Partner led the  9. Your partnership agreement is to lead the highest card from three small ("top of nothing"). So, partner might have started with any of three possible spade holdings: the singleton  9, a doubleton spade  9 x, or all three of the missing spades 9 8 6. Declarer called for the  A from dummy. Your play?

ANSWER: Play the  J, showing the  10 and suit-preference for hearts. By convention, signaling with an honor normally shows the next lower honor in sequence. Thus, playing the  J shows that you hold the  10 as well. But here nobody cares that you have the  10. More importantly, an unusual high card (the  J) shows suit-preference for the higher-ranking side suit.

  • If partner had a singleton spade, let's hope she has the  A and another diamond; she can win the first round of diamonds, and lead to your  A to get her spade ruff for down one.
  • If partner had a doubleton spade and the  A, she'll need to lead a heart when she wins the first round of diamonds. Otherwise, declarer can discard heart losers on dummy's spades to make five if declarer's shape is 1=2=6=4 (or even six, if declarer has the  A too).
  • If partner had three spades to start with, declarer will discard a loser on the  A and partner will realize you are showing her where your side-suit winners are.
THE PRINCIPLE: The play of an unnecessarily high card is always a suit-preference signal. You could have played the  7 as an encouraging signal in spades; the smaller spades still concealed in your hand ensure that partner would recognize the  7 as a "high encouraging" spade.

BONUS MINUTE: If you held the  A instead of the  A, you would have played the  2 as suit-preference for clubs. With so many spades in your hand, it is unlikely that a spade continuation is a possibility. More likely, partner had a singleton or declarer is void; in either case, partner will be trying to read your card as a suit-preference signal.

Take Out Some Insurance

Suggested soundtrack: the Jimmy Reed blues classic from 1959, "Take Out Some Insurance"
In this installment, you and partner are playing "1430" key card responses to a 4NT query. There are five key cards: the four aces and the king of trump. Responses show 1 or 4 key cards (5♣), 3 or 0 key cards (5), or 2 key cards without (5) or with (5♠) the queen of trump.

Partner deals and opens. The opponents Pass throughout the auction.
You hold
  ♠ 10 7 5 3 2    4   ♦ A K Q J 7    J 4.

Partner You
1  2 NT1
3 2 4 NT
5 3 ?
  1. game forcing raise
  2. singleton or void in clubs
  3. one or four key cards
You have far too much playing strength for a 3  limit raise. A splinter raise of 4  is a possible bid, but partner will never expect five-card support and a solid source of tricks in diamonds in addition to the heart shortness.

You decided on a game-forcing Jacoby 2NT raise, fully expecting partner to show shortness in diamonds, but instead she showed a singleton or void in clubs. At most one club loser, at most one heart loser, a ten-card trump suit... even if partner has just a minimum opener, a slam seems very possible.

Your 4 NT bid asked for key cards; partner's 5 response showed either one or four key cards. Well! With four key cards over there, making 7  would be simple; draw trump, cash the outside aces, ruff dummy's club loser, and ruff the fifth diamond if necessary.

So, your call?

ANSWER: Cool your jets. Bid 5  to play. Because, what if partner has only one key card? Partner has no diamond honors, and at most one club; is it even possible that partner could have an opening bid with only one key card? Yes, it is possible, and if so even 5  might be too high. But if partner really does have four key cards, she will bid on over your signoff.

THE PRINCIPLE: When partner shows two possible holdings in a key card auction (one or four, or zero or three) and you can't make a slam across from the minimum, sign off at the five-level. That way, you take out some cheap insurance against partner having the minimum holding. If partner has the maximum holding, she'll keep the auction going.

For example, if partner has
  A Q J 8 6 4 K Q 9 6 10 6  9
she will pass 5  in a heartbeat.

But if she instead has
  ♠ A K J 8 6 4 A 9 6 5 10 6 A
partner will bid 6  to let you know she has four key cards, and you can take over from there.

If partner has the extra key cards and a side-suit king, she should cue-bid the king if it is possible to show it without going past six in our trump suit. For example, holding
   ♠ A K J 8 6 4  A K 6 5  10 6  A
partner will bid 6  to show four key cards and the king of hearts.

In a matchpoint game, declarer showed 22-24 high card points and denied a four-card major. You led your fourth-best heart. Dummy's  J held, as partner followed with the  6 and declarer played the  10.

Declarer led the  6 from dummy, partner played the  2 and you won the trick with the queen over declarer's jack.

What now? Partner denied any heart honors. Maybe switch to a black suit? If partner has the  K, she can get in and lead spades through declarer to your ace-queen. If partner has the  K, leading spades will hold declarer to nine tricks. What do you lead now?

ANSWER: Lead a heart. Partner doesn't have a king. Declarer's 2 NT rebid showed at least 22 high card points. You have 10 HCP, and dummy has 6. That accounts for 38 points, so partner has at most two points: a queen, or two jacks. If declarer has a full 24, partner doesn't have any face cards at all!

THE PRINCIPLE: When declarer has indicated a specific point-count range, use that information to figure out how many high card points partner can have. Add your point count to dummy's and declarer's; the rest must be in partner's hand. This is commonly referred to as "how much room (for high cards) is there". With at most 2 points, there is no room for a king in partner's hand. You can use the same principle as declarer: if one defender has shown a specific range during the auction, you can similarly estimate the strength in the other defender's hand.

Why continue hearts? Declarer clearly has all the kings. So, leading a spade gives up a trick. If partner has the  Q (there is room in her hand), leading a club will finesse partner's queen rather than making declarer guess how to play the club suit. (If partner has the  Q 10 9, she doesn't need your help.) Underleading your  10 would give up a diamond trick if declarer originally held  A K J 9. You know that declarer has only two hearts remaining -- the ace and king -- because she denied a four-card heart suit during the auction, and partner denied a heart honor at trick one. So declarer started with the A K 10; leading a heart is a safe exit, any other suit lead has nothing to gain and might give up a trick. The full hand:

BONUS MINUTE: Your best chance to defeat the contract is that either declarer bid 2NT with a singleton  K, or else upgraded a 21-count with only the jack-small of spades (leaving room for partner to hold the king). To take advantage of those possibilities, you'd have to play  A and then  Q; but if you're wrong, declarer makes an extra overtrick. Those are very specific and unlikely cases; at matchpoints it is better to play the percentages and lead a heart. However, playing rubber bridge or IMP scoring you usually ignore overtricks and take the best chance to defeat the contract, however unlikely; here, you might go for broke with the  A Q of spades and let declarer make six this time.
