Villain is 51/18/5 over a small sample. Haven't had yet the chance to pay particular attention to his hands.

BB checks, <font color="#CC3333">Hero bets $12.5</font>, BB calls $12.50.

The turn bet may have been a little bigger, like $14. Nevertheless, if he's drawing to the flush, he isn't getting the pot odds.

The flush card hits and he pushes without deliberation. This is often a bluff, especially from this kind of a villain. He could also have QJ, but it would have been more likely that he would have C/R'd the turn in that case. I'm ahead any lesser Jx but beaten by QJ or any two diamonds.

If I'm OOP on this flop with this action I would consider to shove the flop. Since you are in position its cool.

When he checks the turn, I don't give him credit for a J anymore, especially when he doesnt raise my turnbet. He doesnt seems scared for you taking a free one. This looks alot like a flushdraw to me actually. What type of hand does he bluff the river with that raises the flop an c/c the turn?

I think I have to fold the river here.

Flop c/smallraise + turn c/c smells a LOT like a flushdraw.
And if it's not, then he picked a great spot to bluff, since I can't really see any hands you beat (other than a bluff) that would play it just like that.

I'd typically push the flop and expect a call from flushdraws, QQ+, and 33. Maybe even a few lower PPs.
