a Heart ruff in dummy, making six. Since there's no way to make the hand if North holds the ♠ K, South will be forced to finesse South for that card. When that works, the hand is over. South will lead the ♣ 8 (MUD).

East shouldn't rebid 3 ♣ after West's 2 ♥ bid, since that would show extra shape or extra values. E/W lose one Heart trick and one Club, making five. North may lead one of their Aces (or a small trump), but nothing much matters.

E/W lose one Spade trick, two Hearts, and one Club, making three. South will lead the ♦ 7 (beer card and MUD). North should NOT cover if declarer sticks in either the ♦ Q or ♦ J. South obviously didn't lead away from the ♦ A, and if South has a singleton Diamond, declarer holds ♦ A76. In that case, the proper play will be to cover the second high Diamond. If South has ♦ 76, nothing matters, since declarer will never lose a Diamond trick. If South has ♦ 976, then declarer has a stiff ♦ A and covering would be stupid.

West wouldn't have been wrong to rebid 3 NT after partner's 1 ♠ bid, but their 2 ♦ game forcing bid is fine. When East shows a doubleton Heart and a balanced hand, 3 NT makes more sense.

E/W take two Heart tricks, four Diamonds, three Clubs, and one Spade, making four. South may lead the ♣T.

East's negative double at this level shows 10+ HCP and four or more cards in each major. West, with absolutely no preference between the two suits, asks their partner to pick.

E/W lose one Heart trick and one Club, making five. South will lead the ♣ 6 (MUD). Declarer will ruff the Club continuation and pull trump in two rounds. With North being MUCH more likely to be short in Hearts than South, declarer will cash the ♥ K and lead a small Heart covering anything that South puts on the table (i.e., any card that South puts on the table...covering South's convention card, sandwich, or hand would be weird).

East's hand is about the minimum you'll ever hold for a game-forcing jump shift. A 2 ♦ rebid wouldn't be wrong. When West tries to sign off in 3 NT, East decides that the hand will probably play better in a suit contract, so they rebid their Diamonds. West has a clear preference.

E/W lose one Heart trick, one Spade, and one Club, making four. South may lead the ♦ J.

E/W lose one Heart trick and one Diamond, making five. North may lead the ♠ 8 (MUD). Declarer will win in their hand with the ♠ A, cash the ♥ A (noting the fall of the ♥ J), and lead a small Heart covering any card that North puts on the table. North will most likely play small on the second Heart, so declarer will with with the ♥ 7 and lead the ♦T towards their hand. South will most likely hop with the ♦ A, although it wouldn't be wrong to duck, and exit with the ♣ J, taken on the board with the ♣ A. A Spade to the ♠ A, ♦ K pitching a Club, and a Heart towards dummy's ♥ QT8 end the drama.

South does well to find the 5 ♦ sacrifice on this hand. N/S lose one Heart trick, one Club, and two Heart ruffs, down two doubled for –300. East will lead their stiff ♥ 3. West will win the ♥ A and return the ♥ 2 (lowest Heart asking for a switch to the lowest ranking side suit). East will ruff and dutifully return the ♣T. West will win the ♣ A and return the ♥T showing a possible entry in Spades (highest Heart asking for a switch to the highest ranking side suit) in case East holds ♦ J42 (i.e., East would be able to overruff North's ♦T on the fourth round of Hearts). When North turns up with the ♠ A, the hand is over.

South's double typically shows around 7-9 HCP and no clear direction. North is welcome to pull the double with an unusual hand (♠ Kx ♥ A ♦ AKxxxx ♣ Jxxx perhaps). E/W lose two Spade tricks, one Heart, and three Diamonds, down one doubled for –100. That's too bad (for E/W), since N/S would have collected only +90 for 1 NT making. Sigh. North will lead the ♠ 7.

Although N/S play XYZ, there's no reason at all for North to bid 2 ♦ to create a game force on this hand. South's 1 NT rebid guarantees at least two Hearts--where does North think that they'll play the hand? Yup, 4 ♥.

N/S lose one Heart trick and two Clubs, making four.....if East finds a Club lead. That's very unlikely holding ♣ J765, since East is much more likely to lead the ♦ J or a trump. On either of those leads N/S make five, when declarer is able to pitch a Club on the ♦ Q.

E/W lose one Spade trick and one Club, making five. It's highly unlikely that declarer will lead to their ♠T on the first or second round of Spades--why should they? North will probably lead the ♦T (interior honor sequence). Declarer will pitch a small Club from dummy and win in their hand with the ♦ A. A Diamond ruff in dummy is followed by a Club to the ♣ Q and ♣ K. Surprisingly, the best thing that North can do is to continue with a Diamond giving declarer a ruff-sluff that they don't need! If declarer ruffs in their hand, they'll be limited to only ten tricks, so they'll ruff on the board with the ♠ 7 and pitch a small Heart from their hand. A Heart to the ♥ A and a Heart back to dummy (covering any card that North plays) allow South to ruff, but that's the last trick for the defense.
