Quite an involved auction right out of the gate. No bid quite describes South's hand at their first turn--3 NT would show 3334 shape and 13-15 HCP, and no immediate Spade raise does the trick either. This is the one hand shape where a 2/1 auction begins with responder bidding a 3-card suit.

It's not a good slam, as N/S need Hearts to be 3-3 and the ♦ K to be onside. Once again, a victory for the glass-half-full crowd. N/S lose only one Heart trick. The ♠ 4 looks like a reasonable lead on the auction (i.e., very unlikely to give up a trick when N/S have shown ♠ AKQ).

Most N/S pairs will make 3 ♠, since the defense is not an easy one to find. East will lead the ♥ 4, and West wins the ♥ Q and ♥ A. At trick three, West has to play back their singleton Club, which looks odd when dummy holds such an intimidating suit. Declarer wins the trick, and starts in on trumps. West has to hop up with the ♠ K and play a small Heart (signaling for a Club return). East ruffs with the ♠ A and plays back a Club so West can ruff with their remaining trump. Nicely defended!

Michaels cuebids show either a weakish (5-11 HCP) or strong (16+ HCP or equivalent playing strength). Here, North clearly has the strong version. To show the weak Michaels hand, the overcaller simply passes any non-forcing bid by partner. To show the strong Michaels hand, the overcaller does anything else.

N/S lose two Spades and a Diamond. The opening lead will most likely be the ♦ A, and the hand is quickly over.

N/S can collect two Club tricks, two Diamond tricks, and the ♠ A on any defense, so most E/W pairs will make 2 NT. The ♥ J would have been a reasonable lead on the auction (i.e., West denied a 4-card Heart suit), but partner doubled for a Club lead so North should probably lead the ♣ K.

Declarer collects three Diamond tricks, two Club tricks, two Heart tricks, and two Spade tricks without having to resort to a guess in Hearts. If West is a good guesser, and N/S don't hit on the Club opening lead (would you?), they're likely to make two overtricks. Expect +430 to +460 to be par on this hand.

East clearly doesn't have a bid the first time through, but after North bids 1 NT and the auction appears to be dying, East has an automatic double for the "round" suits (i.e., Hearts and Clubs). South redoubles to show that the hand belongs to N/S. West shows a preference for Hearts, and North shows their 3rd Spade. If not vulnerable, East would surely compete to 3 ♥, but the fire-engine red color in their direction keeps them quiet.

N/S lose two Hearts, two Diamonds, and one Club. The ♦ K will be the likely lead followed quickly by the ♥ Q.

The 1 NT overcall by West looks automatic, but some might not find it. I can't imagine passing with that hand, and every other bid looks wrong. What's the worst that can happen? East might transfer to Spades holding xxxxx xx xxx xx--so what? You need to be in the auction.

E/W lose two Hearts and a Diamond. Best defense will be ♥ 7 to the ♥ K followed by ♥ A and another Heart. It doesn't much matter here, as declarer can ruff one Diamond in dummy and pitch another on the ♠ A, making four.

West almost has enough to make a move towards game, but not quite. Even if they do, East would definitely say "Stop bidding, you." The hand is friendly, and +170 will be a common result. E/W lose one Spade, one Heart, and one Diamond. The ♠ K is a likely lead.

West has to be careful not to fall in love with their hand--some will, and South will happily double anything higher than 2 ♠--that's the way South rolls. When both opponents are bidding, and you hold 17+ HCP, how many points do you think your partner has? Yeah, not very many. How do you think you're going to get to their hand for all of those fun finesses? Yeah, you're not going to. The same kind of thing happens when you try and play 2 NT with 20 HCP opposite zero. Down three anyone?

N/S lose one Heart, one Diamond, and one Club, although +140 may be more realistic. West can't effectively lead a Spade on opening lead, so the hand plays one trick better for South than it would for North. I would refuse to make an opening lead if I were West--see how long you can sit there until they call the director.

Get used to creating at the table. When West picks up their hand, they're pretty sure they want to play in 5 ♣ or 5 ♦ (or higher). Why not tell partner that at your first opportunity? 4 NT is an obvious way to do that. If partner thinks you're using Blackwood, get a new partner.

In 5 ♠, West has to guess correctly which minor-suit Ace to cash on opening lead. If they refuse to play either one and start with their singleton Heart, 5 ♠ is down one. If they start with the ♣ A, 5 ♠ makes. Bridge is cruel.

