no need to raise the turn

10/20 limit must have taught you more than a healthy disrespect for money.

well here's my thought process....

I thought he had air on the flop and turn based on the timing of his bets and the fact that they just didnt make sense - why would he smooth call with TT+ preflop? So I floated the flop, thinking he would stab at the turn oop again, and I repopped him there thinking that would take it down. Instead he minraised. But even the minraise smelled fishy (I didn't get why he would leave himself with $50 there). So I really thought/convinced myself that he had 33-77 or air... then again he easily could have had A8, 89, 2x, a slowplayed overpair, etc.
