All due respect sir, but the 'one foul' rule (aka, Texas Express) is what eventually killed 9ball...'Two shot foul' rules, make for a MUCH better more challenging, spectator pleasing game !...90% of all the top 9 baller's, from Buddy Hall on down, have always detested the one foul rule !
That's why we are playing 10 ball now, but its basically the same boring game, with, even more chances to hide the cue ball, and get ball in hand !..That's what makes the 'one foul' rule REALLY suck !..Might as well be playing snooker, only the penalties are FAR more severe ! (ie; one snooker usually means loss of game)
Anyone who has played the game BOTH ways knows this to be a fact..It is only the younger guy's, (from about Bartrum's age on down) who tend to think otherwise, simply because its the only way they've ever played !
PS..I am a little biased, but I think it has caused many top players to quit the boring rotation games, and concentrate on the BEST game on a pool table...One Pocket !
