8 + 6 = 14 → 6 ball + 8 spinArrival (left long cushion): 6Ball 2 position (right long cushion): 8Total (ball fraction + spin): 14Ball 2 at the middle diamond of the right long cushion → 8. Ball 2 frozen to the cushion → short cushion 0. Balls level → offset 0. Arrival on the left long cushion between 8 and 4 → 6. Total 8 + 6 = 14 → ball fraction 6 + spin 8.

Total = Ball 2 (long cushion) + Ball 2 (short cushion) + Offset + Arrival (+1 for a firm stroke); Total = Ball fraction + Spin
5 − 1 + 0 = 4 → 2 ball + 2 spinArrival (left long cushion): 0Ball 2 position (right long cushion): 5Ball 2 position (bottom short cushion correction): -1Total (ball fraction + spin): 4Ball 2 between 6 and 4 on the right cushion → 5. Ball 2 level with the 3rd diamond of the bottom short cushion → −1. Offset 0 (balls level). Arrival at the corner → 0. Total 5 − 1 + 0 = 4 → ball fraction 2 + spin 2.
7 − 1 + 4 + 2 = 12 → 3 ball + 9 spin (preferred)Offset (shift): 4Arrival (left long cushion): 2Ball 2 position (right long cushion): 7Ball 2 position (bottom short cushion correction): -1Total (ball fraction + spin): 12Ball 2 between 8 and 6 → 7; short cushion −1; offset gap 2 diamonds, rising to the right → +4; arrival 2. Total 7 − 1 + 4 + 2 = 12 → 3 ball + 9 spin. This is the preferred solution: ball 2 goes to the top short cushion and comes back down along the right cushion.
7 − 1 + 4 + 2 = 12 → 6 ball + 6 spin (not recommended)Offset (shift): 4Arrival (left long cushion): 2Ball 2 position (right long cushion): 7Ball 2 position (bottom short cushion correction): -1Total (ball fraction + spin): 12Same position, same total of 12 → 6 ball + 6 spin. After the right cushion and the top cushion, ball 2 comes toward the carom area, so there is a danger of a kiss; that is why 3+9 is preferred.
7 − 1 − 3 + 2 = 5 → 3 ball + 2 spinOffset (shift): -3Arrival (left long cushion): 2Ball 2 position (right long cushion): 7Ball 2 position (bottom short cushion correction): -1Total (ball fraction + spin): 5Ball 2 → 7; short cushion −1; offset gap about 1.5 diamonds, dropping to the right → −3; arrival 2. Total 7 − 1 − 3 + 2 = 5 → 3 ball + 2 spin. 2+3 is recommended instead.
7 − 1 − 3 + 2 = 5 → 2 ball + 3 spin (recommended)Offset (shift): -3Arrival (left long cushion): 2Ball 2 position (right long cushion): 7Ball 2 position (bottom short cushion correction): -1Total (ball fraction + spin): 5Same total of 5 → 2 ball + 3 spin. This option is preferred to 3+2 because it gives a more natural path.
4 − 0 − 1 + 8 + 1 = 12 → 4 ball + 8 spin (firm stroke)Offset (shift): -14–5 cushions / firm stroke: YesArrival (left long cushion): 8Ball 2 position (right long cushion): 4Total (ball fraction + spin): 12Ball 2 around the 6th diamond from the top on the right cushion → 4; close to the cushion → short cushion 0; offset gap half a diamond, dropping to the right → −1; arrival at the 3rd diamond from the bottom on the left cushion → 8; long (multi-cushion) path, firm stroke → +1. Total 12 → 4 ball + 8 spin.
6 − 0 + 2 + 3 = 11 → 3 ball + 8 spinOffset (shift): 2Arrival (left long cushion): 3Ball 2 position (right long cushion): 6Total (ball fraction + spin): 11Ball 2 around the 5th diamond from the top on the right cushion → 6; short cushion 0; offset gap 1 diamond, rising to the right → +2; arrival between 4 and 2 → 3. Total 11 → 3 ball + 8 spin.
5 − 2 + 3 + 2 = 8 → 3 ball + 5 spin (balls very close)Offset (shift): 3Arrival (left long cushion): 2Ball 2 position (right long cushion): 5Ball 2 position (bottom short cushion correction): -2Total (ball fraction + spin): 8Ball 2 → 5; ball 2 near the middle diamond → short cushion −2; because the balls are very close, the offset is measured with the line joining the inner tangents: gap 1.5 diamonds → +3; arrival 2. Total 8 → 3 ball + 5 spin.
3 − 0 + 6 + 6 = 15 → 6 ball + 9 spin (near the corner)Offset (shift): 6Arrival (left long cushion): 6Ball 2 position (right long cushion): 3Total (ball fraction + spin): 15Ball 2 between 4 and 2 → 3; short cushion 0. Because the balls are near the corner, the offset is measured with an auxiliary line parallel to the line joining the two balls (using the cue): gap 3 diamonds → +6. Arrival between 8 and 4 → 6. Total 15 → 6 ball + 9 spin.
