Kevin Pacey wrote on 2022-05-17 UTC

On the topic of piece names, I've noticed that in some languages the name for a chess rook translates to ship (or to boat, also). Thus 'Admiral' (or my choice of 'Sailor', in Sac Chess) gets bonus points as a choice of name, perhaps (for the piece type in question, a promoted rook in shogi), i.e. a person who uses a watercraft's power.

Maybe there's a slightly related argument that a real-life knight, in the past, is a person who uses a horse (arguably knight is a more elevated title than horseman, which would also work).

I can receive emails from the site just fine. The problem is there's no way to get it verified.

Although I couldn't receive the required email, I cheated by looking at the undelivered email sent to chessvariants.com. Using the code provided in that email, I was able to verify my email address after I fixed some bugs in the change_password.php script. Basically, I had misnamed some columns by reversing the order of the two words composing their names. So, if you can get the email, you should now be able to verify your address.

When I tried to test the script for verifying email with my Yahoo address, I never got the email. Looking at email sent to chessvariants.com, I see an email about being unable to deliver this email. It will keep trying until it is five days old, which will be on the 18th. There is a similar email for you, as well as a subsequent one about your email being returned. It is looking like Yahoo Mail has stepped up its spam blocking, which is also blocking even more legitimate mail. Since this server runs on a VPS with a fairly unresponsive hosting company, I'm not sure what to do about improving our mail delivery. That is why I no longer require email verification for creating an account.

In my opinion, respect for the original doesn't matter when making a derivative of something (in this case, a chess variant). What matters most is to have fun designing it, and ideally, for others to have fun playing it as well.

Chess is not sacred, we do not need to protect it.

Complementarity - Part I. With Short Range Project in mind, list of a highly specific set of pieces defined by simplest compounds.[All Comments] [Add Comment or Rating]
Samuel Trenholme wrote on 2022-05-15 UTCExcellent ★★★★★

A while ago, I looked at 31 possible short range pieces. I have now expanded this research.

I have written a small C program which looks at all 16,777,215 possible leapers that move at most two squares. Some findings:

  • I expected around half of all possible pieces to be colorbound in some way. Wrong. 16,452,080 (over 98%) pieces are not colorbound.
  • There are 104 non-colorbound pieces with three moves, 2,512 pieces with four moves, and some 2,696,337 pieces with 12 moves.
  • Only 2,944 possible pieces are Bishop colorbound: These relatively few pieces can go to the same 32 squares a Bishop can go to.

With some 16,452,080 non-colorbound pieces, if we replace the knight, bishop, and queen with a random non-colorbound short leaper, that gives us 4,453,099,898,116,838,912,000 which is, what, 4 hextillion possible variants, and that’s keeping the king, pawns, and rook.

OK, if that’s not enough possible variants, we can also add the ability for a given random piece to be able to be a rider in any direction it can leap (e.g. a fers-rider is our bishop; a wazir-rider is a rook, and a knight-rider is, well, a knightrider), where we randomly choose, from all the moves a given leaper has, for it to be able to ride in a random number of directions. For example, if we look at the wazir, then randomly choose which directions it moves like a rook and which directions it can only move one square, we get 16 possible pieces. If we do this for all 16,452,080 non-colorbound short range pieces, we get some 282,232,643,280 possible pieces, just over 2 to the power of 38 (2^38 or 2 ** 38 in Python notation).

This means an 8x8 board with random non-colorbound pieces and using a standard chess set has some 6,344,961,231,517,063,209,074,884,200,517,463,972,290,560,000 possible variants (the pawns and kings can keep their moves), just over 2 to the power of 152.

Hello @Fergus Duniho,

I can receive emails from the site just fine. The problem is there's no way to get it verified.

It didn't ask me to verify during the registration.

