[doubleas]

UTG raises to $15. It is called in 2 places and hero calls in the SB. Maniac/wierdo BB reraises to $40. Folded to hero who calls with [Q [img]/images/graemlins/club.gif[/img] J [img]/images/graemlins/club.gif[/img]].

Flop is J [img]/images/graemlins/heart.gif[/img] 7 [img]/images/graemlins/heart.gif[/img] 7 [img]/images/graemlins/club.gif[/img]. Hero checks, BB bets $25. Hero calls.

Turn is 3 [img]/images/graemlins/club.gif[/img]. Hero checks. BB bets $100. Hero calls.

Flop is 8 [img]/images/graemlins/club.gif[/img]. Hero bets $300 (flush). BB reraises all-in for $300 more. Hero calls.

How do you play this differently if at all against a proven maniac/wierdo.
