When you have a choice of equal cards, which one do you play?
This is a fairly complicated area which needs more than 1 video, but I will give a good starting point
Play the top of equals - This is a common idea, and helps disguise your holdings.
Playing the Ace may keep west guessing about who has the King, partner or you! There are actually some reasons to play the King (play the card that the opponent has already denied - leading the Queen denies the King), but I will look at that in further videos.
