... people often compare long, tough, straight-in shots to shorter and easier cut shots. This is not a fair comparison.
Straight shots ARE easier than cut shots of the same CB-to-OB distance and the same OB-to-pocket distance. Proof can be found in
TP 3.4 - Margin of error based on distance and cut angle.
... if you and others did a simple experiment, I bet your thinking might change. Here it is:
Place an object ball in the center of the table, and place the CB three feet away for a straight-in shot to a corner. Attempt this shot a large number of times and keep track of your make percentage. Then attempt the same number of shots, with the OB is the same place, but with the CB at random angles (maybe up to 30 or 45 degrees) for cuts both to the right and left, still positioning the CB three feet from the OB (along a circular arc) for each shot. Again keep track of the make percentage.
I am confident you will find that the straight shot is easier; in other words, it will have a higher make percentage (unless you have a really serious issue with any of the things below, in which case your results might be somewhat random).
In a way, there is extra pressure on straight shots, because we expect to make them, even if they are long (especially if we have practiced them specifically). In other words, there is no excuse for missing them.
The most common reasons why people miss straight-in shots, especially long ones, are the following:
- Your "vision center" is not properly aligned. If this is the case, you won't perceive the straight line of the shot and your cue alignment properly. FYI, there are tests and drills for diagnosing and fixing this problem on the
vision center resource page.
- You are not hitting the CB on the vertical centerline, creating unintentional sidespin, resulting in squirt, swerve, and spin-induced throw. Tip position is critical on a long, straight shot. The most common causes for having the cue tip off center are a poorly aligned "vision center" and a lack of focus dedicating to checking this during the "set" position of the
pre-shot routine. FYI, there are drills for helping with this problem on the
"finding the center of the CB" resource page.
- Your cue is not as level as possible. If so, the swerve effect due to any unintentional english becomes significant.
- You are not stroking straight. If so, the
stroke "best practices" recommendations might help.
