I know I'm going against conventional wisdom but here's a couple of points to think about:Well, then, I'll continue to the next logical sentence from your statement, better players prefer tighter pockets because, to them, it makes the game more pure, less slop, more skill, which, then ,logically is just saying that the tighter pocket is one factor that makes the better player a favorite. Unless someone has a different definition of what makes a player "better" than another player.
You're playing Jason Shaw. He's spotting you 200 to 50 (huge spot). Who's likely going to be at the table more to take advantage of loose pocket? Who's ever at the table more has the greater advantage, right?
Second scenerio - you need to play Shane a race to 9 even. Would you feel you would have a better chance playing on a snooker table? I think the answer would be yes.
