As South, neither side vulnerable, you are dealt:
What is your opening bid?
Partner responds 1. What is your rebid?
Perhaps you could have bid differently after partner's 3 preference, but keeping things simple, you end up in 5 as shown. What is your plan on the K lead? The defense plays 3 rounds of spades and you trump the third one.
Draw trump (they are 3-2). Take the A and throw a club on the K.
Play the Q and A and trump a low club with dummy's K.
