In situatinons like this i have no idea where i stand, so i prefer to make it one bet at each round. That means if he bet i call, if he checks i bet.

Against a TAG you vill loose more than 50% percent of the time so a flop fold is best, but aganst a maniac you gonna win more than 50%. It seem like a passive play but against maniacks i think its wery profitable.
