Hi everyone, this hand came up in the Stanford vs. Cal match on Saturday afternoon. Cal's declarer was actually in 3NT, but the challenge here is to play for twelve tricks.

Whatever you play from dummy at trick one, righty plays the ♦6. Also, righty will show Qxx of clubs, returning the jack of hearts upon winning the queen.

On the second round of diamonds,

Spoiler

righty discards a heart

. On the first five clubs,

Spoiler

lefty follows to the second round and discards a small diamond, a small heart and a small spade, while righty follows to the third round and discards two small hearts

.

Edit: fixed auction.

Just cash dummy's last club and play for a triple squeeze against west, which will operate anytime he has one spade honor. Nice endposition, I hope you did well in the collegiates!

I think we need to cash ♦A before running clubs for the squeeze to work.

No, as long as dummy has the ♠K as an entry it will work.

right.

Here's the full hand.

It plays down to something like the following position:

Scoring: IMP

On the penultimate club, West is squeezed out of a spade. On the last club, declarer discards the idle diamond, and West is guard squeezed. Since West must keep the diamond guard and the spade honor to guard against the finesse, she lets a heart go. This sets up the diamond king for a positional squeeze against East.

I think that makes this a compound guard squeeze.

I don't. A compound guard squeeze is "a squeeze in three suits, in which two suits are stopped by both opponents and the third holding requires a defender to retain certain cards to prevent declarer taking a winning finesse" (Encyclopedia of Bridge, 6th edition).

On this hand only West had a diamond guard, so this is just a double guard squeeze, with the unusual feature that keeping ♦Kx opposite a void makes up for squeeze card's being in the same hand as the diamond menace, and means that the eventual double squeeze is non-simultaneous.
