Middle stage of tournament

Blinds 600/1200
UTG (50250) limps
UTG+1 (52545) raises to 3200
Player folds
Hero (29000) Calls with QcQd.
BTN Folds
SB Folds
BB Folds
UTG Calls

Flop (12240) : 4s8s9d
UTG Checks
UTG + 1 bets 9180
Hero shoves

What would be the best line of play ? What range can i put the player on? Could i have played this any differently? I lost the hand as the UTG +1 had KK.
Should i have re-raised pre and folded to shove in order to define original raisers hand better?

Any insights would be helpful.

Thanks in Advance!
