This position is not just a simple exercise in chariot and cannon play, but a battle demanding the sharpness of a craftsman's fingers. Red moves first, but before them lies a massive black blockade wall, shielding all of Red's paths. Without careful analysis of each detail, Red will fall into fatal mistakes like 'the 7-ton exposed chariot' without controlling the outcome. This is the formation where students must deeply engrave into their minds the subtle traps of Black's defense when they wish to launch a decisive attack.
