5/5 PLO: noob bluffing in 600BB pot

[Jamougha]

Villain is pretty aggro and has been kind of tilting from loosing 5 buyins, mostly HU. When not tilting I suspect he's pretty decent. Still I don't know how to play this game so I can't really tell.

Pot Limit Holdem Ring game
Blinds: $5/$5
3 players
Converter

Stack sizes:
Button: $1496
Hero: $3162
BB: $396.70

Pre-flop: (3 players) Hero is SB with J[img]/images/graemlins/spade.gif[/img] 7[img]/images/graemlins/diamond.gif[/img] 6[img]/images/graemlins/spade.gif[/img] 5[img]/images/graemlins/diamond.gif[/img]
<font color="#cc0000">Button raises to $20</font>, Hero calls, BB calls.

Flop: Q[img]/images/graemlins/diamond.gif[/img] T[img]/images/graemlins/spade.gif[/img] 6[img]/images/graemlins/heart.gif[/img] ($60, 3 players)
Hero checks, BB checks, Button checks.

Turn: 5[img]/images/graemlins/spade.gif[/img] ($60, 3 players)
<font color="#cc0000">Hero bets $45</font>, BB calls, <font color="#cc0000">Button raises to $150</font>, <font color="#cc0000">Hero raises to $555</font>, BB folds, Button calls.

Here I figure he always bets a set on the flop and he can't really raise with Q5xx so he must also have spades with some additional outs. Like 87ss.

River: A[img]/images/graemlins/diamond.gif[/img] ($1215, 2 players)
<font color="#cc0000">Hero bets $1215</font>,

Figure he never has KJxx after flop action so I rep straight wrap w/ spades or a thin v-bet from a set bc I hate cc and figure he will fold stuff like AT w/ spades? 921 for him to call.

Good or bad?