If the hand is played in 5 ♦, it's likely that South would lead a high Spade on the go, but a Club switch at trick two would be automatic. E/W lose one Spade, one Club (the ♣ Q), and a Club ruff for down one.

Not much to discuss on the auction. When your partner preempts, and you want to "extend the preempt," bid to the level of your total trump (i.e., 3 ♦ with three trump, 4 ♦ with four trump, etc.) South has an easy 5 ♠ bid on the auction. Discuss with your partner whether a double by South in this auction would be responsive showing both majors. I like to play responsive doubles through 4 ♦, so a double at this point would be for penalty (or at least cooperative).

N/S lose one Diamond and one Club. E/W don't have an effective sacrifice in 6 ♦ due to the vulnerability being equal. The ♦ 7 is a likely lead (beer card).

It's impossible for E/W to get to slam on this hand. Now that I said that, I imagine that this hand will be perfectly flat with all E/W pairs in 6 ♥. Sigh. E/W lose only one Diamond. The ♣ J looks like a reasonable lead, although some South's will lead the ♠ 5 or the ♦ Q. Nothing matters on this one.

East is going to be fuming by the time they leave for the next table. Snicker. N/S lose one Heart and one Diamond. If West has peaked at the hand record, they'll pull 5 ♠ doubled to 6 ♣. Without that bit of foreknowledge, they're going to pass just like everyone else. West will lead the ♣ 3, and the hand will be over almost before it begins.

You have to have some pity for poor South. Not only did East ruin their nice preempt, partner doubled trying to get them to bid 2 ♣ holding ♣ 863. Ugh. In real life, North will probably bid 2 ♥ over 1 NT, and N/S will not be happy. Even on the auction shown, N/S are likely to make a misstep and allow E/W to make 1 NT doubled. Ugh again. North has to try not to squish South's ♦ Q--not an easy task.

West's hand certainly looks like it's worth a 1 NT opener (the 5-card suit is far more valuable than a stray Jack). East probes for a 5-card major in opener's hand, and when none is found dutifully bids game. E/W take five Club tricks, one Diamond, two Hearts, and a Spade. If North leads the ♥ 4, E/W will make four. Best lead is the ♠ 6.

South should show their suit the first time through. That way, when they subsequently double, their hand shape will be more defined (5-card Club suit and 3-card support for the unbid suits). E/W dare not compete higher on the vulnerability.

N/S lose two Hearts and a Club (or another way to look at it, N/S take five Diamond tricks, four Club tricks, and the ♠ A). If E/W attack Spades early, then declarer pitches their small Club on dummy's third Spade. The ♥ Q or a trump are both reasonable leads.

While 3 NT makes, it's not a good contract needing (1) the ♠ A onside, (2) Diamonds to split 2-2, and (3) the ♣ J to fall. Let's see.....that's about a 12% game. If West forgets to bid, N/S will get a top with +180. West should lead the ♥T against 3 ♦, but it doesn't much matter as N/S lose one Heart and one Spade, making five.

West, with a minimum hand and more Clubs than they've indicated up to this point, has an easy pull to 4 ♣ after East's double. E/W lose one Spade, one Heart, and a Diamond, when declarer has to pull trump before they can ruff their two Diamonds losers. A high Heart will be the opening lead.

When your partner opens and rebids 1 NT, they're showing a balanced or semi-balanced hand with 12-14 HCP. If you hold a hand that would have transferred to your major and passed if partner had opened a weak notrump (12-14 HCP opener), then rebid your major at the two level to play.

E/W lose two Spades, two Hearts, and a Diamond, making two. It's very hard for N/S to find their Club part score, and the N/S pairs who enter the auction are more likely to play in notrump with mixed results. South will probably lead their ♣ J on opening lead, and E/W will likely make an overtrick for +140.

Although East has a hand with the strength to redouble, it's the wrong shape. If you have shortness in an unbid suit, it's usually better to make a natural bid as responder after your RHO makes a takeout double.

East uses XYZ to show an invitational hand with exactly five Spades. West has an easy raise to game. E/W lose one Spade and one Club if declarer guesses correctly in Spades. If South leads a trump (not wrong), declarer will have no trouble in Spades, making five.

If North opens 1 ♦, E/W will play in either 2 ♠ or 3 ♣. With North opening 1 NT, it's anybody's guess. If South doesn't double 2 ♥, E/W may very well play there for –100. In 2 ♠, E/W lose one Club and three Diamonds. North will probably lead the ♦ A and switch to Spades at trick two.

