Maniacs

[nutbag]

It all depends on a maniacs preflop raise for me here. If it's greater than 4 times the blinds, I'd follow the push in strategy. Calling a maniac with non-premium hands is a horrible move in a tournament in my mind. You're putting yourself, and sometimes your whole tournament on the line against unknown cards. And unless you have a high pocket pair or AK, it's too risky to put in more than 20% of your stack(of course this number varies depending on time and number of player left); so in this case there's nothing to do but push when you have a big edge. But I disagree with pshab on the lower raises, if he is more of a light raiser 2-3 times the bb, then you have much more leeway with your cards(especially in late position when you act after him. Here you might only be risking up to 10%, and pushing on a suitible flop would be advisable(and much less risky comparatively).
