TT is a standard 3bet for me in SB vs. BTN. I am not so worried about limper but he can certainly play a role some of the time. I think the flop bet can be smaller here also but at these stack depths I don't really think sizing up is a bad move. To me the turn is a mandatory bet since a few hands potentially pick up equity in a spot where I block nothing (99, JJ).

What is your reaction when he raises and why?
