[TomBrooks]

1st Shot at 5/10. Pacific. Full ring, 9 players. 1st Orbit.

Preflop: Hero is UTG with A[img]/images/graemlins/heart.gif[/img], Q[img]/images/graemlins/heart.gif[/img]
Hero Raises, fold, MP calls, 3 folds, Button (named BwnTrout) ReRaises, SB and BB fold, call, call.

Flop: (5SB) 7[img]/images/graemlins/diamond.gif[/img], 7[img]/images/graemlins/club.gif[/img], A[img]/images/graemlins/club.gif[/img] (3 players)
Hero checks (?) intending to checkraise, check, check.

Turn: (2.5BB) Q[img]/images/graemlins/club.gif[/img]
Hero Bets, MP Raises, Button folds, Hero calls

River: (9BB) 9[img]/images/graemlins/club.gif[/img] (2 players)
Hero checks, MP bets, Hero calls (??)

My questions:
1. Should have I counted on Button to bet this flop?
2. Should I have called the river?
3. Anything else?

If you are checking this river it should probably be with the intention of folding.

I think you played the hand fine. Going for the flop checkraise is fine, since you likely have the best hand and the preflop 3 bettor will usually bet this flop every time no matter what he has. Turn play is standard. And on the river I can see why you called getting 10-1 pot odds. It seems obvious that the turn aggressor has a flush, but I still think this is a call online getting 10-1 simply becuz there are so many idiots out there that will pop this turn with Ad6d and still bet the river hoping you will fold. With no read I think it is ok to call this river, I have called many rivers in seemingly hopeless situations like these online and to be honest I am suprised at how often i did win.