South likes the ♠ Q, and happily bids the notrump game. There's no reason for South to try and play the hand in Spades, since they have no ruffing values. N/S take five Spade tricks, one Heart, two Diamonds, and a Club. 4 ♥ would be an easier contract, but it's hard for South to bid past 3 NT. West will probably lead a small Club on opening lead, but it won't matter. South's ♣ QT9 holding guarantees a second Club trick if E/W pursue Clubs, resulting in N/S making four for +430.

West should assume that East doesn't hold a 4-card major when East responds 1 ♦. When West doesn't rebid 1 NT, East alerts their bid as "Showing an unbalanced hand unsuitable for notrump." East has an easy 3 NT rebid. E/W take two Spade tricks, three Hearts, two Diamonds, and four Clubs, making five for +660. The ♠ 7 is a likely lead on the auction.

South's unusual hand shape allows them to take a second bid after they've preempted, although that's typically a no-no. N/S lose two Spades and a Club for down one. E/W would have lost one Heart, one Diamond, and one Club in 4 ♥, although the play wouldn't have been easy. It's likely that West will lead the ♥ 7 on opening lead, although the ♣ 7 is also possible.

East has to be very careful on the auction. When their partner can't take a bid over 1 ♦, East should let the hand go. Not only do they have the lowest-ranking suit, they have a hand that is quite likely to take seven tricks and nothing else. Here, with their partner holding the ♠ Q, they can take an eighth trick, but that's still down one in 3 ♣, probably doubled. That said, the N/S pairs are more likely to bid 3 ♦ than double 3 ♣, so East gets away with their overbid.

N/S lose two Clubs and two major-suit tricks, depending on how declarer endplays East. West will likely lead the ♣ 8 on opening lead, and after two rounds of Clubs, East will likely exit with a trump. Declarer plays off ♦ KQ leaving the ♦ A in dummy followed by ♠ A and a second Spade. East can't jettison the ♠ K without giving dummy two Spade tricks, so they're forced to win the second Spade. Now, a third Club gives N/S a ruff sluff and a Heart eliminates N/S's Heart loser. Rats.

E/W should reach the decent Spade game, losing two Spades and a Heart when Hearts split badly. Best lead from North would be a trump, and South exits safely with ♠ A, ♠ K, and a third Spade. Some declarers will misplay the Hearts and come up a trick short, although that shouldn't happen when East can play the ♥ Q and let South hold the trick. South can't return a minor suit without giving declarer a trick, so they'll return a Heart. Declarer wins in dummy, plays another Heart winner (throwing a Diamond), and ruffs the suit good for a later Diamond pitch. E/W collect one Spade trick, three Heart tricks, two Diamond tricks, two Club tricks, a Heart ruff in declarer's hand, and a Club ruff in dummy, making four for +620. Nicely played!

  1. Alert, artificial asking for more information about West's raise
  2. Alert, artificial showing 4-card Heart support and a minimum hand
  3. Always going to game, but 3 NT would be the better contract if West had only three Hearts

East uses Wold 2 NT to check to see whether West has four Hearts and whether West has a minimum or maximum hand (7+ losers or 6 losers). When West shows a minimum, any thoughts of slam that East might have had vanish. E/W lose one Heart and one Spade. South can't lead a Club on opening lead without giving up their Club trick, so declarer can get the Diamonds wrong and still be able to pitch their slow Club loser, making four. If they guess correctly in Diamonds, they'll make five. The ♥ Q looks like a reasonable lead, since South holds the ♥ 9.

Declarer plays off the two two Hearts, leaving the master trump outstanding. Then a Diamond to the ♦ A, the ♦ J for a finesse (North should not cover), the ♦T to the ♦ K, and when the Diamonds split, a fourth Diamond pitching a Club from dummy. South can ruff in and play the ♣ K, but declarer quickly wraps up 11 tricks by ruffing a Club and conceding a Spade.

  1. Showing 15-19 HCP
  2. Close call between 3 ♠ and double

If E/W were vulnerable as well, West might choose to double on the assumption that East held something like ♠ AKxxxx or a side entry. With East making a 3rd seat, non-vulnerable preempt, it's too likely that E/W won't be able to establish their Spade tricks on defense, so West takes the safe route and bids 3 ♠.

