1. No, if W has 3 to the K, he will wait a long time for the third round if you play if you play ♠AQ and he ducks, declarer now switches to clubs and the contract is just cold, but if W wins the second one and makes declarer ruff a heart he's sunk. 2/3 diamond K just loses, E wins and plays a heart, what now ? Q♠ wins because if E ducks you cash A♠ then rumble clubs, if he wins, you ruff the heart with the A, cross to the J10 to draw trumps then play clubs.
