1. Standard.

2. With QQ I'd bet, maybe JJ too, but with TT here it looks like he has QQ/JJ that will call a turn bet, or a slowplayed AA/KK/AK. AQ and other stuff would likely bet the flop. So yeah, c/f here.

3. Bet this river for sure. As played I think a river raise is in order, looks like he is squeezing value with Ax or something.
