I think against an unknown this play is not so great. Would he bet the turn again with things that don't beat you? The flop is pretty drawless.

He has raised a pfr 3-bettrr on this slightly scary flop he also called 2 cold. I think he has a Q here a lot of the time.

The pot is big, so how likely are players at 3/6 going to bluff /raise the flop with an over, air, a weaker PP?
