Set on flop, danger on turn

[Secret Squirrel]

Live game. Buy-in $125. 9 on table in re-buy period- first hour. Blinds 25/50.

Stack sizes similar as early in tourny- approx 3000.

Hero has 5 [img]/images/graemlins/diamond.gif[/img]5 [img]/images/graemlins/spade.gif[/img] and is in MP1.

6 limpers including BB and SB see flop.

Pot: 300t

Flop: J [img]/images/graemlins/heart.gif[/img]9 [img]/images/graemlins/heart.gif[/img]5 [img]/images/graemlins/club.gif[/img]

Checked to Hero in MP1 with 2 to act after.

Hero Bets 200.

3 callers including BB.

Pot: 1100t

Turn: A [img]/images/graemlins/heart.gif[/img]

BB leads out with 600.

Hero...???

Reads: loose table: Mostlike to chase draws and play Ax in any position including BB.

Any help appreciated.
