West leads ♥5 [edited after a wholly justified complaint from matmat], four, queen, ace.

Neither of your opponents has six cards in any suit. Therefore, claim your contract before you make a mistake. But just in case, state your line of play.

Not sure whether this is really BIL material, but it was actually dealt at the Young Chelsea this evening, and it is a cute hand.

I don't see it. Is there really a 100% line when East starts with a singleton spade and KQx of hearts?

Yes.


Here are two hands for East:
1. x KQx Kxxxx 9xxx
2. x KQx Kxxxx Qxxx

For the first hand, declarer must play a club before touching trumps. For the second hand, declarer must NOT play a club before touching trumps.

For the first hand, declarer simply ducks the club exit, and LHO is still endplayed.

If they return a spade, we duck from dummy, and ruff in hand, draw the last trump, and have to guess which minor to exit I believe.

Nice to see a textbook one come up... Shame I don't read lol

I also don't see a line that handles both of these.

Unblock ♦A (as well as ♠A of course) immediately. Exit with trump, if they play a trump back play a diamond and overtake with the queen. Next thing: whoever wins the diamond trick will have to put dummy on lead or break the club suit.

Can't they cash the ♦K before playing back a trump?

I still don't understand how it is 100% if you just play on trumps. Say you do and RHO wins the trick. He returns ♣s, which you have to duck to prevent them setting up a stack of clubs. After winning, LHO plays a spade to your ace. You draw more trumps if you like but eventually play ♦A and ♦. RHO wins this and plays another ♣ which means you are going down with LHO having KQ♣ and RHO K♦ and KQ♥.

You could still make it on this layout by cashing the ♠A before exiting in trumps. Then LHO is endplayed as soon as he gets in with the first ♣. So it looks like it is 100% as long as there is no ♠ ruff?

Right, that's where I got also, Jorrit. As long as spades are no worse than 4-2, it's always home I believe. If spades are 5-1, then you have to duck the eventual spade return and guess which minor to endplay someone with, although a diamond is more likely to work.

Perhaps David couldn't imagine a singleton trump lead. Indeed if it was a singleton trump lead the opening leader perhaps should be immediately shot?

Clearly all 2-2 trump breaks have a 100% line. So do all LHO-RHO 3-1 trump breaks. It appears to me that not all LHO-RHO 1-3 trump breaks are a 100%. So I will wait for David to explain why those are 100%

If East has x KQx Kxxxx 9xxx there is no endplay.

club return ducked to west.
spade return ducked and ruffed in hand.
West comes down to all clubs, East just matches your pattern. You're hosed. If you exit a diamond East wins and pushes another club through you. If you exit a club West just continues clubs.

We can't see a 100% line. We're obviously not good enough for the B&I forum.
