$500 live sng heads up hand

[DonButtons]

so I got back to miami today, and decided to hit up the casino with my friend at midnight to see how the new sngs are there...

$500 buyin, 10 players.
1st-$2375
2nd-$1395
3rd-$930
Start with 2500 chips except everyone decides to start with less chips like the cheaper buyins for some reason, so we really started with 1500 chips, blinds start at 50/100, and go up every 15 min (you actually get in a lot of hands, with there 2 deck automatic shuffler system) and go up to 100/200, 200/400, 300/600, 400/800, and so on....

So after working the bubble and pushing a ton (sucking out with 36s vs AK on a blind steal, and everyone thinking im a moron, lol) this hand comes up heads up.

Me-11200
Him-3800

Im in the SB with K9s (blinds 400/800), I complete (ive been stealing like crazy up to this point, and the hand before was the first hand heads up and I reraised him when he limped with JJ). He makes it 2400, and has 3800 total. Whats my move. (Ive seen him reraise like this before with k10o before, but check with most other hands like T8s).
