Never fold KK preflop, right?!?!?

[FireStorm]

4th bet isn't always AA anymore, obviously. Back then, probably. Here, probably.

One has to wonder, if you can't reason for a fold here, apparently you never can unless you're insanely deep. I can't imagine one buy in facing more heat preflop.

I think this is a fold, I don't think MP is doing this light against the SB's move, or with AK often enough to justify getting your stack in. I really don't think he ever has QQ here either.
