Sorry I'm old school. When I learned to play pool 50 yrs back and if your did an intentional safe People called you names, didn't want to play with you anymore Or you were waited for and taken out to the back ally for a good black eye or 2. BUT now it's apart of our game and people take great delight in to leaving you snookered. Even if they can run out they still safe you just for the satisfaction of seeing you squirm. If anything that takes away from the game and the way it's suppose to be played.As far as jumping I have found that people that can't jump or won't invest in a good jump cue or take the time to practice jumping wants it abolished. As long as intentional safeties are allowed. They deserve to have a shot and if they are good enough to jump and make the shot so be it. Sorry if I offended anyone.
