Your thinking is sound, especially if he was raising the table too often, but the amount a tourney is often reflects the type of play you will see. A8 call off.. absolute donk. But if it's only $2... why not. Play those .25 tourneys if you don' t know what I'm talking about. With a maniac like that (if indeed he was but I think a call of with a8 qualifies as a maniac) you are best off to either trap him, or go in with a more quality hand than qj. He's going to call wiht anything, so you might as well go in the race ahead. If you really want to get him, call pre, and shove the flop. Better luck next time.