After registering, I found no menu where the verification was possible. The only way I found was clicking omn my own name in a game, getting here: https://www.chessvariants.com/who/csarmi

Now here I did have an option called "Verify Email" which takes me to this php: https://www.chessvariants.com/login/change_email.php?submit=Verify

It says this: Mail was sent from change_email@chessvariants.com to Máté Csarmasz

That does actually send me an email from change_email@chessvariants.com that contain a link like this (I've anonimized the keyword and code in there: http://www.chessvariants.com/login/change_email.php?userid=csarmi&newemail=(myEmail@gmail.com)&keyword=(keyword)&code=(code)

Clicking that takes me to a page where I get this message:

"Please click the Confirm button to change your email address from myEmail@gmail.com to myEmail@gmail.com". There's a button called "New Email" where my email address is entered.

Looks like a change email form to me.

Nevertheless, I did click that button. After I've done so, the site still says my email address is unverified and I still don't get notification emails to my games.

So what should I do?

Theresa Dubé wrote on 2022-05-13 UTC

What about Falcon-like pieces involving a Rumbaba or other HD component? Especially now that George Duke’s patent on these pieces has expired, so you’re free to make “Falkeschach”. (I also want to see more Rhino-like pieces that mix all 3 of Rookwise, Bishopwise, and Unicornwise steps (of course having a 3MD instead of an EMD); the first one of which has a Fortnightwise 3MD on a cubic board, and therefore could be called “Fortrhino”.)

My suggestion for the Chevron version of the Falcon would be Warlobird. (Which also allows a suffix for pieces mixing oblique moves like how the Falcon family mixes radial moves: for example, a Gnubird would mix Knight and Camel moves.)

Thanks, Sam. This is not too bad... I gather my algorithm was correct, but I assumed that the positions would be numbered 1-960 (as people count), not 0-959 (as programmers count). In fact, it looks like I just add one at the end after placing the pieces. Not sure where I got that - it's unlikely I just made it up, but it does seem that the consensus is to number the positions starting at 0. Anyway, easy fix.

Bn Em wrote on 2022-05-12 UTC

Which of the two possible stepping Fortnights do you mean?

  • The one taking one each of wazir, ferz, and viceroy steps? Given that Gilman starts from the various bent/crooked pieces which only have two kinds of step, this is probably a bit out of scope (corkscrew pieces with one kind of step aside).
  • The one taking three Ferz steps, two in one direction and one at 60° (dual to the hex Shearwater)? That'd match the two‐of‐one‐and‐one‐of‐the‐other pattern of the Falcon, and arguably as a Shearwater extrapolation could be nameworthy (I'd've suggested Fulmar, a family of birds related to shearwaters beginning with the F of fortnight as shearwater begins with the S of sennight, but it's already taken (albeit with unclear etymology) for Zephyr+Lama; perhaps Petrel, the group including the fulmars and still beginning with a labial consonant, would suit it?), but presumably he either didn't consider two diagonal directions different enough without the AltOrth‐ness, or it just didn't occur to him. And there are also Nonstandard Diagonals at small enough angles (35°) for more Falcon‐like pieces there too

For a stepping‐Trison component I'd probably choose the former, but individually both are interesting enough imo. There's still a few bird‐of‐prey names unused I think so if one were keen to name them in Gilmanesque fashion all that'd remain would be finding a game to use them in…


Theresa Dubé wrote on 2022-05-12 UTC
A 3d version of the Falcon that would make sense, would also incorporate root-3 diagonal “Unicorn” moves. A combination of Duke’s Falcon with Gilman’s Vulture, Kite, and a piece Gilman surprisingly didn’t name (I think it would be a “Multipath Stepping Fortnight”, if my Gilmanese is correct). Gilman calls the leaping version of this piece a “Trison”.

@HG, I had managed to do it despite some small setbacks. You know what's funny? This game also has berolina pawns!


H. G. Muller wrote on 2022-05-12 UTC

To add a new piece (say X / x)  to the GAME-code generated by the Play-Test applet you would have to add its move definitions at the end of the legdefs array, and supply functions X and x that return where in the legdefs array you have done that. Determining the latter is a bit of a pain; there are comments in the legdefs table that in parentheses indicate where the definition for each piece type starts, and you can then count the numbers appearing after that. Note that because the 'bare Pawn' is an asymmetric piece you would need different definitions for the white and the black one.

