Anna Kournikova a tennis player and also a poker hand
Firstly this of course a very pretty tennis player from russia. In Texas Hold em Poker, Anna Kournikova refers to the starting hand AK. You may think now that the hand is only called so because of the initials. But there are more similarities as just the initials. Anna was under the Top 20 in the world for a long time, but she never managed it to win any single tournament. She became a international word star because of her beauty, even though she was never on of the best players.
With the hand AK is is similar. it looks very attractive and is one of the best starting hands in texas holdem. But many players are blind from the beauty of AK and overplay the hand very often.
