Three ways to escape
Three doors lead out of atari, and you check them in order. EXTEND toward open space: each extension adds liberties, but only run where the road stays wide — a forced extension toward the edge or into a waiting ladder (6.3) only delays the capture. CAPTURE: if a neighbouring enemy group is itself in atari, taking it removes the threat at the source. CONNECT: join a friendly group with liberties to spare. When all three doors are shut, abandon the stone — pouring moves into a lost stone while the opponent takes big points elsewhere is the classic beginner's sin. Here exactly one door stands open. Black to play: run into open space.
