Hero starts hand with $950 in his 2nd orbit at the table. In my first orbit I tried 3betting from the bb after mp raise and co calls. mp calls and co jams AI so I fold which makes my play look like a squeeze. It's the second orbit now and I pick up KK from UTG1
Villain 1 utg2($900) - young player. Seen him raise his co and button and instafold to a 3bet pre.
Villain 2 mp1($1000) - jock looking white guy just sat down. He has a state championship football ring on and has played one hand.
$5/$10 No Limit Hold'em Live- 10 players

Pre Flop: ($15.00) Hero is UTG1 with K

UTG folds, Hero opens to $40, UTG2 3bets to $140, MP1 4bets to $270 folds to Hero????
What is the best line to take? I'm not folding. Do I 5 bet? If so what's my bet sizing? Am I doing this for value or for information. Do I fold to 6bet? Do I ever flat the 4 bet to try and trap? Should I just jam AI since there's already $465 in the pot? What's the best way to max value? Any advice would be appreciated
