The Nut Flush Draw

[onegymrat]

Commerce 20/40 game. Table is terrific. Two limpers to me on the button with A [img]/images/graemlins/spade.gif[/img]7 [img]/images/graemlins/spade.gif[/img], I limp along. SB and BB calls. Five to the flop.

FLOP: Q [img]/images/graemlins/spade.gif[/img]8 [img]/images/graemlins/diamond.gif[/img]4 [img]/images/graemlins/spade.gif[/img]

SB checks, BB bets, EP calls, MP (tight player raises), I'm next to act. Call or reraise?

All comments welcome. Thanks in advance.
