Last week, a hand like this turned up in a Scottish Cup match.

It might have come straight out of a squeeze textbook

Against South's 6♠ contract, West leads ♥10.
(0 or 2 higher honours)

Plan the play.

It seems a preparate hand as cards sequency or not ?

For my own amusement, when I have the time, I simplify and standardise layouts by doing things like

• Removing distracting pips (I could use x's instead).
• Weakening the North and North-South hands..
• Making ♠ trumps or the squeeze suit.
• Making ♥ the threat against RHO, if possible.
• Making ♦ the threat against LHO, if possible.
• Keeping ♣ as the communication suit. if possible.

This helps to avoid deals that are almost identical except for cosmetic variations, It also makes it easier for double-dummy analysis

This is like B. Romanet makes explaining double squeeze initially : squeeze card ♣ 7, LHO menace ♥ 9, RHO menace ♦ 8, double m. ♠ 3 with A as winner and 2 for communicant card using always the same cards to present endings (unilaterals controlls with red Jacks - orientation referred to squeeze card).

Nice, a compound squeeze.

Duck the heart and hope it wasn't a singleton. If East returns a club (or diamond) win in hand, play 3 rounds of trump, cash ♥A, and play 2 more rounds of trump.

After the opening heart lead, a club switch, ♥A, and 5 rounds of trump pitching a heart from dummy.

Play the last trump and you have to guess what West had kept guarded.

If West abandons diamonds, pitch a club and lead a club to the king which squeezes East in diamonds and hearts.

If West abandons clubs, pitch a diamond and cash ♦K and return to hand with ♦A which squeezes East in clubs and hearts.

JohnU has the right idea.

Duck the ♥ lead. Win the return. Cash 5 rounds of ♠s, discarding a ♥.
RHO must keep a ♥ guard, so he can guard only one minor (say ♣)
Cash the top cards in the minor that you guess East abandoned (say ♦).
Now, reduce to a 3 card ending as above.
Finally, the last trump executes a double squeeze without more guesses.

This preliminary squeeze determines the variation.
Textbooks tell us that this mutate theme is common in compound-squeezes.

It is always better, when is possible and you visualized, polite ending chashing winners. These ones have two situations (in this case): double (=comunicant) menace in diamond and unilateral in club or double m. in club and unilateral in diamond plus Jack of heart for a balanced double squeeze with 3 cards.
