Villian was loose-weak and already lost a pot against me where he limped (with AJs) and I pushed - he called. After I just checked and flopped an OESD my money is going in right?

I am always scared pushing in these spots especially at $3.4 and with 84 [img]/images/graemlins/wink.gif[/img]

EDIT: Man, I am really still a little bit drunk. I just have a Gutshot. [img]/images/graemlins/smile.gif[/img] Okay now i guess check/fold the flop but my question is whith what kind of hands are you pushing here PF?

PS: I hope this makes sense...
