$1,000 1 table freezeout. What do you do here???

"I have 5700, he has 4300, pot is 1k. A push feels a little extreme. But if I bet 1500 or less, I know he'll push with any 2. What should I do???"

So let me get this straight.

1) You know he has nothing.
2) You know if you check he'll bet out on the turn.
3) You know if you bet 1500 or less he'll push you all in.

Three options:
1) Dump the hand.
2) Bet 1500 or less, let him push, and since you put him on nothing, call.
3) Push, scare him off and take the pot.
