Stack size problem?

[wtf5]

Sorry live game...dont no a converter i can use for this.

Me around 7,500
villain covers me

blinds 75, 150
7 man, quite early MTT tourny

Villian is quite fishy but only plaeyd about 30 hands with him. limped then Called a raise from the button and a call in early position (he limped too). Doesn't seem very aggressiev but plays a few pots.

UTG limps
me (J,J) i raise to 600
Fish in Co re-raises to 2000
UTG folds

What do i do?

Its 7 man and even though hes not very aggressive i think he could do with this do with A,K Q,Q-A,A and perhaps A,Q and 10,10 though not certain.

Shoving: doesn't seem like a great idea...I fold all the hands that i beat and only get called by A,K that i beat.

Calling: Seems better than shoving even though im oop. I'll haev invested a 1/3 of my stack but villian will be in a big pot with me with hands that i beat.

Folding: Don't think im folding J,J 7 man to a re-raise but thats just me...if u think i should fold tell me (and why i should!)

Ok so i think calling is best and i will check fold an Ace high flop but what if its a good flop?

good flop: Q,x,x x,x,x etc (x = card lower than a jack)

raising: again not a great plan on a good flop. he will probably fold hands i beat and shove with hands that beat me. If you plan to bet-fold, again that is horrible. U can't invested nearly all ur chips in a tourny and then fold. I'd have 10 BBs which will not dead is a disasterous outcome.

Check RAI: better i think. I get a cbet from A,K and 10s and A,Q. Even though i still losing to a high pair i think that it earns more money when im ahead than when im behind.

Folding: ehh why are u around if u are check folding or raise foldign a good flop and have lost 1/3 of ur stack?

So anyone agree with me that my best course of action here considering the awkward stack sizes is to call and then check fold a bad flop and check raise allin a good flop?

Thanks for any input!
