The >Great Chess 10x10 was invented in Germany by Erwin Ortlauf and first published in the German chess magazine `ROCHADE Europa` 08/1997 as "Das Grosse Schach 10x10".It has some new pieces and looks complicated but also interesting.
All who are interested can read the rules and download a small application to test the game here !
I think my brain would explode trying to keep a track of what pieces were being attacked and how ... gothic and janus chess are hard enough for me ... but you are right, it does look interesting.
:) Whisperz,that`s why this variation is not very prevalent until yet. But I can say after some time you can become familiar also with these new pieces..
Btw I have the real pieceset of this game and you can see some pics on my page Caissus Chess
WhisperzQ,I have bought this chessset at Erwin Ortlauf (the inventor),it was the last one.:).At this time he has looked for a company,which wants produce the chesset and the board in series. But I don`t know if he has found one.
