The reason I don't want to raise is because playing 10max to make money means you play BIG pots. This guy already plays big pots, and he's not going away. If I raise, I'll be committed to stay through it. The only hand I'm afraid of right now is AQ, since I don't think he'd play a set this way (he'd bet at least pot with set/two pair, he had a set last orbit) AQ is in his range, but only barely, since he can raise with a lot of different cards.
At this point in the hand, I'm putting him on twenty and up that involves a queen (QT, JQ, QK, AQ, or maybe some kind of pocket pair, I will admit that some kind of Ace is not out of the question), since I don't think he'd play those this way on the flop.
I'm not saying I didn't raise, but these are my arguments as to why I wouldn't want to, especially looking back.
