Six balls, one white and nobody else at the table: clearance #356 is about finishing the job in as few visits to the white as you can manage, fouls counted as extra shots.
No ball lies within 35 cm of a pocket. Expect long pots from the start and give yourself room for error by playing the safest one first. The side pockets are the natural target for ball 1 and 3.
No two balls are touching, so every ball can be played on its own.
Playing with no aiming error, our Expert computer cleared this layout in 6 shots, potting in the order 5 → 3 → 4 → 6 → 1 → 2. It committed 1 foul on the way, each counted as an extra shot. 1 of its shots potted nothing: they were position or safety shots to set up an easier pot.
A tidy target is to match the Expert: one shot per ball plus a spare. Keep the white near the middle of the table and the next pot will always be close.
