Korea’s own chess, close cousin to Xiangqi but with real differences worth learning on their own terms: the King and Guards can cut diagonally across the palace from a corner to the centre, the Elephant leaps a stretched 1-then-2 pattern, the Horse moves freely with no blocking leg, and a Cannon can neither screen off of nor capture another Cannon.
Guards and King share the same moves and both can cut across the palace diagonals from a corner to the centre — use that shortcut to react quickly on either side of the palace. Cannons are powerful but brittle: they can't jump another Cannon or capture one, so a well-placed Cannon of your own can wall the AI's off completely.
