My favorite pocket pair would definitely have to be 7's. Mostly because 7 is my favorite number, but also because I have more memorable winning hands with 7's more than any other pocket pair.
I don't have one favourite pocket pair, because I can play various, it depends on the deck. Sometimes I lose AA against three or four of a kind, so it is usual situation, cause we have dispersion.
my pav hand is of course aces lol but problem with them is its hard to fold
so really pocket 9s or less is best and safest hands to play being is easier to fold when you know your beat
My favorite pocket pair is KK. It is because highest equity. Why not AA? Lets consider. Most players likes to call with just Ax hand, so if you have KK, usually will be more players which will put something to pot.
