Hey, IvanKosintsev!
Can you please make a diagram of what you mean? I want to be sure that I understand your meaning; because I know you always have great ideas. (Your variant, Waterloo, is still enjoyed by multiple chess.com members today!! I still have a game pending with Vickalan. lol)
In the meantime, Dax and I are going to get our first testrun started; on the board that I created.
Good game! But it's better to play without the river on the standard 13x13 go board and without the empty line in a kingdom. For a democratic Asia this is more practical and hence more popular.
