I'd thought I'd seen something in either this forum or another forum about the kill button, but now when I go to find it, I can't seem to.

Anyway here's the question...
Over the weekend I was playing at Harrah's in KC, and each pot included with it the kill button. It was only used twice, but the dealer really didn't give a very good explanation of how it was used. I just mucked my junk hands preflop anyway so it didn't matter, but does anyone play the kill regularly or knows the specifics?

BTW Harrah's in KC...3-6...smells like tuna. I raked in a pot with four callers with 8s full of 9s beating a pair of threes, A2, and K10 all staying to the river. I was almost shocked these people still had chips in front of them.