The move definition of a (white) FIDE Pawn is:

1  1  0  1     1
1  1  1  1     2
1  1 -1  1     2
1  1  0  2   16577 // pawn(1)
1  1  1  1     4
1  1 -1  1     4
0

The first 3 lines would suffice for the Shatranj Pawn; each line starts with the number of legs (always 1 here, as Pawns only have simple moves), the forward and sideway step size, the 'range' (= number of times the step can be repeated) and finally a code to indicate what the move can do (2 = capture, 1 = non-capture, e.p. capture = 4) and other details (like whether it is a virgin-only move). So the 4th line is the double-push, the 5th and 6th are the e.p. captures. For your bare Pawn you would leave these lines out. The final 0 indicates that the definition ends there, and that the moves that follow (if any) are for another piece. The move specifications for a piece should always end with such a 0.

In the example I copied this from the white Pawn was the first piece, so it starts at element 1 of legdefs. The special moves of that Pawn start at element 16 (as the three normal moves each take 5 numbers to describe). That means that just behind legdefs there is a line

def P cond #0 1 16;

that tells the code that the move definitions of piece P start at 1 (normal moves) and 16 (special moves = moves having side effect, such as creation of e.p. rights, or disappearance of pieces elsewhere). For pieces without special moves the latter number should always be 0. So for the bare Pawn you would have to add a line there like

def X cond #0 ... 0;

where the ... is the location in legdefs where the move definition starts.

I don’t know the correct procedure to file a bug report for ChessV, so I will just note the bug here.

Description of bug

ChessV does not use the standard Chess960 numbering scheme for opening setups. See https://chess960.net/wp-content/uploads/2018/02/chess960-starting-positions.pdf for the reference of correct number to starting position. In particular, ChessV is off by one (Position 0 in the official spec is position 1 in ChessV, etc.)

Steps to reproduce

Open up ChessV. Choose Fischer Random Chess. When it asks for an expected setup, choose setup #692.

Expected results

The opening setup should be RBBQKNNR (Mongredien chess)

Actual results

The setup is BRQKNNRB

Notes

Position 693 is the Mongredien setup in ChessV, so one just needs to add 1 to the official position number to get the corresponding position in ChessV.

Position 518 (519 in ChessV) is the standard chess starting position.

This is my attempt to put a chess variant on a non-standard tiling. While the hex tiling has been fairly extensively explored for chess variants, and there are a few games using a triangle tiling, and Tony Paletta has explored the rhombille tiling, and George Dekle has explored a few tilings, this is the first chess variant I know of that uses a demi-regular tiling (Onyx, a Hex-style connection game, uses a similar archimedean tiling).

Any comments or civil criticism is welcomed.

Until this variant gets published, guests can see a Zillions implementation of the game is at Zillions of Games; that zip file includes a PDF with full game rules.

Very Heavy Chess. A lot of firepower with all compounds of classical chess pieces.[All Comments] [Add Comment or Rating]
Jean-Louis Cazaux wrote on 2022-05-07 UTC

@Bn Em: thank you for your comments. Quite informative. About Heroin, drug or female hero, I was sure that it was a link. According to WP:

The head of Bayer's research department reputedly coined the drug's new name of "heroin," based on the German heroisch which means "heroic, strong" (from the ancient Greek word "heros, ήρως").

To be back on this debate on BWN and RFN, I hesitate between Popess/Heroin which are a bit generic or Pythia/Valkyrie which are more strongly culturally marked.

At this moment, although I like the second pair, I prefer to stick with the first couple because it will be easier to use in an other CV where a Greek or a Viking reference could be awkward. I think that Popess and Heroin do carry what I wanted them to carry, the idea of being at the top of a pyramid, being feminine, one link to spiritual, one link to physical strength. They are immediately understandable.

