Playing TP against Maniacs

[lanyi]

The villain is this case is 41/21/2 a real maniac. Plays any ace, any suited cards any cnnected cards (even off suit) of any rank and any pair. My question is whetehr I am over valuing my TP against this type of player when he shows this much of continued agression.
