3/4 pink

[bluenose1940]

I've said before that I find this thread really fascinating. Some really interesting comments from avruga at #74 above. I have a number of snooker books that I often refer to but none of them refer to the maths element of the game, I must admit that applying mathmatical theory to the game has never crossed my mind but, when you think about it, it is a pretty logical approach really. I have heard it said that maths can be applied to pretty much everything in life and, if it will help me with my game, I'm ready to learn. One of my major problems when playing. is working out the angles to get out of snookers. I am wondering if there is a really good theory book available that covers things other than stance, griip etc. Is there a book that would explain the makeup of the table (not the construction) that would give a better insight to angles relative to the travel of the balls. I hope that I have explained myself ok here.

Angle of incidence equals angle of reflection. If it's a 3 cushion escape you have to draw in your mind how all these angles affect each other to arrive at the OB. However, some cushions will also add some throw on the ball, a bit like running side (especially off the first cushion), when the CB is played at pace at an acute angle I think, so this has to be factored as well. I think this is to do with the CB not squeezing the cushion evenly over the contact area. Maybe J6 can comment?

Would feel really strange if I got down on the table and said to myself I better hit that ball 1/4 or 1/2 it just wouldn't enter my head.

Because an exact 1/4, 1/2 or 3/4 doesn't exist. The danger is assuming it's 75% contact for 3/4 when it's really 73% etc and then you miss. Approximating angles is suicide. Judge each angle individually. After a few years, one should be able to subconsciously recognise all the angles from 0 to 90 degrees anyway, banking all the angles is the way forward.

theres also the table to consider with a responsive steel block table thats squares up off the second cushion.. i would like to explore this a bit later using the grid, the colors on there spots, and plane ball striking. its surprising how often the similar patterns keep coming up, so you can get quite good at exscaping with the understanding of a handful of shots

but if you dont know what a 1/2 ball pot is then who cares right? your also likely to be the kind of person who misses shots and never looks into the reason why. and thats okay

it does on the 3/4 ball shots on this thread, but yes its the patterns that keep coming up that a player memorises
as for the 73% i think most pockets will accept that approximation even on mid range shots, and after jawing a few youd soon have to tidy up your line if you wanna win the frame in one visit

Ray Reardon's book Classic Snooker, he uses what he calls his 'rectangle theory', where he visualises smaller rectangles within the large rectangle of the table when escaping snookers and plays the cue ball along those lines.
There are many diagrams in the book that explain it.

I use this method and can escape from all sorts of snookers using three or four cushions quite well, although the one cushion escape I find really difficult.

I use the rectangle method as well and get out of some duessie snookers
as you say it does not seem to work well on some one cushion snookers

3/4 ball 1/2 ball 1/4 ball have nothing to do with contact, it's coverage of the object ball.

hi avruga,
thanks for your input. theres quite a difference between 2/3 and 3/4, 2/3 being inbetween 3/4 and 1/2. have you tried these shots yourself on the table, and do you see this pic as 2/3?

Thanks for the reply.

Just to clarify you've said that the 3/4 pink is set up by putting the white on the cushion half-way between pink and blue. I've tried this on the table - sighting with a ghost ball and playing the shot as disciplined as I can at 3/4 ball and it just doesn't seem right. When set up like this the correct potting angle is between 1/2 ball and 3/4 ball to my eye.

If you swap the 4x4 grid (between pink and blue) on your diagrams for a 3x3 grid it works perfectly with the 3/4 ball shot at 2/3rds of the way from pink to blue and 1/2 ball at 1/3rd of the way.

It's difficult to show here but with a bit of trigonometry you can show that this is correct. If anyone is interested I could probably sketch it out.

[jrc750]

I'm with Leo on this, just seems pointless thinking is this a 3/4 or half ball shot, just get down and pot the thing !!
If you are half decent you will just know the potting angle, all this just seems totally unnecessary

can you give a brief explanation to the rectangle method?

[itsnoteasy]

This thread isn't about potting balls, if you have a pot and can say this is near enough a 3/4 pot ( as an example) on the pink ,it doesn't have to be spot on, but you will have some knowledge of the patterns the White ball will make round the table, that's what is being shown here, don't get hung up on the potting.
On another note how else would you describe what is trying to be shown? By saying just hit the ball in the right place and the White will go here or there? You have to have a way of setting the shots up that you can repeat and learn to recognise, I'm not really a half ball player etc, but it isn't half handy being able to recognise them and I have used these shots and knowledge of the patterns lots of times in games already.

i would be more than happy to get into it and see some of your diagrams, but id like to know what you see as a 3/4 ball. the image above, how do you see it?

http://www.thesnookerforum.co.uk/boa...aching+Reardon
this old thread had links to the series of Ray Reardon sessions and in part 13 snooker he explains using parallel lines to visualise the path off two or more cushions, these pairs of parallel lines make the sides of the rectangle
Unfortunately the youtube vids are no longer working
anyone have access to them?

back to the thread of what people call 3/4, 1/2, 1/4 balls
