With a missed AK/AQ/AJs here is my usual line:
If the flop is rags rainbow I am c-betting.Depending on the opponent and turn I will either check or bet.
If the flop is highly coordinated I may decide to check then ESP if up against multiple loose calling happies.
If the opponent is a solid TAG and plays back at me and I have Ace high I may call and check fold the turn then.
