TPWK against an idiot

[trojanrabbit]

30+3. About half the field remaining. I have about 4700 chips which is above average and the second highest at my table. Villain is the chip leader and is BB with about 5000 chips. Villain seems borderline idiotic: he’s in almost every single pot and has been fairly aggressive, sometimes showing trash, sometimes good hands.

Blinds are 75/150. Everyone folds to me on the button with K9o. SB is sitting out. I make it 450, SB folds and Villain min-raises me 300 more. I call. 1575 in the pot. I have a little under 4000 left.

Flop is rainbow KQ6. Villain bets 500. Hero?
