◇ Just read — no move neededA wandering king dies
The general who wanders dies on open lines: a chariot finds his rank, a cannon loads his file, a horse forks his corner. Here the black chariot has already taken rank two and the wandering king on e2 is in check with the whole road home still to walk. Every step out of shelter must pay rent — in the opening this is the habit called 不露帅: shift the advisors and elephants only when the plan needs it, never to idle. The safest palace shape never changes: general deep, advisors flanking, elephants home.
