The maniac is a loose-aggressive player – he calls and raises frequently with not strong enough cards. When at the table there is one maniac, undoubtedly, all other players are going to have profit. When there are more, it is necessary to play very carefully and your play should be very flexible. When you are in early position and after you there are many maniacs, you should enter the game only with very strong hand. If after you there is only one maniac and you are the dealer, even if you have mediocre cards, you still have a very good chance to win. Depending on you cards, your style with maniacs should change from passive to extremely aggressive – with strong hand you can and you should raise or re-raise; with mediocre cards, the better choice for you is not to confront them since it is very dangerous.
