◇ Just read — no move neededNo road, no power
A chariot stuck behind its own horses and cannons is furniture — the strongest piece on the board reduced to guarding one palace corner. In the opening, judge every move by one question: does it open the chariot's road or block it? (车路畅通) This is why development has its fixed choreography: the cannon slides away, the horses step aside, and only then do the chariots roll down the cleared files. Note in the model line how every single move opens a road for a bigger piece behind it.
