in SNG's, i like having one of these around.
in a 9 person SNG the the other night, maniac-boy cleared out 5 players bringing it down to 4 players. up to that point, i'd played one hand (and doubled up) and then just stayed out of the way. because of maniac boy, it's down to 4 and the blinds are still low. at this point, us 3 non-maniacs attacked his giant stack, and within ten minutes, he was out, and didn't hit the money.
we all commented how nice it was for him to clear the field for us.
