You can pretty much NEVER fold kings in a low stake STT.
I wouldn't play them myself.
I've had a shocking couple of days of bad luck.
in four consecutive MTTs I ran into A,A five times, three times with KK (one of which I flopped a set) and once with AK (and made two pair)
Then in MTT five I had A,A and got beat by K,10 which flushed.
mean while, I'm sat at work during office hours and I'm getting a stream of pokerstars notification emaiol telling me that the wife is winning STT after STT on the same account keeping me afloat.
Bloody Poker!!
