Pm'ed Gregorio about running a weekly pool problem and got the go ahead so will start off and see how it goes. Pool is a very subjective game so hopefully there will be a decent amount of disagreement but some good general principles that come out and help your game.
I will use the same image template each week but will try and cover 8 ball, 9 ball, and snooker problems, with a brief description of the table conditions, opponent, and a question; leave it up for a week for discussion and then post an answer/analysis and a new problem. I will try and keep up an equal a mix of beginner, amateur, and advanced problems.
Should be every Friday but will probably have some small fluctuations depending on my schedule.
If you have any specific questions/problems PM me and I'll try and build a problem around it.
Problem of the week 1.
First up we have a beginner level problem inspired by one of the threads about asking to get good enough to beat your friends/avoid being hustled.
You are playing 8 ball on a small bar pool table with quite tight pockets against a competent amateur player. Your opponent has broke, but failed to sink a ball. The table looks like this at the start of your visit:
Which set of balls should you take and why?
For more advanced players, which specific ball should you generally be going for first in this layout of balls and why?
SOLUTION
***Brief Disclaimer***
All pool problems are extremely subjective. A player very confident at rail shots or bank shots looks at the table in a very different way to a very solid positional player who loathes tricky pots. This analysis is provided to hopefully open up some concepts people may have not thought about – not to provide any definitive 'right' or 'wrong' answer.
Problem number one sees us in very familiar territory to anyone who plays amateur 8 ball. A small bar table with tight pockets, a dry break, and lots of possible shots/ball layouts to consider. To a skilled player this is a bit of a non question, as both sets of balls are relatively easy to clear, but to an amateur this sort of situation can throw up some huge win or loss problems.
First off, we need to consider the general dynamic of the two positions and try and evaluate which set of balls has the higher EV to take on. In this spot, red has five very easy balls over pockets, two problem reds on the rails, and control over two pockets (albeit ones with relatively little tactical relevance). Yellow has by far the harder opening shot(s), but has no real problem balls, and although not in direct control of any pockets, blocks the black into both lower corner pockets.
Most weak 8 ball players tend to evaluate situations such as this on the basis of taking on the easiest shots first, but this is often a sizeable mistake. In this spot two hard balls on the rail with lots of distance between them and a tough black is a much trickier proposition later on than a single harder shot now (particularly on a bar table with tight pockets that are often miss cut or dead, making rail shots much tougher), and in this scenario you should nearly always be trying to get on the yellow set – even if the opening shot seems considerably harder than the red alternative.
8 ball is not a game of yardage – you don't get paid for potting any ball except the eight – and every frame has to be considered in terms of the set giving the best EV to pot the eight, not any other ball(s). This point is exacerbated by the fact that in 8 ball each ball you pot of your own set makes your opponent's life easier, as it not only opens up the table for them, but also hugely decreases your options when setting snookers or playing safe.
In this frame the hardest shots will come last if you take red, and that means that if you miss you will lose the frame a very large percentage of the time due to the now very hard table dynamic. Note that this is basically the polar opposite with yellow, where the logical balls to take last are both close to pockets, easy to pot from many places on the table, and blocking the black into the two corners (hugely increasing your EV if you miss a yellow before clearing).
In the case of problem one, weak players in such a situation will often pot every easy red and then seem confused when they miss their hard/blocked balls and go on to lose, questioning why they keep losing such frames when they appeared so close winning – usually as they sit and watch their opponent snooker them or simply clear up on the now very open table. They miss the fact that having a 100% chance at a hard clearance is a much worse bet than having a 90% chance at an easy one – a point crucial to understanding which balls to take on at the start of 8 ball games if you are just staring out.
Before getting into the more advanced second question, it is worth pointing out again that due to the crudeness of the diagrams and the difficulty identifying exact angles, there is no one right or wrong answer to such a question, more an opportunity to try and highlight some extra concepts involved in gauging which ball(s) to take on first in 8 ball.
In my opinion the answer in this case is to usually go for the slightly tricky yellow cut back into the middle pocket. With lower left backspin/draw (hitting the cue ball low and to the left as to to the right of the diagram) the white will screw up to leave you a choice of yellows into the left hand corner, as well as opening up the pocket to the only tricky ball of yellow's set – the one just to the left of the middle. Something along the lines this:
This is a simpler shot in the long run than taking the far left yellow to the corner (which requires more draw, or a cushion hit and will often leave a greater distance between cue and object ball/harder angle/less options), or the two cushion option from the middle.
With the middle draw shot, you are left with future very simple cue ball control, as you will rarely be having to be doing much more than a few short range pots/screw shots or occasional rail hits to get onto the next ball with the balls so close to each other and open down the right hand side of the table. Minimising cue ball movement is essential to all long runs of balls if you are just starting out at pool, and this is a classic situation where a slightly technical shot early has the potential to pay a huge simplicity dividend later on, as from then on leaving the cue ball anywhere near the middle of that table should leave you at least one simple pot.
Solution: You should take yellows to gain maximum simplicity and the more solid end game, and you should generally be playing the yellow into the middle pocket with draw and left hand side to maximise simplicity depending on the exact angle/ball placements and your playing style.
