jj, middle position, m = 6

20+2 MTT, 100 entered
Blinds 100-200
My stack = 1800, M=6

Relatively loose table, folds to me in middle postion holding jacks - should I push or make a standard raise to 600 or 700?

My thinking is that I push because jj is vulnerable and I dont have enough chips to get away from the hand, even if high cards flop. But the problem with this is that a caller will get to see all five cards and maybe catch on the river - this is what happened by the way, late postion called with kq and spiked a queen on the river.

So should I raise and push the flop no matter what hits or should I just push pre-flop?

Any help appreciated.
