Jeffrey Ignacio, a favorite player of mine to watch, uses a slip stroke. I didn't notice it until I played him a few years ago in California. Now I see it in his videos as well. Jeffrey is as natural a talent at pool as there can be... what a stroke.

do yourself a favor and witch this video. it shows his stroke, as well as some of the most ridiculous cut shots you will ever see
I wanna see that guy in your avatar with the fence post use a slipstroke!
For those asking about benefits I think there are several. One is you automatically stroke through the cue ball, always a good thing. Two, you hit the cue ball with the same range of motion as your practice strokes. It is like you clicked a button and your cue was several inches longer at the tip end.
Ultimately, you probably can't do anything with a slipstroke you can't do with another stroke although it is deadly when shooting with a cue ball frozen to a rail. However, aside from anything else, the slipstroke is an art, a real thing of beauty. That is why I try to practice it every chance I get. A piece of lost video, I watched somebody with a huge slipstroke that seemed like either his forearm was made of rubber or he had a few extra joints in that arm. Mesmerizing is the only word!
