When i first figured this out, I was experimenting with a closed bridged techniques. One time I really locked my cue in my bridge and it could only move in a straight line. I took a shot which i initially thought was correct but my subconscious tried to make an adjustment as my tip was approaching the Cb and at the same time i started rising off the shot and naturally i missed.
Impossible. There is no such thing as a bridge so tight that the cue can only go straight...or anything close to it. BIG misconception.
Crooked strokes HAVE to be corrected by various other means having little to do with the tightness of the bridge as CHAMPION players prove in every match they've ever been in...using an open hand bridge with great frequency. Some actually prefer it.
