am i overplaying my hand?

[ukdentisto32]

alright, i have played MANY MTT's and have become a descent player at them, anyways, i always seem to go out on a hand similar to this. its the 6-handed $200 1st event of the WCOOP on tilt. we are down to 700 people, the avg. stack is 17k, i have 14k and the blinds are 150-300 with a 50 ante. i have been raising very often and also reraising. generally, playing very aggressively. the villain in this hand has reraised me once, where i folded. and another time where i called and check raised the flop all in where he folded. he is very aggressive though and playing a similar style to mine. on to the hand. sorry no converter

me - 14k in chips
villain - 30k

it is folded to me on the button and i raise JJ to 750, he reraises to 3000...whats my play

IF you say call, and the flop is 984, and he bets 3000, then what is my action?
