Back when I had Eurosport (the TV channel), they used to broadcast a lot of snooker. It was sort of mesmerizing, two players trying to put the ball in a place where the other couldn't do anything useful with it, then one would make a mistake and the other would clear the table (not all the time of course, but I was always impressed by how one small mistake would decide the round like that).
Have never tried to play snooker myself, but have seen the snooker tables in pool clubs. And they are huge. So I stick to regular 8-ball when I play some sort of billiards.
