Players who have mastered the basics will solve this problem at a glance, but for others it's easy to play a crude move and help White live. The important thing is not to confuse this shape with the one in which White has an extra liberty open (at the marked stone) — that leads to a different result. The problem with the liberty open is a more difficult one, suitably for high-dan players.
