I'm in the SB. BB is loose aggressive, but not a maniac. Button just sat down last hand.

I have A2off. Can't remember PF, but I either raised, or completed and BB raised and button called.

Flop A 10 J
I check, BB bet, button calls, I raise, BB 3 bets, button calls, I call.

Turn 9, putting 2 of the same suit.
I lead, BB raises, button 3 bets, I ....

What did the button do.

The way you wrote the hand out makes it so difficult to follow.

Either way I think the turn is an easy fold for 2 cold.

Agreed. This is an easy fold.
