JJ against big stack

[vetman81]

UB $30 MTT

About 65 players left, top 20 get paid, I am in about 20th with 4250. I get dealt JJ UTG+1, UTG folds, I raise to 400 (blinds 50/100). Big stack (10000+) in MP2 reraises to 1300. I had seen him do this a number of times trying to buy pots, but had folded to aggression, but all of those times were postflop.

So there is 1850 in the pot and it cost me another 900. If I call I will have 2950 left. I can just as easily fold and move on. Does anyone push? What do you do here and why?
