System formula
băng 3 = bi cái − băng 1. Ví dụ 50 − 30 = 20. Đánh với ép-phê thuận, lực vừa; bi cái ≈ cao 1 típ.
The classic diamond system for long–short–long rail paths. Cue ball numbers 50 at the corner, 60–90 up the short rail, 40→10 along the long rail; first rail numbered 10–70; third rail = cue − first.
