Sng heads up situation

[The_Bends]

Live 9 player Sng, down to 2 players.

Stack sizes (aprox)
Hero 12000
Vilian 6000

Blinds 200-400

Pre flop
Villian raises from sb to 1500
Hero calls with 4h5h

Flop (pot 3000)
2d 3h 9c

Hero checks, Villian bets 1500 (has 3000 left), hero re-raises all in, villian calls

Read on villian is decent player, guarenteed to be aggressive in this situation, raise pre flop could mean anytihng from a pair to nothing. He would automatically bet the flop but I would expect an all in with a stong hand (he's afraid of being outdrawn)

My justification? I think he probably has a couple of high cards and that my outs are all live and include the 6 remaining cards to give me a pair. I estimate I am 50:50 to win the hand if he calls.

Thoughts?
