I can't figure it why but I have a green background and a blue highlight. Look here, please:

Thank you Fergus. I am attempting to implement the changes you requested. The hardest one will be to rework the piece design/set. If I upload a missile piece image to go with a current set, would I be able to have the piece image that is associated with the letter M be the Missile (instead of the Marshall/Chancellor)? For Game Courier purposes, I really wanted all of the letters to correspond to the names of the pieces.

Fergus, What about the ability of changing the blue color of the highlighting when showing possible moves.

It uses the border color to highlight possible moves.

@Fergus, Hello,

I had asked 3 questions on this thread 2 weeks ago. It seems that you have missed them. Can you find time to take a look?

I added links to the two games you mention. So that the reader doesn't have to consult another page to know the full rules of your game, it would help to include the rules from Capablanca Random Chess for randomizing the setup.

I also should mention that I don't really like the images I currently have assigned to the archbishop and chancellor with the Diagram Designer, but I could not figure out how to submit my own piece design there.

I see you're using a Cannon image for the Chancellor and a Marshall (or Chancellor) image for the Missle. You may submit images for a set to an editor. The new images should be designed to fit in with the style of the set. I would recommend uploading your new images and letting an editor know in the comments. Many other sets portray the Chancellor and Archbishop as a combination of two pieces, which makes them instantly recognizable.

I see you were styling your text. In particular, you put BIG tags around your text, and you used CSS to put a border around each piece description. In particular, I am getting a scrollbar at the bottom of the page, which I think is caused by your CSS. I will refer you to Preferred HTML form of contributions.

HG,

For fairy max the promotion zone of the games is still 1 or 3 deep (no 2)?

Later Edit: Is there a way to do castling if the king and rook start on the second to last rank (like in expanded chess say)?

Even Later Edit: How do I tell Winboard that the promotion zone is the last 3 ranks?

Does anyone know if there is a digital implementation of this game, (not on a truly infinite board for obvious reasons), perhaps on Zillions of Games, or playable in a browser?

At the time I wrote that there was a problem with engine-defined variants running in a match that started from an externally set-up position, where the position sent by the engine overruled the position requested by the user. But I think this was fixed in the latest beta version of WinBoard. There it should be possible to run a tournament or match specifying a 'position file' in the Tournament Options dialog, which contains the FEN(s) of the desired start position(s). I hope.

H. G. Muller wrote on 2021-06-14 UTC

I made some modificaions to the AI of the Interactive diagram. In particular, I simplified the Quiescence Search. This because it was prone to search explosion in variants with super-powerful pieces (such as hook movers and multi-capturers). The new QS only always searches capture of the last-moved piece when it is worth less than the attacker, or when it is unprotected. Other captures are only searched if there is enough remaining depth; new captures (i.e. those not possible 2 ply earlier) require a depth of 1/2 ply, other captures a full ply. This puts a limit to how long an exchange can continue.

This new QS is weaker then it was (but faster, and in complex situations far faster). To partly compensate that the default search depth is now 2.5 ply instead of 2 ply, and the depth can be adjusted in steps of 0.5 ply (from 2 to 4 ply).

I also slightly improved the positional bonuses for centralization; the bonus for that is now flatter in the horizontal directions, and pieces with a forward orthogonal slide but no distant other forward moves (such as Rooks and Lances) are exempt from the bonus. This avoids the annoying Rb1 after Nc3, then followed by Rc1 after Bd2, and prevents amassing all pieces on the central two files.

Daniel Zacharias wrote on 2021-06-14 UTCExcellent ★★★★★

I wish this game were more popular. It seems like an excellent design. The piece selection seems strange at first but after thinking about it I can see the beauty of it.

I imagine the aanca could have originated as an enhanced ferz, to go with the bigger board. Then the knights could have become unicorns by gaining a diagonal slide after their leap to complement the aanca. The crocodile is a fairly obvious addition. The giraffe and Lion both make knight-like leaps, suitable for the large board, and the Lion includes and extra 3,0 leap which removes it's color binding and forms a nice looking pattern.

