Turn could be a tiny bit bigger but it's not a huge issue. I'm not going to fold to a mini-raise on the turn. He can probably do this with any ace, a 9 obviously, and maybe something dumb from time to time. Also, he has a full stack and there are still aces left in the deck. On the river it's tough when he is a passive player. I can fold to even a 75% bet here fairly easy. Against a half pot I probably just call to chop a lot and lose sometimes to a 9. Fold certainly isn't terrible though.
