The Red Cannon on File 6 Rank 6 creates a defensive 'rainbow bridge' by staying stationary, while the Black Horse on File 5 Rank 10 threatens. The Black Advisors on File 5 Rank 9 and File 6 Rank 8 support, but the Red Pawn on File 3 Rank 8 still needs protection. The Red General on File 4 Rank 1 must consider moving to avoid being 'sunk'.