The result of all that is eight pieces with a nice range of power and an aesthetically consistent set of moves. There are all of the 2,1 3,1 and 3,2 leaping moves, the rook and bishop moves, and bent rook and bishop moves (unicorn and aanca). The leaping pieces are differentiated in power by some of them having additional movements, but they don't ever feel like arbitrary combinations.

The initial setup is also elegant. The Pawns start as far apart as they do on the 8x8 board, and the pieces are all on the back rank. The promotion rule fits well with this setup and is another great innovation.

I think the main weak points, if there are any, would be the pawns and the king's leap. It seems unlikely that the king would benefit much from a 2 square leap on such a big board with so much empty space; and perhaps modern pawns would be better. But overall this variant appears to be carefully designed.

I changed some H2 tags to H3 tags, and I moved one section from Rules to Notes. The script for displaying member-submitted content normally adds the appropriate H1 and H2 tags, and tags entered by the author should begin with H3.

Thanks for your feedback.

I have reinvented this chess variant into Kingsmen. The pawns are on the third rank like in Shogi, and cannot double advance on the first move (and hence no en passant).

Also like Shogi, all non-royal pieces in Kingsmen promote on the last three ranks. A promoted piece can move like a King (one square in any direction) in addition to its original moves.


2.Manticore and 2. Griffin ?[Subject Thread] [Add Response]
Aurelian Florea wrote on 2021-06-12 UTC

I was thinking at bent riders that take 2 steps and then bend and keep going to that direction. This would be called very plastically Rook2 then bishop and Bishop2 then Rook. Would 2.Manticore and 2.Griffon be good names for them?

You have explained to me here :

how to set up a machine match to test something. Is this still the way to do it or are there different things now?

I tidied up this page, replacing non-Unicode characters, and replacing the low effort ASCII diagram with one generated by Game Courier. It's still an ASCII diagram, because I wasn't sure what images to use for some of the pieces.


Improving Typography[Subject Thread] [Add Response]
Fergus Duniho wrote on 2021-06-10 UTC

I have adjusted the em values for the headings so that specific integer pixel values will be used when the body font is 16px. These are 36px for H1, 32 for H2, 29 for H3, 26 for H4, 21 for H5, and 18 for H6. Instead of making the differences the same between each pair of neighboring headings, I used smaller differences where the style changed more, and I put a distance of .5em (8px) between distant headings using the same style.


Fergus Duniho wrote on 2021-06-10 UTC

Instead of setting the body text at 18px, I have erased code for setting the size of the body text, so that it will now use the system default. On the Windows desktop, at least, this is typically 16px. I checked multiple devices, and on each one, it seemed to make the text smaller, though Android and iOS devices did not let me inspect the elements and determine the precise size.

One reason for making this change is that Literata, which is now the body font instead of Lora, has a clearer look at smaller sizes. Another is that it should make the display more responsive to particular devices. Instead of using a fixed size across all devices, it lets the device determine the size. Also, I had previously set the font-size for comments to 16px, and I haven't had trouble reading comments. However, comments will now display text at the same size as the main content instead of at a smaller size. So, comments should generally display at the same size as they used to. Finally, the font size will now better match whatever zoom level someone prefers to use his browser at.

Since the heading sizes are defined with the em unit, which is determined by the body font size, they adjust according to the body font size. So, with the body font a bit smaller on most devices, the headings will also be a bit smaller.


H. G. Muller wrote on 2021-06-10 UTC

But can you also do that with headers?


Fergus Duniho wrote on 2021-06-10 UTC

Someone might want to add paragraphs in a smaller-than-standard font.

If you want small text, you can enclose your text in <small>small tags</small>.

I had computer trouble, so I had no opportunity to check it out yet.

Fairy-Max does ignore game names that start with a capital. I forgot what was the reason for that (but originally there was one). But when you change the T to t the variant will appear in WinBoard's New Variant menu, from where you can select it. (If you did not put the definition too far down in the fmax.ini file; WinBoard can only display a limited number of engine-defined variants.

You did not specify what piece should be used for K/k in the pieceToChar string. Change it to

PNBRQ.EA.........G......MKpnbrq.ea.........g......mk
