I was seated at a 100 NL table with a huge fish. He was -$1100 over 200 hands, and that's with getting lucky a bunch. He was playing 75/7 with a 3 Bet of 15%, often min raising 3 Bets in position against middle-late raisers. He'd also limp and then call freakishly large raises., (limping for 1$ and then calling $15 dollar raise).

I'd seen him call $125 preflop with A9 off, call $100+ after flopping middle pair, call his entire stack off with an inside straight draw. The only way he doesn't call flop/turn bets is with complete air and no draw. Has also called all-in once with two pair on a four flush board. He was also shoving all-in on scary rivers fairly wide, especially if preflop raiser showed signs of slowing down.

Is the best strategy against this person, to isolate him with 3 Bets when possible, and then keep the pots small-medium unless you have very strong hands? Or since he is willing to call all-in with baloney, it is worth playing for stacks anytime you have an overpair or TPTK.

I'm just sort of wondering... Playing for stacks everytime you got a leg to stand on is definitely profitable against this guy (as evidence that the players averaging > $100 from him), but its high variance... many players lost hundreds with him catching draws and flopping two pairs. On the other hand, playing for stacks only with two pairs or better, seems less profitable but certainly less variance.

I have 20 buy-ins for 100NL... if I had 50 buy-ins, I'd be much happier playing the high variance version... but with 20 buy-ins you could easily lose $500 to this guy in a few hands playing for stacks with over pairs and TPTK.

Thoughts?
