Am I a maniac for playing this hand like this? I've been in a lot of situations like this lately where villian called down and showed me (for instance) a weak ace or queen, and the recent frequency of this suggests to me that I may be getting overly aggressive with middle pocket pairs on boards with big overcards. This is one case where it worked, but I think I might have gotten lucky and scared MP1 into folding the best hand.

If he check-raised me on the turn, I'd have to fold. If he only called and checked to me on the river, I'd probably just check it through.
