on the cue ball and which is easy to produce as shown in fig1 the cue ball 3 is struck central which is causing no deflection of the cue ball 3 as in fig2 the cue ball 3 is being struck on the central vertical line but with top 5 and bottom spin 7 it has been found that the flexibility of the cue shaft towards the tip end has a great impact on the angle u03be of deflection caused by the cue 1 on the cue ball 3 in fig3 a cue ball 3 is struck with a rigid cue off centre to the right on a horizontal plane from the centre of the ball in the first sequence fig4 the cue tip strikes the cue ball right of centre which starts the deflection process to the opposite side as the cue ball 3 is hit off centre an angled force is exerted on the cue ball this forces the deflection of the cue ball in the opposite direction to the side of impact a rigid cue as demonstrated in fig4 will bend only slightly which forces the cue ball to move aside of the intended direction of the cue ball in fig5 the same shot is played with a cue 11 according to the present invention with a more flexible shaft towards the tip end 2 at impact the cue strikes the cue ball on the same spot as.
