Very good explanation of major / minor notion. Your answer would deserve to be presented as an article on this site.

Daniel, I programmed your variant on Zillions to see how it looks. I was wondering if the castling done by moving the King 3 steps towards the Rook on both side is intentional? On King's side it means that the King goes on the Rook square. Is that correct?

Yes it's true, they are not huge changes, anyhow it is quite interesting even for us, for example to look at the differences induced by different pawns.

For reason I don't know, I don't see the full diagrams: I only see the boards and the piece in its middle, but the possible moves are not shown.

Can someone help us? We try to play Metamachy with Numerist, I have the black pieces. When I click on one of the 4 which are in the center of the board, it activates (with a framed square) the 4 squares in the center of my lines, but how to move the piece in those squares? I've tried to click, to hold and drop the piece, nothing works. I've tried with Safari and with Firefox. Am I doing something wrong? Thank you

We try to play Metamachy on Game Courier. I have blacks. I can't find how to move a piece to the central squares of my lines and then start the game. Is that preset bugging? Or are we missing something? Please help us to understand. Thanks a lot


Viking Chess Set. Game board and pieces in search of rules. (Cells: 37) [All Comments] [Add Comment or Rating]

Very interesting. I see no mention of it in Pritchard's Encyclopedias. It has nothing to do with Byzantine chess which was played on the spaces, not on the intersections. The closest similar game I know is Circum Morum or Jabberwocky chess invented by V.R.Parton in 1961. But this one was more complex with 5 concentric circles and 61 positions. Maybe your game has been inspired by Parton's one.

I propose to add some ungulates I don't see in the list.

(Source: Le Guide des échecs - Traité complet, Giffard & Biénabe, ed. Robert Laffont-Bouquins, 1993. A big French book with a very large part dedicated to fairy chess and problems).

Okapi: Knight+Zebra

Auroch: Knight + Giraffe

Impala: Knight+Antelope

Zebu: Camel+Giraffe

And my own proposal for a piece that I never found named elsewhere:

Stag: a (2,4) leaper

What do you call an Aanca or an Anka? I can't see what you are talking about

Aurelian, the RNN is called Waran or Varan by problemists. (Source Giffard/Bienabe, 1993)

For the different bent riders, I suggest you take inspiration from different mythical monsters.

Please resist to use Aanca/Anka, I cry when I see that. It is not because the mistake was done once that we are obliged to perpetuate the mistake. Once we know, we are no more ignorant. Aanca is the word used in Alfonso X codex for the F^R. It was the medieval Spanish rendering of the Arabic word Anka. That word designated a mythical giant bird preying elephants like in Persian tales. Murray thought that giant bird was a Gryphon (which was a different monster). OK, Gryphon is too much installed in the CV word to change it, but calling Aanca something else is a mistake.

Especially if it is to designate the N^B which was an Unicorn (meaning a Rhino) in the same Spanish old text!

Look for Hydra, Basilisk, or a full list here: https://en.wikipedia.org/wiki/List_of_legendary_creatures_by_type

Too bad Aurelian you don't want to change your mind. Anka is the word used in Spanish for the Gryphon. Is like if you call a Bishop, a Torre. You can call your piece otherwise, a Simurgh or anything, why a Anka/Anqa/Aanca? Check that page: http://history.chess.free.fr/acedrex.htm


Sergeant. A combination of the Berolina and usual Pawns.[All Comments] [Add Comment or Rating]
Jean-Louis Cazaux wrote on Fri, Dec 11, 2020 08:37 PM UTC in reply to chebetol from Sat Dec 28 2013 08:33 PM:

I agree with Chebetol. Also, "In the diagram below, the Sergeant can move and capture to all the squares marked with a black circle. The Sergeant can make its initial(non-capturing) double-step to the square marked with a green circle." In the diagram, the black circles are green, and the green is red! This page deserves a second look maybe.


Sac Chess. Game with 60 pieces. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]
Jean-Louis Cazaux wrote on Sat, Dec 12, 2020 06:58 PM UTC:

This CV is quite interesting. I like this idea very much. As others, I'm a bit afraid of 2 Amazons per side. I understand the author's reason wishing to keep the standard respective chess lineup.

Then I wonder if it was considered to keep the 2nd row as it is but to modify the back row with Crowned Bishops (Missionaries) on d1,g1; a second Queen on e1 (behind the 1st one); and a single Amazon on f1 (behind the King) ?

Any thought?


Jean-Louis Cazaux wrote on Sun, Dec 13, 2020 06:50 AM UTC in reply to Kevin Pacey from 02:44 AM:

Sure, I was asking to know if what I was thinking had been considered. I have no doubt that this game is popular and I understand that it is not that every dude can alter your game.

I'm probably a bit stuck on the logic, because Sac chess is based on a very logical approach. If B, R and N are considered the basic ingredients, then having 2Q, 2BN, 2RN, 2KB, 2KR, 2KN and a single BRN=A is making it full.

The lineup with BN/Q/A/BN at the center of the back row is keeping the FIDE array in the 2nd row.

I will test a game like this, as a variant strongly inspired by yours.


Boyscout. (Updated!) Moves in a diagonal zigzagline.[All Comments] [Add Comment or Rating]
Jean-Louis Cazaux wrote on Sun, Dec 13, 2020 04:30 PM UTC:

I would like to move this piece is Zillions. I wouldn't say I'm good at programming Zillions.

I use this string: (define zslide ($1 (while empty? add $2 (verify empty?) add $1) (verify not-friend?) add)) I use 8 of them for the piece (nw ne; ne nw; nw sw; sw nw; etc.)

It works but then the value attributed to that piece is too strong because half of the squares it can reach are counted twice (those in position of dabbaba-rider).

Does anyone know how to fix that?

Thank

Jean-Louis Cazaux wrote on Wed, Dec 16, 2020 06:39 PM UTC:

Alas this Man & Beast series for me is frustrating. For reasons I don't know, I see no moves on the diagrams, only a large chessboard and a poor lonely piece in the center. The accompanying text is so long, difficult to get something useful. Too bad because it is a huge work with probably a lot of good points inside. It will deserve a rework.

The name of the German author is Tressau, not Tressan. I know, it's confusing because the original book was written in gothic script and the u and the n are very similar (although slightly different). Here is a u, so Tressau.

It happened the same thing to me. I played Metamachy on game courier, my opponent resigned and now it is registered that I lost and he has won!

Can someone looks what's wrong?

Thanks

Hello Fergus. Yes, the same happened to me for

timurthelenk-numerist-2020-328-848  

Numerist (Black) resigned ... and was declared winner.

Maybe the bug comes from the fact that Black has the 1st action in the game, which is the chose the starting array, placing the central pieces. Then only White plays the 1st "real" stroke.
