Playing live, 9 handed UTG raises, i call KQs, 1 other caller, guy from SB 3 bets, UTG flats

do you call this with KQs? 100-200bb deep. everyone is unknown

it used to be, at least for me, i assume the standard play from them and wont play back my self until i see evidence to do so. so i would normally assume utg raiser is gonna have a tight range, and i assume the SB 3 better would have jj+ , ak.

so i fold to the 3 bet.

i used to be a regular in the stars/ftp 2550 games. havent played in a few years. just started watching these sauce videos, seems like he would almost certainly have called that. which i dont understand. what flop am i hoping for? am i prepared to stack off if i flop a top pair? call once? twice? seems like no situation is great for me so i would think folding is perfectly standard.

what do you all think, would you have called this and why?
