I think you're ahead most of the time here, but shouldn't be because you won't get called by a worse hand. If he really hit a ten and leads the turn, why wouldn't he bet the river? I think if villian is CR happy, then he would hit it on turn and then push river. In reality, I feel 99 is the most likely hand and he doesn't think you have a ten at the beginning of the turn (or he was just making a stab at the pot since you're most likely to have overcards rather than an overpair).

Anyone disagree?
