Just busted a 10K guarantee in 5th place and not sure if i made the correct decision.

Payout. 1st 3.2k, 2nd 2.4k, 3rd 1.7k, 4th 1.1k, 5th 770

MP. 11BB folds
CO. 30BB shoves
BTN 10BB folds
SB. 7BB folds
BB. I have 15BB and have JJ

Everyone on the table is a solid reg except the CO who definitely a big fish. He is only pot cbeting, overcalling 4bet shove with A7o and shoving very wide. I would guess about 30% of Hands.( Unfortunitely my Hud isn't working on this particular site so i don't have excact stats)

Was it a mistake calling of my 15BB stack with JJ considering the big payout jumps. (Villain had KJ and busted me but don't wanna be results oriented)
