As I said, I saw him make bad plays throughout. I know he's 3betting me light there because I've allowed him to get away with it on several earlier occasions. This was my first 3b or 4b at all...I had raised plenty of hands, shown the ability to fold to his 3bets. His style was incredibly exploitable. Way passive with strength, 3- or 4-betting weak, and huge 2xpot overbets generally on the turn. Every bet he made at the FT committed him to the pot. A6 is well ahead of his range here, so that's not the issue to me.
