I-Chess. Large board variant that adds two more piece types: the wolf and the eagle.[All Comments] [Add Comment or Rating]

I had defined the king as royal and as HG had said that has solved the eagle problem. Now I'm thinking about the pawns problem. I had also asked the author for a different name.

The pawns are taken to be regular pawns as I used the stock button to generate them. I don't know how to define the xBetza move for them as they can move from anywhere on the home half of the board towards the middle of the board and one field after crossing the middle of the board! But I'm sure it is pretty long!

A (non-capturing) move up to half-way the board is fmW* in the Diagram. You could make that an ifmW* if it is only from the initial position. A Pawn with such a move would also have been in stock, as 'omega pawn'. On such very deep boards the e.p. capture would not completely work, though, as the Diagram handles at most two e.p. squares. (The AI should do it correctly, though.)

Thanks, HG

Greg, The inventor of the game has patented I-Chess so he wants to stick with the name. What is there to be done?


Greg Strong wrote on Thu, Oct 8, 2020 04:04 PM UTC in reply to Aurelian Florea from 03:49 PM:

Patented with whom? Is there any way I can confirm this?


📝Aurelian Florea wrote on Thu, Oct 8, 2020 04:10 PM UTC:

I can show a picture maybe.


📝Aurelian Florea wrote on Thu, Oct 8, 2020 04:16 PM UTC in reply to Greg Strong from 04:04 PM:

Greg, but the game you have showed is IChess and this one is I-Chess. Is not that different?


Greg Strong wrote on Thu, Oct 8, 2020 04:37 PM UTC in reply to Aurelian Florea from 04:16 PM:

I would have preferred a more unique name (IChess and I-Chess would be pronounced the same) but if it is true that "I-Chess" is patented under that name I guess we'll have to go with it.


📝Aurelian Florea wrote on Thu, Oct 8, 2020 04:38 PM UTC in reply to Greg Strong from 04:37 PM:

Sounds fair to me!


H. G. Muller wrote on Thu, Oct 8, 2020 05:32 PM UTC:

But that is a pretty big IF, I would say... And it might actually make it illegal to publish the game here at all.

Agreed.  I must admit I am skeptical...

And it might actually make it illegal to publish the game here at all.

I think this could make it illegal to play the game here, but descriptions of patented inventions are generally public.  And, just because a patent office has issued a patent, it does not mean that the patent would stand up in court. Personally, I very much doubt a patent of any chess variant would stand up to legal scrutiny.


H. G. Muller wrote on Thu, Oct 8, 2020 06:45 PM UTC in reply to Greg Strong from 05:36 PM:

But the Interactive Diagram does allow one to play it here, against the AI...


Greg Strong wrote on Thu, Oct 8, 2020 07:11 PM UTC in reply to H. G. Muller from 06:45 PM:

Good point


📝Aurelian Florea wrote on Fri, Oct 9, 2020 07:28 AM UTC:

These are the documents that contain the patenting data. Unfortuneatly one is in Romanian. I personally am not sure about their applicance. 


H. G. Muller wrote on Fri, Oct 9, 2020 08:02 AM UTC:

It doesn't matter much in which language they are, as the lettering is too small to read anyway.

What intrigues me, though, is that the left document has the map of Netherlands / Belgium / Luxemburg as a logo (in the colors of the Belgian flag).


📝Aurelian Florea wrote on Fri, Oct 9, 2020 02:34 PM UTC:

So then, what is there to be done?


Greg Strong wrote on Fri, Oct 9, 2020 03:28 PM UTC:

Sorry, I don't really know. The inventor went through the trouble to protect his intellectual property and I don't know why he did that or what uses he considers to be ok or not ok. Since he patented it, he must consider some uses to be "not ok" or why bother?


📝Aurelian Florea wrote on Fri, Oct 9, 2020 04:27 PM UTC in reply to Greg Strong from 03:28 PM:

I'm sure about him wanting the game to be published here as he is the one trusting me with this endeavor.


Greg Strong wrote on Fri, Oct 9, 2020 06:48 PM UTC in reply to Aurelian Florea from 04:27 PM:

Can you please confirm with him that he is ok with people potentially playing it online here? (interactive diagram/game courier). If so, then it is ok with me.


📝Aurelian Florea wrote on Sat, Oct 10, 2020 10:47 AM UTC:

Mister Zama has agreed about the game being played on the site!


Greg Strong wrote on Sat, Oct 10, 2020 04:37 PM UTC in reply to Aurelian Florea from 10:47 AM:

Ok, page updated and posted!

This looks like it could be a good game. My simple estimate of the value of the pieces: P=1, N=2.5, B=5, R=7, E=6.5, W=7, Q=12. I like the fact that the Rook, Eagle, and Wolf should all be very close in value.

NOTE: The Wolf has been used previously in my game, Hubbub, under the name Gryphon. The Eagle may be new.

The positions of one of Black's bishops and eagles in the SETUP diagram currently appears to be incorrect.


Greg Strong wrote on Sun, Oct 11, 2020 03:50 AM UTC in reply to Kevin Pacey from 03:46 AM:

Fixed. Thanks!
