Overpair vs a maniac!

Is this standard play or does anybody have an other approach?

against a maniac:

cap the flop 100% of the time. why didn't you -were you planning to raise a turn safer than the 6[img]/images/graemlins/spade.gif[/img]?

raise the turn, call a 3bet and call the river.

Against someone *much* more passive, consider laying down on the turn.

No, this looks fine, as long as you were planning on raising most turns. This turn card is as bad as they get, though, so calling down is fine.
