big pots are for big hands (200bb deep NL600)

[Pog0]

The game has just went 3-handed a couple rounds ago. Hero has been sitting silently for those few rounds as well as for a bit before then.

28/20 (48% steal) raises to $18 on button.
39/16 calls in sb.
Hero looks down at a monster and pops it to $80 with 9[img]/images/graemlins/diamond.gif[/img]6[img]/images/graemlins/heart.gif[/img]

Based on my inactivity, button's steal % and the dead money, this seemed like an opportune time to make a profitable preflop bluff.

Button folds.
SB calls (wtf?)

Flop ($178): 2[img]/images/graemlins/heart.gif[/img]5[img]/images/graemlins/heart.gif[/img]6[img]/images/graemlins/spade.gif[/img]

SB leads out for $110. Hero calls.

Turn ($398): 9[img]/images/graemlins/spade.gif[/img]

SB checks, Hero bets $320, SB raises to $640

$320 to call, hero has $685 total (covered).

notes on SB are that he is somewhat tricky, although my examples only show small bluffs (like bets flop, checks turn, bluffs river). His turn c/r % is 6. No similar situations in my notes.

Help me. The board didn't look like a healthy one to trap on.
