◇ Just read — no move neededThe chariot that keeps its secret
Instead of the direct 车一平二, Red can rise with 车一进一 — the horizontal chariot (横车). It reveals nothing yet; only after Black commits does it cross the palace (过宫) to a rib file (肋线) — the d- or f-file at the king's shoulder, the two roads into the enemy palace. Against the screen horses the horizontal chariot supports a centre pawn storm and can switch wings in a single slide. Black answers with his own counter-race.
