on 2+2 forum I saw someone venture out that it's 4.4% that some1 has AA when you have KK at a 10-handed table.

they wrote:
When you have KK heads up, there is a 6/1225 chance the other player has AA (6 ways to make AA, 50*49/2=1225 possible starting hands left after you get KK). 10-handed, a good approximation of the math, although technically incorrect, is that 9*6/1225 = 54/1225 or 4.4% chance someone else has AA.

u gettin screwed i guess
