WO double hemlock
I'm bumping this thread to point out that Kasidokostas has had to change over to playing left-handed because of tremors in his right hand. Here is an article about it: http://www.kozoom.com/en/billiard-carom/news/filippos-kasidokostas-the-wonderboy-is-back.html
He plays close to his former level with only six months of practice with his left hand.
I wonder if a world title has ever been won by a player who switched hands.
...that would be marvelous.
