20/40 PP HU vs. Stuck_Again make a desperate call?

[DrGutshot]

We have been playing for about a half hour 3 handed. I seem slightly overaggro at this time, and he probably hates me for 2 outering him earlier. For those of you who don't know him, he's like 40/30 when 3 handed and is too aggro postflop. What do you put him on here? Is this a busted draw often enough for me to call, or is this downswing getting to my head?

He openraises on the button (he's ~55 att.tosteal), I 3bet from the BB with K [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/diamond.gif[/img], he calls.

Flop comes A [img]/images/graemlins/heart.gif[/img]T [img]/images/graemlins/heart.gif[/img]3 [img]/images/graemlins/club.gif[/img]

I bet he raises I call.

Turn comes 4 [img]/images/graemlins/diamond.gif[/img]

I check he checks behind.

River comes 9 [img]/images/graemlins/club.gif[/img]

I check he bets...
