Maybe it is weak... I'm not denying that. But there's a trade off of safety to consider.

You're right rilla that 89 is not likely, so that leaves TT. With a guy calling your huge bets like that, you've got to be at least a bit concerned about TT as a real possibility. Any player in their right mind would lay down an overpair to those bets. So tell me, on the turn, what hand could he have?

Maybe it is weak, but at least it's not reckless overagression. A middle set on a board like that is great, I'm not denying, but don't bet the fking ranch on it. The persistence of aggression just seemed excessive to me, especially on players he didn't have a read on. I prefer to build my stack steadily and safely.
