Ace on the flop when holding Kings

[stodin]

I seem to be in this situation alot recently. I am holding KK, make a 4,5 or 6 xBB raise get a caller (or 2) then see an Ace on the flop. Is it straightforward fold to a raise or should I sometimes represent a bigger Ace? I tend to mix it up a bit and without tracking software I am not sure what I am winning or losing here. It certainly seems that I am folding more often than not to the raise. I am playing micro stakes 0.02/0.05 and 0.05/0.10 on Pokerstars which has plenty of people who would call a 6 xBB pre flop raise with Ace rag. Any stats from GaF to advise me in this situation?

Re: Ace on the flop when holding Kings I'll try and find some stats later on :ok (if I forget - feel free to remind me). My (statless) thoughts though - If I bet pre flop and an Ace comes on the flop, and no-one has bet before me, then I will usually cbet - I feel I have to represent the Ace if I raised pre flop, However, at microstakes where your opponent is possibly more likely to have a (raggy) ace himself, and is less likely to fold with any connection - a less aggressive approach could be argued. If you cbet and get played back at, then you should probably never put another cent into the pot.
