Wow, I didn't see that coming. I knew my horse was pinned, but for some reason, that obvious move didn't occur to me.
I would love to play Korean chess, but I don't want to be interrupted by my return home right at the peak of the game. This game took us about two weeks, and I leave in less time than that....
It looks like it solves a few minor flaws of Chinese chess (the limitation of the elephant, the uselessness of the pawns, and the immobility of the king), but the cannon not being able to move except by jumping seems limiting While it may work well in Ito Shogi where there's always a piece to jump over, it will weaken the piece a lot in this game. Maybe that won't turn out to be a bad thing. Have you tried playing it already? How have you found it?
