I have been playing pool for quite a while and i have never ever seen anyone do what i saw this lady do...a while ago my APA nine ball team qualified for the TRICUP... well we were doing really well. One of our team mates was playing a woman who was ranked a 3 or 4 here is what she did... the 4 ball was the ball in play it was about a ball width from the bottom rail. The woman had ball in hand but had no place to play the 4 so a safety was her only option. the best shot was to bump the 4 to the bottom rail leaving the cue against the four... a real soft stroke is needed to do this not many 3's have developed this type of stroke..I guess this lady knew she didnt have a soft enough stroke to play the shot so this is what she did She put her cuestick on the table slid it so that the tip of the cuestick was a close to the cue ball as she could without touching it. she then walked up toward the shaft put both hands on the shaft and lifted the shaft upward...when she lifted the shaft up ward the tip made contact with the cueball sending it softly into the 4 ball thus parking the 4 ball against the bottom rail with the cue ball snug against it..My mouth droped for two reasons one i had never seen that done and the fact that a 3 could come up with an idea like that..we just looked at each other and everyone one the team turns to me i guess since i have more pool knowledge than most and all i could say was.."I have no clue if that is legal or not"
