This is not as easy as it may seem.
Your play should be dictated by which opponent you think will get in next.
If you think it will be West, you win with the Ace and you still have a stop in the suit with West on lead.
If you think it will be East, you should duck two rounds and then win with the Ace. With East on lead he won’t have any more cards left in the suit unless the suit broke 4-4 all the time.
If you don’t know who’s likely to be on lead, you’ll have to make a good guess!
