I know not of what you speak? I've heard of the rule, but I can say I've NEVER played 3 foul wins in my entire life. So, my answer had nothing to do with 10b. So, I'm inclinded to agree with you, I don't like that rule at all. I'm speaking of where safties come into play the most with league players, which is 8ball.
I have played 3 foul wins in league. 9 ball.
My buddy suggested I safe my opponent. I thought he meant 3 safe him.
Which I did and won.
Afterward my opponent came over to where I was sitting pushed me in both
shoulders and said. Just shoot the fvking balls.
Knowing just how well he liked safeties. That was what he saw from me.
Every time.
Actually his kicking game improved. I was just helping his game.



Another opponent successfully kicked out of 8 consecutive safes. A very
good kicker. But all the kicking took him out of his game.

If there is a 3 foul rule. By all means use the safe. And when you think you
have him, play one more for good measure.
I would not endorse a 3 foul rule in 8 ball. Much too easy. But if it were there,
I would use it until the various captains made a change.
