I'm posting quite a lot hands today since I've been more confused than ever. Villain in this hand is somewhat loose and fairly aggressive (~5% pfr).

Preflop: Hero is UTG+1 with A[img]/images/graemlins/diamond.gif[/img], T[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">Hero raises</font>, MP1 calls, MP2 calls, <font color="#666666">5 folds</font>.

Flop: (7.50 SB) 5[img]/images/graemlins/heart.gif[/img], 6[img]/images/graemlins/heart.gif[/img], 8[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets</font>, MP1 calls, <font color="#CC3333">MP2 raises</font>, Hero calls, MP1 folds.
This is a very marginal call...

Turn: (6.25 BB) A[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">MP2 bets</font>, Hero calls.

River: (8.25 BB) K[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets</font>...

I felt he probably check the river if I check and he probably won't raise many hands even if he's ahead. I felt the risk of him raising the turn with a hand that beats me was bigger.

The cons of this play is he could have been playing a draw and check the turn or not calling my river bet if he missed. Also the flop raise/turn bet suggests a strong hand.

What's your line?
