Way ahead way behind or no...

[Elaboration]

Pokerstars tourney 30+3

I've been active and aggressive, but not overly so. Villian has not played a ton of hands and has been pretty unassuming.

Blinds: 25/50
Hero: t2500
Villian: 2700

Pre-flop

2 limpers, folds to Hero in the CO with AKo and I raise to t250

sb calls and BB and the two limpers fold.

Flop: (t675)

K Q 5 rainbow...sb bets t300

AK, AQ, 55, KQ and maybe KJ or JTs spring to mind.

How would you play the rest of the hand?

-Thanks-
