Laying down KK for one bet. Good play?

That's a pretty crappy flop for KK, and it's close, but I suppose a fold is good

But man a minraise preflop??? He calls profitably with any pocket pair and maybe even a suited connecter, what the hell was that?

I can sort or understand it if his stack was like $150, but you guys are effectively 125BB's deep here, a real raise preflop is neccessary, unless you knew for sure that minraising would cause him to re-re-raise with a bad hand

And yeah, I'm not so sure after he makes it $150 you should just flat call. That's a toughie, and I think you created this tough situation for yourself
