Ugh. Sorry guy, but AK is beating you, AQ is beating you, 44, QQ,KK,AA,A4 and any two hearts are beating you, so is the open ended broadway straight that just got made. In fact the only hands that you're beating right now is K4, Q4 since there aren't many one pair hands that call your raise and those usually have an A.

As nice a hand as KQ split pair is, I'd wanna be confident he was the type to make this bluff before I'd even think of paying another two streets.

My bet would be he was on a draw that just got made since he called, not raised the flop. All the same in the future I'd raise from this position PF. You're KQ suited with 4 folds. If he called it would be with a stronger hand (getting rid of any two hearts as an option)

He's landed ITM which says his caliber of play is probably good enough to assume he's not overvaluing KT. I think you have to jump ship.
