[Floundering]

I was playing in a tournament on PS against 19 people where 1st prize was a paid trip to Monte Carlo.
I think I was 5th out of 12 remaining when this happens:

Seat 2: 2 (820 in chips)
Seat 3: 3 (3090 in chips)
Seat 4: Villain (2605 in chips)
Seat 5: 5 (3130 in chips)
Seat 6: 6 (2070 in chips)
Seat 7: Hero (2660 in chips)
6: posts small blind 50
Hero: posts big blind 100
*** HOLE CARDS ***
Dealt to Hero [Ah Ks]
2: folds
3: folds
Villain: calls 100
5: folds
6: folds
Hero: raises 200 to 300
Villain: calls 200
*** FLOP *** [Jd Qs Jh]

What would you do? The next thrilling part of this hand will be forthcoming shortly...
