I almost puked when I saw this river. After some thinking, I couldn't figure out any hands he has that make sense here. AK-AJ bet or raise before the river. JJ raises PF, 66 is unlikely as I have one of them. A backdoored 7 would be so so sick. Thoughts?

Preflop the stack sizes are right? So its only $58 back to you to be allin? I probably man up and find a call here getting that kind of price.

Also is his tendency only to shove light, or to shove and call light?

Probably has 7 [img]/images/graemlins/spade.gif[/img]x [img]/images/graemlins/spade.gif[/img]. I'd just fold.

Villain seems really bad and aggressive enough to bluff this river with missed spades among other crap.
I think it's a call.
