Charles Outred was intrigued by this difficult deal from a team-match. West leads 9 against your 5 contract won by dummy's A as East follows with K. You successfully finesse Q and cash A, West discarding 4 (odd or encouraging). When you exit in , West discards 7 and East wins with 6. Plan the play if
1. East exits with T
2. East exits with K.

If you feel brave, please have a go, at single-dummy, but I'll post the full deal in a day or two, when you can try it at double-dummy. I found it difficult, even with sight of all 4 hands :(

[North hand corrected, in the light of CyberYeti's post]

N has 14 cards which is why nothing adds up when I try to work out the other hands

Looks to me the other hands are something like:

Spoiler


In which case 5 is a pretty wild bid, so now to work out what to do with that.

Charles Outred discoveed the hidden depths of this beautiful deal.
Cyberyeti has correctly reconstructed the East-West hands.

West leads 9 against your 5 contract won by dummy's A as East follows with K. You successfully finesse Q and cash A, West discarding 4 (odd or encouraging). When you exit in , West discards 7 and East wins with 6.

Plan the play if
1. East exits with T
2. East exits with K.

You may want to correct one of your posts, in the OP he exits with the diamond 10, in the last post the heart 10 for case 1.

As CyberYeti correctly points out...

If East exits with T, you reduce to the ending on the left, where the last trump fixes West.

This is a simple squeeze without the count

Again, CyberYeti points out the solution.

If East removes your entry to dummy by returning the K, you come down to the ending on the left.

West is now squeezed when you play 5 to dummy's 6, if West pitches a , you play on s, if he pitches a , you ruff out his remaining and end-play him in s.

What we might call a shape-shifter squeeze

I like to simplify deals to high-light the key-points :)
e.g. I make South declarer and s trumps.

But I often introduce errors when I try to do so. Sorry.

CyberYeti sussed it out, in spite of my mistakes.

I'm aware I could have simplified it more (as on the left).

West leads 9 against your 5 contract, won by dummy's A as East follows with K.
You successfully finesse Q and cash A, West discarding 6 (odd or encouraging).
When you exit in , West discards 7 and East wins with 6.
Plan the play if1. East exits with T2. East exits with K.

It's a lovely hand. Thank you for posting, Nigel. Just out of interest you describe the first squeeze as a simple squeeze without the count. Not that I'm any expert on squeezes, but isn't this some form of stepping stone squeeze? And wasn't the count rectified when you gave up the trick?

Please advise me if I'm wrong (which probably I am).

It's not a stepping stone, a stepping stone is where you force an opponent to give you access to a winner in a hand you can't get to yourself because you don't have a card in the suit.

A criss cross is slightly different again in its standard form A, Qx in one hand Qx, A in the other, looking to catch the guy with Kx, Kx where which ace you cash next depends on what he discards, and it operates with no more tricks to lose.
