Top 2 vs Overpair

[thabadguy]

My kings just ran into aces, and i folded preflop, so I am a little pissed off.
I have about $10k
BB has about $4k
Raiser has about $8k
(Raiser is an rich old country club kinda guy, plays a lotta golf and poker for fun, dosen't care about money at all. He is the kinda guy who if you want you can bluff easily, and if u want, u can get to call easily. Will make a small pf raise with any 2 and says "its to get more money in the pot" I have made him laydown a few hands before where he was waaay ahead. The ideal opponent according to me.)
Next hand I see on the button is 4h7h.
MP with about $8k in front of him raises to 40.
I call like the tilting idiot i am ,BB calls as well.
3 to the flop Flop is 4 7 2 rainbow. Miracle flop right?
BB checks. Raiser bets $500, (thats how he plays overpairs...dosent want any action after flop).
I raise to $2k(Comments about this raise?).BB folds. Raiser calls.
Turn is Kh(still rainbow)
He bets $3k. My action?
Please no comments about the pf call. Probably the worst call ive ever made.
