Hold-ups can also be used by the defence. Consider playing the following hand in 3NT:
A waits until the second round to win it. You will have no entry to dummy, and will make just one diamond trick! You should consider holding up as a defender when you have the ace of dummy's long suit and dummy has no outside entry. Your partner should signal count in the suit (playing high-low with an even number) so that you can work out how many times you need to hold up.
Hold-ups can work just as well in trump contracts. Consider the following hand in 4 after North oened 1NT. You try covering the T lead with the J, but South plays the Q.
T looks like a doubleton. If you win the A and play trumps, North will win his A and lead his second club to South, who will then lead a third club for North to ruff. This will defeat your contract. To prevent this, you should let South win the first club trick, then win the continuation and lead trumps.
Avoidance plays The hold-up is an example of a play where you are hoping to prevent a certain opponent from gaining the lead at a dangerous time—usually to stop him from running a suit or giving his partner a ruff. There are other situations where you don't want a particular defender on lead. Consider playing the following hand in 4 . North leads the A and switches to a low spade.
K you make the Q, but if he exits in another suit you can set up the long diamond to discard your losing club. On the other hand, if South wins a diamond trick, he will play a club, and North will win another two club tricks to defeat the contract. To minimise the chance of South winning a diamond trick, you should win the ace and king, then play a third diamond, and hope that North has the last diamond. This allows you to make whenever South has a doubleton Q, as well as when the Q is onside. If one of the small diamonds is the 8 (or higher), you can also cope with North holding T 9 precisely—draw trumps ending in dummy and lead the 8 from dummy, running it if it is not covered (or lead up to the A8x and just cover South's card if the 8 is in hand).
Another example:
K x, there is nothing you can do. However, if South has Q x, there is something you can do!
If South has Q x, North has a singleton king, so when you play a club from hand North's king will appear. You now duck this, knowing that nothing North does can harm the contract. If North doesn't play the king,
play the Ace and hope that North has a doubleton. This will lose out when North has all 3 clubs (because he now has time to knock out your spade guard before you set up clubs), but that is less likely than North having the A and South having exactly one of the missing clubs. Even if North did start with three clubs, you'll still have the chance of the diamond finesse and a 3–3 heart break.
