I have QQ, raise 3x, some donk who's been calling every pot with crap calls. (I won't state the stakes here, but he'd won about double his buyin getting lucky, then lost all of that plus half of his original buyin.. so now he continues to play every pot). Flop comes J 9 3 rainbow. I'm shortstacked, sick of this guy, so I push it in. Turn comes a blank, river comes an Ace. He showed A6 offsuit. How do I deal with donks that call pre-flop raises and post-flop enormous bets with crap? I just don't understand it and it seriously pisses me off.
