??? -- My intent on the flop was to raise 1 bet back to me. The raise by button was worrisome but gave me an opportunity to protect. After it's capped on my left, what's the plan of action for the turn? And are there any arguments against the flop 3-bet?

I think there's a good chance MP has AA and button could well have you beat as well. I'm looking to see a showdown as cheaply as possible here.

If you check the turn and it goes, check, bet, raise, call, 3 bet, cap then I think you have a safe fold. Anything less and I'm seeing a showdown and expecting to lose. Betting the turn is pointless.

bet the flop.

as you played it, check the turn and fold for two cold. otherwise call down.