Sure, they are not very common words, but BWN and RFN are not very common in CVs either.


Jean-Louis Cazaux wrote on 2022-05-07 UTC

No I disagree. Popess is a word that can be used to designate someone, feminine, with a dominant position in a given domain. For instance I heard just today on radio someone speaking of a lady working in the shade for foreign affairs in France, saying she was the popess of the diplomats in her time in Paris circles. Even "pope" is used sometimes with this type of speech.

Maybe you don't know. You didn't know what a pythia is, so you don't know everything.

So, I have no problem at all to use Pope or Popess, not less than using King, Queen, Emperor, Guru, Emir, Shah or I don't know what.

On the contrary when you use the name of one person, many may think that you represent this person. Imagine I would want to honour Macron in chess, and I say, this piece is a Macron. Then if we have 2 Macrons on board, it is strange. There is no difference, if it is about Macron or Sissa.

Now, I don't care at all if games are using 2 Sissa, or 3 or 10. It's really fine with me. I understand the reference, I like it.


Fergus Duniho wrote on 2022-05-07 UTC

but as Jean‐Louis notes, if we can have two Sissas…

Sissa is a name borrowed from a person's name, in this case a mythical inventor of Chess. Presumably, the piece is not understood to be this very mythical inventor of Chess but is just named in his honor. This is different than a title for a rank that is allowed to only one person at a time within a given hierarchy.

If we're talking prior usage, it's worth mentioning that Valkyrie has at least three distinct usages already: A queen that can also relocate friendly pieces, Bishop capturing as Queen, and a 3D‐specific piece moving as Rook or jumping two steps on either kind of diagonal. Conversely Heroine (albeit perhaps due to potential Drug associations) is afaict only used by Gilman for a Hex‐prism‐specific compound

Fwiw, Gilman also uses Hero on that last page, and there's also a Hero in Hero Chess. Surprisingly, Gilman seems to lack names for the two pieces under discussion (Knight+Chatelaine/Primate, to use his terminology) though. I suppose one could suggest Catholicos for BWN, as a rank above cardinal that starts with Ca‐ (for the usual extrapolations: Zetholicos ⁊c), but besides the long and awkward Archchancellor (note the double ⟨ch⟩) idk what he'd've used for the RFN

Pythia seems to be unused (understandably, given its relative obscurity); arguably it falls afoul of Fergus' objection to multiple ‘popesses’, as there was only one Pythia at a time, but as Jean‐Louis notes, if we can have two Sissas…

Imo Popess feels a bit awkward as a word, and I share Jean‐Louis' reservations re unnecessary loanwords; Pythia, Valkyrie, Heroine, and Baroness all sound fine to me

There was a typo in a new bit of code that was preventing you from selecting CSS as your rendering method. For some reason, this preset works only with CSS, and it will not work if you try to display the board as a GIF, PNG, or JPG image. I repaired your log so that it uses CSS again, and you can now continue your game.

I now see that you were using the unprogrammed preset that actually uses a custom grid rather than the vhex shape. So, I was going in the wrong direction when I tried to make it use the vhex shape. So, the problem is different than I thought it was, and I will have to start over. In the meantime, I have reverted it back to the custom grid shape.

Who is Who on Eight by Eight. A compilation of Zillions-estimated piece values on an 8x8 board.[All Comments] [Add Comment or Rating]
H. G. Muller wrote on 2022-05-06 UTC

Consensus values for pieces in Xiangqi are R=10, C=6-4 (opening-endgame), H=4-6, A=E=2, P=1-3 (unpassed/passed). So C and H only approximately half a Rook, and it depends on the game phase which of the two is somewhat stronger. And one should realize here that the Horse (Mao) is only worth half an orthodox Knight on a board as crowded as orthodox chess. (Which is quite a bit more crowded than Xiangqi, so that extrapolating the Xiangqi values to that higher density might give H=3 and C=7. That would then imply N=6, which indeed gives the correct relative value of R and N. So this suggests C could be worth slightly more than a Knight in a FIDE context.)

