UB Sunday 200 - Tough Decision, or is it?

[Small Stakes]

A buddy of mine was in his first Sunday 200, and an interesting hand came up. 125 players left, started w/ 610, bubble is at 80 players. Blinds 200-400 50 ante. Avg stack is 11k. Full table. Hero is BB Villian is in 5th spot after the blinds. Villian has been aggresive and willing to make moves. Hero is normally a rock, but he went on a rush from 2-16k in the last hour so his image is probably fairly loose.


Pre-flop
Villain has 19k and min raises to 800.
Hero is in BB w/ Qs Qc and smooth calls.

Flop Js Ts 9s.
Hero checks
Villian bets 1200
Hero raises to 3600
Villain flat calls

Turn Js Ts 9s 4h
Hero bets 4000
Villian min raises to 8000.
Hero ??????

The pot is 21,500. You have about 8,000 left w/ an overpair/ open ended straight flush draw but its 4000 more to call which is half your stack.

Please let me know your action/ and give an analysis of all streets if neccesary. I will post my thoughts/results in a few days. Thanks
