LONG POST WARNING (Part 2): How to execute a slip stroke; nuances & bennies
[...continued from Part 1...]
What does moving the grip on the back swing do?
As mentioned above, it adjusts the cue to "fit within the known-straight practice stroke range of motion," without any uncharted / unexplored territory. That is, you practice stroke to verify your stroke is straight, then you adjust the cue forward (through the slip-and-regrip on the final backstroke) so that contact with the cue ball "happens" through one of those normal practice strokes. There's no stopping at the cue ball during the practice strokes; then when you're ready to fire, you enter uncharted / unexplored territory when the cue tip contacts the cue ball and beyond, as happens with a conventional stroke. (I hope this makes sense? I'm trying my best to describe it.)
How in the heck do you get your hand to move back?
I described that above and in previous posts, and others have as well, but I'll summarize again:
* During the back stroke of cue delivery, while your grip hand is still forward of the 90 degree angle to the cue (forward of perihelion, still in the FINISH range), pinch the shaft of the cue with your bridge hand slightly.
* While pinching the shaft with your bridge hand, release your grip slightly and slide your hand back several centimeters / a couple of inches. You need to do this while your hand is still forward of the perpendicular to the cue (i.e. in the FINISH range), so that as you're sliding your grip hand, it is "falling away" from the cue and minimizing friction with the grip area. In effect, you're trying to slide your hand back while the cue is "suspended in mid-air." (It really isn't -- gravity is always acting on the cue -- but you're doing this quick enough during the cue's initial "free fall" to catch it later during the regrip. That's why it's imperative you do this while your grip hand is forward of perihelion in the natural arc of the stroke -- still in the FINISH range -- because the natural
downward arc of your grip hand traveling backwards sends it towards the floor and away from the cue, minimizing friction with the grip area, allowing the "slide" or "slip" to take place. The cue, in effect, starts its free-falling while your grip hand travels backwards and downwards -- albeit the cue only "falls" several millimeters -- to catch up with your grip hand later, during the regrip.)
* Once you've "caught" the cue during your regrip, you release the "pinch" in your bridge hand, and continue stroking the cue backwards, still in the normal range of your practice strokes. The "pinch," by the way, is a slight exaggeration. You don't want to have to "think" about pinching the cue, nor introduce any movement in your bridge hand; rather, you want any traction in the loop of your closed bridge to temporarily hold the cue during the slip-and-regrip. You may find that you don't have to do anything at all in the bridge hand -- if you've a cue with a forward balance (i.e. the balance point of the cue is located significantly forward, say, in the forearm area of the cue), you probably don't have to do any pinching at all -- the forward balance of the cue probably places enough friction in your bridge to hold the cue.
* Then, execute your forward stroke, just like your practice strokes. You can insert a pause, if you like, at the very limit of your back stroke, just before beginning your forward stroke, a la Buddy Hall, Cliff Joyner, or Allison Fisher. (Your choice, really.) Since you've repositioned your grip hand backwards on the cue, when you go forward through the full range of motion of your normal practice stroke, you end up contacting the cue ball in the process -- SURPRISE!
In effect, you've "adjusted the cue" so that the contact with the cue ball now happens within the range of motion of your practice strokes, without any uncharted / unknown territory like that which occurs in a conventional stroke when one "stops" at the cue ball during the practice strokes.
Years ago I saw Allan Gilbert play. He had a huge slip, 3, 4, or 5 inches. The cue did leave his hand in a big way or so it seemed. I walked in to where he was playing, put my cue together which had a rubber grip. He looks at it with a frown and said "Take that thing off and learn the slip stroke. All the greats used it."
Allan was correct -- you cannot (or not at least with some great difficulty) execute a slip stroke with a rubber grip. Not without doing some herculean opening of the grip hand (completely releasing the cue) and snapping it closed later during the regrip, which would throw some jarring motion and significant yaw in the process of cue delivery. A rubber grip is not designed for that anyway -- as a 3C player you already know that.
