Spin = Start + Aim + Arrival (+ Correction)
0 + 0 + 2 = +2Aim: 0Start: 0Arrival: 2Spin: 2Start and aim as in the reference position, arrival at the middle diamond of the bottom cushion (+2). Spin +2: two levels from 12 o'clock in the direction of rotation; ball fraction that sends ball 2 parallel to the short cushion, soft stroke.
−3 + 2 + 2 = +1Aim: 2Start: -3Arrival: 2Spin: 1Start at the 2nd diamond from the top on the left cushion (−3), aim at the middle diamond of the top cushion (+2), arrival at the middle diamond of the bottom cushion (+2). Spin +1; soft stroke at a speed of about 3 cushions.
Ball 2 away from the cushion: −2 + 2 + 3 − 0.5 = +2.5Aim: 2Distance of ball 2 from the 1st cushion (diamonds): 1Start: -2Arrival: 3Spin: 2.5Ball 2 is one diamond in from the top cushion. Start −2, aim +2, arrival at the 1st diamond from the left on the bottom cushion (+3); −0.5 for the distance from the cushion. Spin +2.5.
−1 + 0 + 2 = +1Aim: 0Start: -1Arrival: 2Spin: 1Start at the 4th diamond from the top on the left cushion, i.e. the middle diamond (−1), aim 0, arrival at the middle diamond (+2). Spin +1.
Arrival on the long cushion: 0 + 0 − 1 = −1Aim: 0Start: 0Arrival: -1Spin: -1With reverse spin the cue ball goes from the top short cushion to the bottom short cushion and from there to the right long cushion (a double cushion the long way). Arrival at the middle diamond on the right cushion (−1). Spin −1: one level from 12 o'clock in the opposite direction.