E/W lose two Spades and two Hearts when East's Diamond loser goes away on dummy's fourth Club. South starts with ♥ A and another Heart, North winning. North now plays a small Diamond, and South's ♦ J is taken in dummy with the ♦ A. Remembering that South bid 2 NT vulnerable, declarer should assume that South has ♠ KJx and play a trump to the ♠ A. Now, ♣ Q is played. South should cover, and declarer wins in dummy with the ♣ A. Club back to the ♣T and a third Club to dummy's ♣ J. On the 13th Club, declarer pitches their losing Diamond. South can ruff, but that and their high trump are the last two tricks for the defense.

  1. Game forcing, showing an A, K, or 2Q
  2. Best rebid showing 22-24 HCP
  3. Transfer
  4. Showing five Hearts and four Spades

West should treat their hand as a 4-5 hand in Spades and Hearts respectively. If East bids 3 NT over 3 ♠, then West can bid 4 ♥ to show 4-6 shape. East's hand is a little too good to risk opening 1 ♣ followed by a 2 ♠ reverse. If you are squeamish bidding 2 NT with a singleton, simply stick the ♦ 2 in with the Clubs and feign ignorance when your hand hits the table ("How'd that get in there?")

Some E/W pairs will play in slam, but that's a bit pushy with a combined 28 HCP. To make six, E/W need the Spade finesse to be right and locate the ♥ Q. That's a lot to ask for, and 4 ♥ making six for +680 will be a reasonable result. North will likely lead the ♣ Q on opening lead.

  1. Showing the unbid suits and emphasizing Hearts
  2. Alert, support redouble showing exactly three Spades

Since E/W play Sandwich NT, West is able to double as a passed hand to show both red suits while guaranteeing five Hearts. If West had bid 1 NT instead (alertable), they would be showing exactly four Hearts and longer Diamonds.

E/W can't afford to be down two doubled, so East reluctantly passes rather than bid 4 ♥. N/S lose one Heart, one Diamond, one Club, and a trick "in the wash." The phrase in the wash means that some other trick will be lost, but it's unclear what it will be since it depends on the defense and how declarer goes about playing the hand.

For this hand, the extra loser is going to be either a second Diamond trick or a Club ruff if E/W start off with a Club to the ♣ K and a second Club. With that defense, declarer will be unable to ruff their third Diamond in dummy without either risking a Club ruff or allowing East to pull a third round of trump. Interesting hand.

North is pretty sure that 1 NT is going down, although there are no guarantees. E/W take two Spade tricks, two Club tricks, and two Diamonds for down one. N/S should be pretty happy with +100. If N/S attack Hearts, it's very easy to see how 1 NT might make. North's best lead is the ♣ 6, although few will find it. A small Spade also works, as long as South plays low (not too hard to figure out, since they can count all but two of the Spades).

  1. Forcing

South's hand is much too good to pass their partner's preempt. It's a good idea to play that a new suit bid by responder after a 3-level preempt be forcing. If North had a singleton Spade, then 4 ♥ would be their rebid.

N/S lose one Spade, one Diamond, and one Club. East's best lead is probably the ♥ 9, although the ♠ A and another Spade wouldn't be wrong.

  2. A weak to constructive raise of partner's suit
  3. Why not?

E/W lose two Clubs, one Diamond, and a Spade for down one. It's difficult for East to pass on the auction, so they have our sympathy. The ♣ K will be the opening lead, and South should switch to a Diamond at trick two when North shows three Clubs. If South doesn't switch, then four Hearts will make. Oops.

N/S lose one Spade, one Diamond, and one Club when the ♣ J falls under the ♣ A. When Clubs are 3-1, declarer's best line is to simply cross-ruff in order to score their trumps separately. The ♠ 8 will be the opening lead.

E/W lose a trick in each suit for down one doubled, –200. That turns out to be a good score, since all N/S pairs will be in 4 ♥ making.....except for the ones who aren't. Stupid N/S pairs.

South will start with the ♥ A, and when it's apparent that declarer has a singleton Heart, switch to the ♣T at trick two. North should realize that South doesn't have a singleton Club (i.e., they didn't lead it at trick one), so a Diamond switch at trick three looks right.

  1. Obvious

If you play XYZ, responder can bid 2 ♦ at their second turn to create a game force. That said, 2 ♦ should be used only when there isn't a better bid available. East knows that their partner holds at least two Spades for their 1 NT rebid, so 4 ♠ is going to be the final contract. When partner has limited their hand and you know where to play the contract, get there quickly.

E/W lose two Clubs and possibly a Spade if they're unable to find the ♠ Q. Declarer has no reason not to play for the Queen to drop doubleton, so expect most E/W pairs to be +420. The ♦ 7 is a reasonable lead.
