I know what Endy's talking about. I'm a 7 and I would much rather play a 5 than a 3. I know I'll beat the 5. But against the 3... 2 losses can happen to anyone on a bad day, the balls could lay funny and I'm forced to take the clustered ones, the 8 could be hanging in a pocket right in front of one of my balls, I could drop the 8 early (happens to the best of us), the 3 could slam the balls on the break and sink the 8, and the 3 could really just be a 4 who occasionally gets out in 2 innings.
With all that said, I was super upset and hated the handicapping at first, but now I think it's the fairest system, certainly better than our local Valley league's system (which I also play).
I think the bar-rule of 'take whatever drops on the breaks' is interesting. I hate it when it screws me, and logically it should screw a weak player too, but it really is an equalizer because the better player will breaking more, and occasionally won't be able to shoot what he wants.
So I'm in favor of helping out the weaker player but I also agree that this rule + the slop teaches them bad pool and lazy habits. They SHOULD learn not to hit at warp speed and how to make the right choice after the break.
If I could change one rule it would probably be the 8-on-the-break-wins rule. That's not only unfair and gives a stupid reward for something that was mostly luck, it doesn't help the weaker player, it may even favor the stronger player because that's the person who will be breaking more, and that's the person with the skills and knowledge and solid break who knows to try to hit the 2nd ball on the rack etc. I think it leaves the lesser player with the wrong impression, that pool is about luck.
APA LO: The reasoning about slop being allowed in 9 ball is that when there's only 1 ball on the table to legally shoot and several potential blockers, the odds of getting hooked are very high. So players are constantly forced to kick (compared to 8 ball). The idea is that if you kick a ball and luck it into a pocket, you should get rewarded. Asking the player to call the kick is too demanding, most of us are just happy to hit it. Also if you accidentally sink a kicked ball without calling the pocket correctly, you directly helped your opponent, you essentially made one his balls for him. So it wouldn't seem fair if you make a tough kick and sink a ball, but he gets to step up the table with 1 less ball to run.
I find it doesn't affect 8 ball much so I can live with it not being changed, but occasionally it's stolen some matches from me, the most recent time in a best of the best event which really steamed me.
