Shapes
Patterns worth recognising, with the liberty arithmetic on each card recomputed from the position so the numbers cannot drift. Read the note at the bottom before you trust the advice.
About this advice
The rules and life-and-death tracks are proved — a solver recomputes every answer, so a mistake there fails the build instead of reaching you. This track is not. The liberty counts on each card are checked; the advice under them was drafted by an AI from general Go material and reviewed by no Go player.
Shape advice is proverbs — true most of the time, with exceptions that matter, and no search settles them. Each card says when its own advice is wrong. Treat them as things to look at, not rules to follow: when one contradicts something you worked out over a real board, the board is the better authority.
