I hope to get rid of this kludge, one day. Perhaps this is already achieved, but the price is that you then have to define a captureMatrix. A ^ in that matrix outlaws hopping in a type-specific way, so that you could keep specifying the universal hop ipfmR, and then outlaw doing it over all enemy piece types, but not with friendly piece types, by writing as many ^ as there are piece types (shorthand ^N) in the row for the Helepolis, after a dot . (which would apply to hopping over an empty square, which is nonsense and so doesn't have to be outlawed).

Just a thought: What if this could be done with i^pfmR? Would that confuse things too much?

73. Yaf. In the Berber languages of northern Africa, including the still-extant Tuareg, the alphabet used is called the Tifinagh. One of the letters is yaf (), and the piece bearing that name (and appearance) also has a move that mimics it.

The Yaf first moves one space sideways; then may move one or two spaces forward or backward; and from that endpoint, may continue in its original sideways direction, sliding like a Rook. ([sW?sW?fW?sR])

How useful this piece is could easily be the subject of some debate. I could see it as a decent piece to have on either end of a row in a large-board game for use as mid- to late-game defense, or possibly to help corner an opposing King for checkmate.

It's not the only letter of the Tifinagh that could represent a good chess move, though. Yaa (), yagn (), and yagh () could be interesting too, to name just the ones that don't look like Roman or Greek letters and/or already-existing chess moves.

Oops. Thanks for the typo catch!

74. Bharal. I've done a little work with fifth-perimeter leapers, and while most of the practical pieces in that group are compounds with shorter leapers, if there's one fifth-perimeter atom that I'd actually put into a game of my creation*, this (2,5) leaper is the one. (AX)

A bharal, also known as a blue sheep, is native to the upper Himalayas, and is distinctive for the males' large, outwardly-curved horns (the females' horns are shorter and straighter). It's also the second-longest leaper (after the Klipspringer of southern Africa) in the bovine family.

Part of what I like about the Bharal is the general look (though I do need to rework this one; I'm currently in the process of thickening all bovid ears, and the head proper may need remodeling). It's also surprisingly agile for a long leaper; it can make a "Knight's tour" covering the entire board (of any size), can easily leap across a 3x3 spell zone, and on a larger board has a decent selection of spaces that it can land on in 2-3 moves.

And of course there's my favorite part: the puns. Compound it with a War Machine, and you have a Bharal Roll. Compound it with a Joker, and it's a Bharal of Laughs. Let it make two leaps per turn, and it's a Double Bharal. Compound it with an Archer, and it's a Shooting Fission a Bharal. (Okay, maybe that last one's scraping the bottom of the bharal.) And I'm sure there are plenty more.

(I'm also working up a [pun-free] QBRM set for this piece, focusing on Tibet.)

*Dealer's Chess doesn't count.


Ultima. Game where each type of piece has a different capturing ability. Also called Baroque. (8x8, Cells: 64) (Recognized!)[All Comments] [Add Comment or Rating]
Bob Greenwade wrote on Fri, Sep 29, 2023 06:35 PM UTC in reply to Fergus Duniho from 06:02 PM:

My eye:

1. King. Suitable mainly for display.

2. Chameleon. Suitable mainly for display.

3. Don't recognize, but I'd play with this one.

4. Knight, though it could be used as a longer-range alternate Knight such as a Nightrider or Midnighter. Good for either play or display.

5. Don't recognize, but good for play. (I might use that as a Berolina.)

6 Archbishop, perhaps? (It looks like it could be a decent Inquisitor or Kuhani, actually.) Another one suitable for either play or display.


Bob Greenwade wrote on Fri, Sep 29, 2023 09:38 PM UTC in reply to Fergus Duniho from 07:07 PM:

These pieces are not in this game. See the description of the game on this page for the available options.

Oh, I'd reached this from just viewing Comments, and thought it was from another page. I hadn't even noticed that it was Ultima! (Now, where's that "embarrassed smile" emoji?)

(I still like the horse one for a Midnighter, though.)

I redid the Bharal while I was also doing a bunch of others, and here's the result:

I do like it much better.

The visual pun is quite funny ngl; I wouldn't have said either it or its replacement is terribly suggestive though

Still, the "visual pun" version would go well with the Gerfod. ;)

Eventually I will need some additional buttons anyway, to indicate other things than a piece or a hole. E.g. check and win squares for the morph board, evaporate / explode for the capture matrix. 'Blank' could be another button in that group.

AFAICT this getting done, plus a clear way to assign a morph board and/or capture matrix to a piece, would complete the improvements.


Bob Greenwade wrote on Sat, Sep 30, 2023 03:47 PM UTC in reply to H. G. Muller from 08:04 AM:

What is not clear about the assignment? The page already mentions in three places that you have to do this by clicking on the move of the piece in the table (In the permanent help text below the table, the help text that appears when you open the morph & confine section, and the introductory text).

