Pockets = someone else has pockets

Well, personally I think that if you have pockets, there is a much higher chance someone else has pockets. I have never had pockets without someone else having pockets (some people might have low pockets and fold but still).

I guess it makes sense, you get 2 of the 4 possible cards instead of the 1 of the 4 which adds to someone else having 2 of 4 since there is still 4 in the deck instead of 3 :P
