medium strength hand against maniac

[aggie]

Villian is 58/29 and very aggressive post flop after 60 hands. He's been calling down when he's got any piece (although he hasn't had to do so in a big pot). This is the second time i reraised him preflop. A few hands ago he called a reraise and then check-folded the flop.
