A difficult river

[tessarji]

Bellagio 15-30 Sun afternoon.

I haven't played many hands at all, but when I have they've been straightforward. I certainly have a TAG image. The villain is a young player who's also playing TAG, the most noteworthy hand I can remember he check-raised the flop with an OESFD, hit the straight flush on the turn and then just bet it home.

I raise UTG with Q [img]/images/graemlins/diamond.gif[/img] Q [img]/images/graemlins/club.gif[/img], folded to the villain on the button who 3-bets, I four bet, he calls.

Flop: J[img]/images/graemlins/spade.gif[/img] T[img]/images/graemlins/diamond.gif[/img] 5[img]/images/graemlins/spade.gif[/img]

I bet, he calls quickly.

Turn: 9[img]/images/graemlins/heart.gif[/img]

I bet, he calls again.

What's the best thing to do here?