A slip stroke is best used with an Irish Linen grip, since Irish Linen is inherently slippery, never tacky, and
almost never sticks to the skin of the hand (unless there's some kind of patina on the Irish Linen that gives it some sort of traction). This facilitates the slide or slip backwards, with minimal interference from traction. A slip stroke *can* be accomplished with a leather grip, but the slip-and-regrip process would have to be exaggerated a bit (i.e. releasing the grip a little more than normal) to compensate for leather's increased "grippy" feel over Irish Linen. I'd found that it's difficult to execute a slip stroke with an unwrapped cue, unless one uses some powder or corn starch on his/her grip hand (but then again, that might be due to my own situation with hands that perspire a bit).
As for learning the slip stroke "because all the greats used it," there's two sides to that story. Yes, many of the greats used it back in the day, but don't forget, playing conditions were different back then -- nap cloth back then instead of worsted cloth like today's Simonis and variants, tighter pockets today, better quality balls today, better quaility rubber cushions today, better lighting over the tables today, increased knowledge about human anatomy as it applies to the stroke (e.g. how the stroke works -- the SPF disclipine of instruction being a good example) today, etc.
I do need to ask you -- as a "reader exercise" -- to name any of today's champions that use a slip stroke. Just one. Any of today's top ten or top twenty or so players that use a known slip stroke. When I say "champion," I'm talking about players that snap-off big tournaments and are in the BCA points list. I'm not talking about past-greats who are still playing and may occassionally win or place in some regional tournament. I'm talking big names. Hint: you won't find any. There's a reason for this -- knowledge about the physics of pool and the human anatomy as it applies to it (e.g. the stroke and mechanics) are much greater these days, and the need for a slip stroke is minimized.
I'm not saying the "Use by:" date of the slip stroke has been exceeded (if I may borrow a great expression from Jerry Forsyth). I'm saying that it's not "required to be one of the greats" like some of the old-timers say.
Personally, one of the best learning stages I went through in my play was learning the slip stroke. I learned a TON about stroking the cue ball, and how to keep the cue straight throughout the cue delivery. I then integrated that knowledge into my
conventional stroke, and "re-built" my mechanics and foundation upon what I feel are superior cue delivery fundamentals -- that of the snooker style, and I gently placed the slip stroke to the wayside in my mind. Everyone says that they used to play better at such-and-such time of his/her life. Well, with me, I think I'm playing just as good -- if not better -- than when I was in the Navy and stationed in Norfolk, VA in the mid-1980s and practically lived in a pool hall (Q-Masters, when it was located on Sewell's Point Road in Norfolk) during my off-duty hours. I just wish I had more time to play these days! (The "woes" of today's working man!

)
I have a kind of stroke slip and I guess I acquired it from reading Wimpy's quote "Light grip is good, lighter is better." Took it to heart played around with it to the point I was throwing the cue, then backed off just a tad and now the cue naturally wants move forward. Sometimes it moves, sometimes not but it wants to. It opened up a whole new realm of possibilities.
3kushn, what you describe here is NOT a slip stroke, but rather a stroke slip. There is a difference -- a slip stroke is "a slip [backwards], followed by a stroke." A stroke slip is "a stroke, followed by a slip [forwards] of the cue." Big difference. What you describe is what Dave Segal (SpiderWebComm) likes to call "throwing the cue" -- in effect, throwing (or letting slide forward) the cue so it travels like a spear through the cue ball. A slip stroke is not that at all. Once one executes the "slip-and-regrip" during the backstroke, positive grip of the cue is maintained (usually) at all times. And in fact, if you watch Wayne Norcross's videos (posted earlier in this thread), you can see Wayne sometimes uses BOTH a slip stroke and a stroke slip -- he "slips-and-regrips" during the backstroke, and then during the forward stroke lets the cue slide through his grip. But keep in mind both are separate and distinct actions.
I apologize for the "War and Peace" response (two posts to do it, no less!), but I hope the info about the slip stroke -- as well as detailed instructions on how to execute it -- are helpful!
Warmest regard,
