$550 Live Tourney. 165 started, about 65 remain, top 18 pay. Blinds are 200/400 with 75 ante.

Hero is in BB with 6500 chips. Thinking maniac villain (who has raised 40%+ pots in last few orbits and shown good/marginal hands but hasn't called down anything stupid) is in cut-off and has Hero covered.

All fold to villain who makes it 1600 to go. Button and SB fold to Hero. Hero has 4c4s.

What's the action? Push? Fold? Call?

Edit: Hero's image has been solid, perhaps even tight due to being completely card dead the last few orbits.
