Start 0 (3rd diamond from the bottom on the left cushion), aim 0 (1st diamond from the right on the top cushion), arrival 0 (bottom-right corner). Spin 0: at 12 o'clock.

The most widely used system in Korea for 단장단 (short–long–short) 비껴치기. 비껴치기 is the grazing shot played by hitting ball 2, near the cushion, thinly and sending the cue ball to that cushion. The system resembles the Sunrise–Sunset system, but the 1st cushion is the short cushion: ball 2 lies near the short cushion, and the cue ball takes it thinly and goes to the short cushion (1st cushion), the opposite long cushion (2nd cushion) and the other short cushion (3rd cushion). The system calculates not the aim point but the spin to be used: the sum of the start, 1st-cushion and 3rd-cushion values is the spin level.

When? When ball 2 is near the top short cushion and the cue ball has to take ball 2 thinly and go to the top short cushion, the right long cushion and the bottom short cushion (3rd cushion); the cue ball is usually in the lower half of the left long cushion. The same numbers are also used in 세워치기 (steep-angle, long-way grazing) positions.

Watch outThe spin values are levels around the clock, not a number of tips of side spin: +4 is exactly 3 o'clock; +1 to +3 lie between 12 and 3 o'clock, above the equator.

Watch outIn the diagrams the line after the 1st cushion is the ideal-reflection path to the chosen arrival; the real path changes with spin and speed.
