K♥-7-A-2
Q♥-5-6-8
J♥-3♦-T♣-K♣
Now what?
Do you assume that the person who has 7♥ is unlikely to have 3♣ and play the top 2 ♣ or do you assume that giving up the ruff-sluff in hearts could only be done with 3♣ to promote? Do you cash one more club and cross to dummy (in ♠ or ♦?) to protect against JT tight with West at the slight risk of a ruff?
