bb vs a maniac opening...

[thirddan]

live 9/18 game

villain here is a drunk maniac...will open with anything and bet to the river with anything, but will also give endless action with nothing incluidng calling bets with J hi and similar, so he is probably never folding A/K hi heads up...

Hero is BB with QhJh

Preflop: villain opens on the button, folded to Hero who calls...

Flop: 5 2 5 with one heart (2 players, 4sb)

what is my plan for the hand?
