100-200 Commerce hand

[exalted]

Its unlikely that he is raising you on the flop for a free card on the turn on such a drawless board - therefore I don't think you should worry about giving free cards, especially since you may be putting extra bets with the worst hand. If anything, you want to see showdown as cheaply as possible.

I think this is a clear fold, especially with your line (which I think is fine) - you cap preflop showing that you do have a premium hand - villian isn't going to raise you on two streets when you're telling him you have AK.

If you really felt this guy was a bluffer, you could check call check call on the turn and river and allow him to keep attacking with a worse hand. However, I think in this hand he has at least AK.
