Hero Bets, Villain Raises, Hero 3-Bets, Villain Calls with Q[img]/images/graemlins/spade.gif[/img] 8[img]/images/graemlins/club.gif[/img] (No reason to hide results, I had the nuts for 13BB)

Heckler: You got lucky
Hero: Who are you kidding? I had like 20 outs on the flop
Hecker: No way you could have 20 outs..
Hero: No I was exaggerating a little...checks PT...it was really only 12.

I love people that don't know what the hell they are talking about [img]/images/graemlins/grin.gif[/img]

I also love having 12 outs on the flop, 11 of them nuts. I still like the 3-bet on the flop. Villain has shown they know where the preflop raise button is on monsters, so I am confident I'm not against AA or QQ here. I just feel the villain is unlikely to improve and if I improve I'm dominating.
