Interesting KK situation

We can find a fold here, right?

Villain is 20/17/3

PokerStars No-Limit Hold'em, $0.50 BB (5 handed) Poker-Stars Converter Tool from FlopTurnRiver.com (Format: FlopTurnRiver)

SB ($37.25)
BB ($49)
Hero ($57.40)
MP ($98.25)
Button ($98.10)

Preflop: Hero is UTG with Khttp://www.flopturnriver.com/phpBB2/...es/diamond.gif, Khttp://www.flopturnriver.com/phpBB2/...iles/heart.gif.
Hero raises to $2, 1 fold, MP raises to $4.5, 2 folds, Hero raises to $13, MP calls $8.50.

Flop: ($26) 7http://www.flopturnriver.com/phpBB2/...iles/spade.gif, Qhttp://www.flopturnriver.com/phpBB2/...es/diamond.gif, 5http://www.flopturnriver.com/phpBB2/...iles/heart.gif (2 players)
Hero bets $15, MP raises to $30, Hero finds the fold button since QQ, AA pwn, JJ doesn't raise like this PF, and KK splits, and AK doesnt raise the flop.

I would pay it off somewhere around 100% of the time. Think about flatting preflop too

Uhhh... 5 handed too...

I felt this, but he's either being really retarded or extremely confident in his hand.

Would love to know how often he 3-bets and how often he folds to 3-bets. This is a tough spot though, I'd usually just pay it off and call it a cooler if it goes against me.
