2/4 - KK - tough board

[fuzzbox]

2/4 NL - 6-max

I've been open raising a whole lot, but nobody has played back at me even once.

Villain is sitting right behind me on two tables at once. He has previously called my CO raise with QQ from the button, then when a shorty reraised, and I set the shorty in for 100, he pushed for 400 and I had to fold. I have also just seen him call a minraise with 87s, see a flop of 563, pfr hit it, villain called, shorty pushed, pfr pushed and he called.
He's pretty tight, and has some trappy tendencies I guess.

Stacks of about 400
Hero has K[img]/images/graemlins/heart.gif[/img]K[img]/images/graemlins/diamond.gif[/img] in the MP
Villain is MP+1.
