My thinking is the third heart came off, I think I am pretty much prepared to stack here with TPTK, assuming that if he called my 3 bet with AQ AJs, hes getting taken along for a ride. I want to bet the turn to protect from the 4th heart from hitting and giving him a free win. What line would you take? Check for pot control in case I'm up against a set or a hand like KQ of hearts or bet to protect?
