Flopped straight flush how do I get max value?

[ThePershore]

Couldn't get history to work so from memory:

10 handed mtt, around 80 left, 200 or so runners. Hero was top 5 in chips but justed bluffed of around t6,000 chips flat calling on button vs late pos raiser and hammering flop and turn but getting CRAI and had to fold. That was around 15 mins ago and have tightened up since then (no raises in a few orbits). So my image is mid-way between TAG and LAG.

Villian is average, plays semi-tight but not a nit or anything - tho he has been fairly quiet.

Hero is MP1 with ~ t12,000
Villian is BB with ~ t10,000

Blinds t150/t300 no antes.

3 folds, Hero raises to t750 with 8[img]/images/graemlins/club.gif[/img] 9[img]/images/graemlins/club.gif[/img], 5 folds, Villian thinks for ~ 10 seconds and calls.

Flop Q[img]/images/graemlins/club.gif[/img] J[img]/images/graemlins/club.gif[/img] T[img]/images/graemlins/club.gif[/img] (Pot t1,650)

Villian hesitates and after 10 seconds bets ~ t900, <font color="red">Hero calls(?)</font>

Turn 5[img]/images/graemlins/diamond.gif[/img] (Pot t3,450)

Villian hesitates again and bets ~ t1,650, <font color="red">Hero?</font>

Pot is now t5,200, Villian has t6,700 behind and it's t1,650 to you....

Flat call again or small raise to get more money in?
