... The rule appeared in the 1984 rule book with much simpler wording.
In the 1967 rule book, the rule was in the "official rulings" (decisions on how to apply the rules) section, and it said that the referee could choose to have a "miss" replayed by the offender. In the actual rules section, which was very poorly organized IMNSHO, there was a sentence to the effect that the player should endeavour to the best of his ability to hit a ball on, but that's all.
So, at least since 1967, the official rules have had a "replay the miss" rule of some kind.
Prior to 1967, you just had a "gentlemen will do their utmost to hit a ball on; those who do not are scoundrels" sort of rule with no specific teeth or procedure.
But here is an example of the kind of foul that needs to be covered: The last red is on the black spot but my opponent has left me between blue and brown. I play off the side cushion. I am good enough to hit the exact center of the top cushion, which I do on purpose, but neither the referee nor my opponent can know my intent. In a flourish of showmanship, I remark, "Gosh, the side grabbed funny on the gum!" I play the shot at a speed that leaves the cue ball near the yellow pocket, with no snooker on the very distant red.
What should happen?
Pool has a simple rule in this case. Perhaps snooker could learn something from pool.
