When the board gets progressively more scary

[topspin]

Button is a moderately tight player who hasn't gotten out of line in the two orbits we've sat together. SB is your typical loose-passive calling station. MP1 is a rock.

Preflop: Hero is BB with T[img]/images/graemlins/heart.gif[/img], T[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">3 folds</font>, MP2 calls, <font color="#666666">2 folds</font>, <font color="#CC3333">Button raises</font>, SB calls, Hero calls, MP2 calls.

My standard play is a 3-bet preflop, but with a limp from a rock and a raise by a tight player, I wussed. In retrospect I'm thinking with 2 extra players padding the pot it's an easy 3-bet, no?

Flop: (8 SB) 8[img]/images/graemlins/spade.gif[/img], 9[img]/images/graemlins/diamond.gif[/img], 5[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, Hero checks, MP2 checks, <font color="#CC3333">Button bets</font>, SB calls, <font color="#CC3333">Hero raises</font>, MP2 folds, Button calls, SB calls.

Turn: (7 BB) T[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(3 players)</font>
SB checks, <font color="#CC3333">Hero bets</font>, Button calls, SB calls.

River: (10 BB) J[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players)</font>
SB checks, <font color="#CC3333">Hero bets...</font>

I bet planning to call a raise on the river.
