Pass - (1♣) - 1♠ - (X)
Pass - (2♥) - 2♠ - (X)
Pass - (Pass) - Pass
First double was high-low. (Either a normal negative double, or a forcing hand.)
Second double was penalty.
The lead is the ♥3, fourth best, to the King.
East takes the ♣A and returns the ♣10.
Do you use the King or the Jack?
Is it obvious?
What are your considerations?
I would appreciate many replies, even if they are redundant.
Thanks in advance.
