"the blinds are $300 and $600 with a $50 ante. The game is ten-handed, so there is $1,400 in the initial pot. You have K4o in the small blind and your stack is $9,000.

If everyone folds to you and you move in, you are laying about 6.5:1"

Can anyone tell me how he came to the 6.5:1 number?
What am I missing?

(If it is so simple, and stupid to even ask, I apologize)

You're risking your entire 9000 to win a pot of 1400. 9000/1400 is approx. 6.5 to 1.
