When the two Red Horses interlock at file 5, rank 5, the position becomes dangerous. The Red Cannon at file 2, rank 1 must be cautious as the Black Pawn at file 3, rank 2 is preparing to 'Advance' to file 4, putting pressure on the Red Chariot at file 3, rank 1. The Black General at file 5, rank 10 needs to defend tightly against the Red Chariot's 'Crossing' move.
