When the Red Cannon is exposed at rank 1, file 6 and the Red Chariot at file 6, rank 5 converge, the board resembles a mysterious painting. The Red Pawn at file 4, rank 8 is under siege, the Black General at file 5, rank 10 has set a trap, while the Black Advisor at file 6, rank 10 waits for an opportunity. This is not an ordinary formation but a dialogue between defense and counterattack.
