I LOVE 66!

Just a second ago i get into a 3.30 KO tourny and get pocket kings on the third hand i make a substantial raise like 4X BB. I get one caller. He checks the flop and i bet again a large amount (the flop is like Q 8 9) he takes his time and calls. turn is rag card again i push he takes his time and calls. I figure at this point he has AQ. so, thats good for me river is 6. he checks i push the rest of my stack in. he calls and turns over 66. all, the while i'm playing at a .5/.10 cash game i've been playing at it for about 40 min. (staying at around the $2 that i've bougt in for) i decide i am going to play one more hand and leave. I am dealt KK. I have been playing tight aggresive the whole time. half the table calls so i decide to push all in (i know stupid move with KK) figuring i will collect all their .10 and be on my merry way. every body folds but the donk who turns up 66. and im thinking it cant happen again. but u know what it did. right on the flop. so, twice tonight in the span of twenty min. i have lost with KK to 66!
