The first-line ladder again, mirrored: this time your pressing stone stands on the right, so the edge is closed behind White and the whole chase must run left toward the far corner. Direction is the first thing to read in any ladder — here there is exactly one road, which is why the chase works with no help at all. Atari from the second line and the script takes over: crawl, atari, crawl, corner. Black to play: atari the white stone to start the ladder.