D'oh! Once again, I miss the painfully obvious.

A row of buttons for the win and explode options could be located above the table for setting the capture matrix.

And don't forget the "blank" button (for removing entries placed by mistake). :)

Perhaps there should be a button 'Duplicate'...

That seems a little awkward, but much better than anything I could come up with. (My best idea was allowing a space-slash-space in the move section, separating the two different moves.)

75. Ancress. and 76. Metropolitan. These are a couple of pre-existing pieces, both from Charles Gilman's Conclave Ecumenical Chess. I think they're worth looking at, especially for large variants (12x12 and larger).

The Ancress is a combination of the Rhinoceros (sometimes also called the Anchorite) and the Rook. As a Rhinoceros, it can move one space orthogonally, and then proceed from that point diagonally like a Bishop.

The Metropolitan is a combination of the Gryphon and Bishop. As a Gryphon, it can move one space diagonally, and then proceed from that point orthogonally like a Rook.

Each has both orthogonal and diagonal slides, yielding Queen-like properties without actually duplicating the Queen; while arguably more powerful than the Queen, each has something it cannot do that the Queen can (direct diagonal or orthogonal moves, respectively).

Aside from any concern about the Metropolitan's shape making it difficult to grip, I'm actually quite pleased with how these two came out. Both would be fairly distinctive on a chessboard.

Monochrome monitors are pretty rare these days. In fact, I don't think I've ever set my eye on one since the 1990s. So, I think your color scheme would work fine. If you're really worried about it, you could tweak the shades of the colors so monochrome displays show them in distinctive shades of grey.

Other than that, the only thing I'd say is that pieces on the board should have their moves on the table shaded green, just like the Absentees. If you think they should be differentiated, then perhaps cyan would do.

And did you make any changes to the piece selection list? A couple dozen of them seem to have vanished, including several that I was relying on for Short Sliders.


Bob Greenwade wrote on Sat, Sep 30, 2023 11:18 PM UTC in reply to H. G. Muller from 08:32 PM:

Can you tell me which piece(s) you are missing, so that I can see if I have this problem too, and if so, what causes it?

Oddly, it's now the problem that seems to have vanished. I had been missing at least the plane, templar, wolf, and zebrabishop, to name just the ones that I wanted to use.

I finally got a start on this this evening, and so far it's had more wrinkles than my Jedi Elvis costume when it's straight out of the suitcase. I'll have so many questions for H.G. (and probably Fergus) when I go back to it Monday....

Bob Greenwade wrote on Sun, Oct 1, 2023 02:35 PM UTC in reply to Jean-Louis Cazaux from 06:52 AM:

Fair enough point; I should've explained the names a bit further (even though they're Gilman's).

An ancress (a word unfamiliar even to most native English-speakers) is a woman who has cut herself off from secular society entirely for religious reasons, staying in small quarters in an abbey, convent, or other religious building. The word is the feminine form of "anchorite," for a man who does the same (it's also Gilman's name for a Manticore/Rhinoceros).

I'm presuming Mr. Gilman was using Metropolitan to describe a woman who does the opposite: living among the people in a city, being around them as much as possible. (Probably a better word for it, in that context, would've been Socialite, but Metropolitan is what's stuck.) What I was going for there is a sort of Eiffel Tower/Empire State Building mashup, though now that you mention it I probably shouldn't have set aside my usual base. This is one of a handful of pieces where a good, logical design escaped me.

I like the Simurgh as an alternate name for the Anchorite; but isn't Qilin basically a different rendering of the well-established Kirin?

I do thank you for your feedback on those; a suggestion for a better look for the Metropolitan would be very welcome (especially from you, Jean-Louis).

As for those other three, I just managed to get together workable Reaper and Harvester pieces. For Cerberus I've tripled what the Musketeer's Dog can do, from F2sW to BsW3; Hydra is a cool-sounding piece, but evokes images of something extending the Snake, possibly as the Gryphon/Rehinoceros. Similarly, the name of Godzilla evokes something like a Fire Dragon that takes up four squares. (But that's just me; half the established pieces in this game, including most of the orthodox ones, don't quite scan for me, with the Bishop and Knight being two of the worst offenders.)


Bob Greenwade wrote on Sun, Oct 1, 2023 04:41 PM UTC in reply to Bn Em from 03:43 PM:

Per M&B13, Metropolitan is apparently “a rank in many episcopal churches”, presumably the same as described here on Wikipedia; the connection is thus with the Bishop component in the same way that he uses feminine forms to indicate Rook components.

