I am not a fan of a preflop cold call with KQo even in position. If you do want t get in this pot, Make it 3 bets and isolate this guy, and force the UTG to cold call if he wants to play.

If MP2 will bluff all the way post flop, your flop call is fine for inducing a turn bet that you can then raise.

Cap the river, if he is a lag, your hand in this situation will be better than his a fare amount of the time. Despite the time you are beat I thinking caping is a profitable play.
