No way I am folding in that spot with KK. I don't know why people call normal raises like that with small pairs. The other night I raised 6x BB with AA and got called by 4 people!
Flop was safe so I made a pot sized bet and got called. Turn brought a second suited card to the board. No strait was possible so the only way I am behind is if someone called my raise with a small pair and flopped a set. I bet the pot again and get called. River is a third suited card (6h) so I just check, planning to call unless the bet is huge. The other person checks too and shows 66. He called me all the way to the river and got lucky hitting his 2 outer.