If you can somehow muster a Pallium that'd probably be about as on point as you can get; failing that, perhaps sth cathedral‐like? (Idr whether you've done a cathedral yet; my usual browser setup is reluctant to show the pictures and in any case seventy‐odd pieces is a lot to remember!)

I think a pallium would be both doable and logical. I'd probably want to add a staff or some sort of headgear to make it visually distinctive from behind, but that should work! I'll get to work on that tomorrow.

And I do tend to be reluctant to use physical structures for pieces; the only other exception I've made, discounting the Rook, War Machine, and pieces based directly on them (such the Fortress and Helepolis), have been the Guard and the Pyramid, which also don't have my usual base.

yes Qilin and Kirin are the Chinese and Japanese version of the same mythical animal. Probably inspired by the African giraffe in old ages. I'll see if I can find a better name. For Hydra and Cerberus, I wanted a three-head beast because the pieces they represent are triple barrels. The Godzilla was not a name given by me, the source is older although I don't remember who/where at the moment.

For a new name for your Qilin, you could try Azure Dragon, Yinglong, Kihawahine, Ryu (my choice), or Rainbow Serpent.

I tend to think of the Hydra as having nine heads, but if each head is a direction there could be eight, each representing a "triple barrel." (You go ahead and keep the Cerberus and Hydra the way you like it. I'm just giving my perspective, not asking you to change anything.)

The only place I can find the Godzilla piece referenced is Who is Who on Eight by Eight; even the Wikipedia page directs there, and I don't quite understand the reference made on the page. (Is there a Fantasy Chess on ZoG?)

Our comments crossed each other. I take Indrik for Rhino+Rook.

Excellent choice!


Bob Greenwade wrote on Sun, Oct 1, 2023 06:28 PM UTC:

OK, my turn to seek out a little brainstorming.

What sort of modification would be on a piece labeled as "silent"? I'm wanting to make a couple of pun-based pieces (Silent Knight and Vao of Silence; there could be other possibilities), but I'm not sure how I'd apply it to a piece's move, nor how I'd represent it visually.

It can be either a restriction or an enhancement, as long as it applies equally well to leapers and sliders (and something that can be induced, in the manner of the Relay Knight).


Bob Greenwade wrote on Sun, Oct 1, 2023 06:57 PM UTC in reply to Jean-Louis Cazaux from 06:45 PM:

Nice thoughts! If that, or something like it, could be coded into the ID, I'd definitely use it for the two pieces mentioned. (The Vao of Silence imposes silence on other pieces; that would be the really hard part!)

If you're interested in having other games featured, please make sure they are playable both online, preferably through Game Courier, and against a computer opponent, ideally Zillions-of-Games or stronger.

This is good information to have. I definitely want to make GC and ZoG for Short Sliders (the one game that I've submitted so far that I think is most worthy), though I also intend to work on Desert Dust, Hundred Acre Chess, and Zwangkrieg, as well as others that I haven't posted yet.

I'd think that such a thing would be as difficult to work in as the restriction on my Chicken Pawn's backward move that it only works if the piece is under attack. At least, I think it'd take a bit of reprogramming for either to be done (that is, either having the "silent" restriction or imposing it on others, as well as the Chicken Pawn's restriction).


Bob Greenwade wrote on Mon, Oct 2, 2023 11:45 AM UTC in reply to Jean-Louis Cazaux from 08:30 AM:

Thank you HG. It was only some guesses from my side to answer Bob's open brainstorming about a "silent" pieces. At this stage, no need to develop any code.

Agreed. I might use that idea for "silent" and "silencing" pieces in the future; I'm also still open to other suggestions, ideas, and trains of thought. No need for any new code for that any time soon.

(I may use the Chicken Pawn soon for a "food fight" game, but I'm not definite about that; a better idea may arise.)


Bob Greenwade wrote on Mon, Oct 2, 2023 12:08 PM UTC:

77. Anti-Pawn. It's been a while since I featured a pawn for the Piece of the Day; whether this fits the category is a matter of opinion.

This could also be called the Un-Pawn, Counter-Pawn, or Backward Pawn. It moves like a standard Pawn, but backward only: one orthogonal move backward, or capturing one diagonal move backward.

The player never starts with an Anti-Pawn; rather, a forward-moving pawn (or spear, or other forward-moving piece) reaches a promotion zone, and promotes to it, so it can "advance" from the far end of the board back toward the player. Once the Anti-Pawn reaches the first row (or, if you prefer, the Pawn Row), it then promotes again, this time to something much more powerful (such as a Japanese Lion, Tengu, Sphinx, Sabertoothrider, or such). After all, it just traversed the board twice without getting captured; some type of extra-special reward should be in place.

As for the appearance, I just figured that if a standard Pawn had a sphere on top, the Anti-Pawn should have a cube. There's no getting them mixed up that way!
