Dubious play on all streets

[topspin]

Played about one orbit so far. MP3 is the sort who likes to see a flop with any two. Button was pretty quiet so far.

Preflop: Hero is CO with Q[img]/images/graemlins/club.gif[/img], Q[img]/images/graemlins/spade.gif[/img].
<font color="#666666">5 folds</font>, MP3 calls, <font color="#CC3333">Hero raises</font>, <font color="#CC3333">Button 3-bets</font>, <font color="#666666">2 folds</font>, MP3 calls, <font color="#CC3333">Hero caps</font>, Button calls, MP3 calls.

Flop: (13.50 SB) 6[img]/images/graemlins/heart.gif[/img], 5[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players)</font>
MP3 checks, <font color="#CC3333">Hero bets</font>, Button folds, MP3 calls.

Can't really check-raise to protect here, and if Button has an A I'm toast. But check-calling down seems horrible and I might still be ahead here, so I bet.

Turn: (7.75 BB) 3[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
MP3 checks, Hero checks.

Well, the only draw on this board hit already. Pot is big and I want to show down my hand, so I check planning to call a bet on any river card.

River: (7.75 BB) 8[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
MP3 checks, <font color="#CC3333">Hero bets...</font>

What, no bet despite me being weak? Well, maybe a worse hand will call ...
