Six balls, one white and nobody else at the table: clearance #350 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 2 and 6.
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 9 shots, potting in the order 3 → 4 → 2 → 5 → 1 → 6. It committed 1 foul on the way, each counted as an extra shot. 3 of its shots potted nothing: they were position or safety shots to set up an easier pot.
Treat the awkward balls first. Moving a rail ball or splitting a pair while you still have easy balls left is cheaper than facing it last with nothing to fall back on.
