For those of you who are interested in snooker and/or statistics, I have
made available a website which is the result of my research into the game
of snooker (and tennis, by the way). You can find it here:

I think there is enough there for the time being to keep you occupied; you
can compare players throughout the careers, plot up to 5 players at a time
and also plot the winning probability for any pair of players.
