A most interesting hand from a thrilling finish to the Israeli Teams Championship on BBO vugraph Saturday. As South you are in 4♠ after East opened a natural 1♣. You doubled and no more bidding by EW.
The lead is ♣8 to East's ace; a club is returned to your king and the 3 from West, indicating a doubleton.
How do you proceed from there? Three lines seem possible:
1) Knock out ♠A.
2) Take a heart finesse. If it wins, lead a spade up.
3) Heart to the king and a spade up.
What do you fancy?
