I think people might be using different definitions of "parallel english" in this thread. Here is the definition in my
online glossary, which I think is the most common and standard use of the phrase:
parallel english: aiming technique when using sidespin where the cue is placed parallel to the line of aim for a center-ball hit (with no sidespin) resulting in no compensation for CB deflection (e.g., for shots where swerve is expected to cancel the effects of squirt and throw, resulting in no net CB deflection, or where the amount of resulting pocket cheat is acceptable).
I think some people are instead interpreting "parallel english" to mean:
Based on experience, instinct, and/or intuition, place the cue in the desired stroking direction, with the tip already at the position needed to created the amount of sidespin desired, and with the cue already pointing in the direction necessary to compensate for squirt, swerve, and throw. In other words, don't line up center-ball first and then use a pivoting method (like
BHE, FHE, or some combination) or a
swooping stroke to arrive at the necessary line of aim to use the amount of sidespin desired. This is how pretty much all pros and great players aim when using english; although, this should not be called "parallel english" unless the shot
Regardless of how you determine the necessary stroking line of the cue when applying english, even if completely intuitively, the cue must be pointed in a certain direction for given shot to send the OB into the center of the pocket. For example, with a short distance between the CB and OB and/or with a firm shot, BHE (with an appropriate bridge length) will give you a good line of aim. If you use true parallel english with a shot like this instead, it will be way off (especially for larger amounts of sidespin). However, if you aim intuitively and bring the cue into the necessary line of aim with no pivot, that is fine, but if you don't have the cue in the same direction created by the BHE approach, you won't pocket the shot (unless the pocket can be cheated significantly).

Dave,
I totally understand everything you're saying here. That said, I'm not so sure that everyone does.
As to your definitions, I would dare to guess that nearly everyone that uses english in a non pivoting manner would disagree with them even if they are technically correct.
I know you have done your best & are doing your best to appropriately 'define' certain methods but it is extremely difficult I would think to define what is done unconsciously by the subconscious.
PJ went so far as to say that there is no such thing as parallel english & you define it as only a method of cancelling squirt & swerve.
The thing is you &,I assume, PJ are starting YOUR parallel from a given line, the center line of a no english shot that would pocket the ball dead center in the pocket. Well that is not how everyone sees it & even the tight pockets can be cheated.
It depends with what part of the cue ball one is using to align & to what. Is it the contact to contact point but a bit thick because I intend to use the spin the throw it. Or ...is it contact to contact but a bit thin because I intend to use less swerve & more squirt to thicken the hit. And, Yes, again pockets can be cheated, even the very tight ones.
For example, a long nearly straight but with a slight cut shot can be lined up to MISS the pocket & then a parallel shift to THAT line can be made & then stroked to throw the ball just inside the point to pocket the ball or the squirt can be used depending on the 'imbalance' of offset & speed/swerve.
I could never play to the level that I am going through all what you have defined to apply english. Apparently the OP & others could not either. But I did use english rather well even as an unafraid & perhaps unknowing 13 year old.
I hope you can see my points & remember I have some physics education while many others do not.
I agree with you that the definitions & vernacular can be confusing & are at times the root source of 'disagreements'. It would nice if everyone spoke in a precise & specifically defined manner. BUT if something has been called something for decades upon decades it is very difficult to change it no matter how much more technically correct the change might be.
I had trouble with CJ's TOI using a parallel shift until he said something that 'made' it work. Some or many may not be making a parallel shift when that think that they are & the reason may be that the cue is conical & not tube like with 'parallel' perimeters.
We 'all' know what BHE & & FHE & even a combination of both at the same time are. That said parallel english is a bit in la la land. Then there is that 'primal' or primary pivot where the cue rotates around instead of pivots on.
So...it's not BHE & it's not 'true' parallel, so what is it?
Anyway, Best Wishes to You,
Rick