In games without drops the opening value of pieces is dominated by what they will be worth in the end-game. E.g. it is still much better to have a Rook in the opening than a Bishop or Knight, even though a Rook on a crowded board trapped behind his own Pawns is hardly of any use at all. But it is almost unavoidable that it will get to express its true power later in the game, so that hanging on to it is a good strategy. But for Cannons the end-game value is low, and rather than waiting for their potential to develop with time, one should try to trade them in the most-favorable way before that time.

To do a meaningful empirical test of the Cannon value you would need to do it with an engine that handles it well. Otherwise the value will be underestimated. ("A piece is as strong as the hand that wields it.") And handling hoppers well means you have to be very much aware when it becomes time to exchange them for other minors. If you do that too early you would not have exploited any superiority while it still existed; if you do it too late you will be stuck with them when they get nearly useless. To make the program seek trading at the right moment it is essential that it makes the hopper value dependent on the piece density, in the correct way. Which would have too be determined empirically too.

I just found that Ivan Derzhanski was calling this piece a Dragon in his study made in 2001.

Yes Zillions overestimates hoppers and ranks the Cannon slightly below the Rook, and the Vao slightly below the Bishop, and the Leo slightly below the Queen, which is really excessive for the 3 of them.

This is probably related to some changes I made to the formfields_customization.php script for something unrelated to hexagonal chess. I got it to use the vhex shape again, but when I do, the pieces are misaligned with the CSS board, and the board appears misshapen when it is automatically drawn as an image. So, something else is going wrong. Since it's late, I'll look into this further tomorrow.

Hi Jean-Louis.

For what it's worth, 'heroine' is often used over here in movie reviews, to describe a character that's the leading lady (and/or helper of some sort to the male 'hero'). I mentioned Joe's 'Hero' piece type since he chose the name for it in spite of any misgivings that it might possibly be a bit generic.

Sometimes it's easy to be over- (or under-) critical of one's own ideas, especially on second thought. I think 'heroine' is just fine for RNF type.

The preset under Official Glinski Coordinates, Medium Size Pieces is not rendering properly. You can see the problem in this game

Thank you for all your feedbacks.

To Greg, python and heroine carry the same meaning in French and other languages as well. In French is even worse for Heroin, as héroine is the word for both the female hero and the drug.

To Joe, even if I'm French, I'm reluctant to use French words. It is not a solution, it is not good if two different pieces are named with the same word but in two different languages. Although there are (famous) existing cases (Ferz, Alfil, Cavalier, Chevalier, ...)

HG's Pythia is very good. Not all religions are Christian in the span of mankind history and geography. The Pythia was an important person in Greek religion in the Antiquity. https://en.wikipedia.org/wiki/Pythia

Yes, Heroine is kind of generic and yes, not very common in usage. I'm not very happy with it.

All that demonstrates that we have progresses to make for the gender issue :=)

If I may intrude into the discussion of how pieces are named and refer again to my variant 'Chess 66'. We have discussed Chess 66 and clarified inconsistencies. For my part, I have taken up the suggestions in my description by adding explanations and clarifying examples. The functionality of the switches as I imagine it is not compatible with Fergus 'Reroute 66' (occupied switsches can be skipped, switching between fields of switches is possible). This should be discussed. Therefore I would have the request to publish my variant 'Chess 66'. Are there any reasons against it?

While I'm pretty inactive these days, I do play the occasional game, and when I check for moves, I check what's new. First, thank you Kevin for pointing out names I've already used for pieces.

For your tentative 'high priestess', I think "grande prêtresse" is possibly a good choice.

Similarly, for 'hero' I think "héros" with both the accent and ending "s" is a decent choice.

The accents in the names mark them as non-English, and the spellings maintain the separation of your and my pieces without really changing the names you wished. I admit that I am naming deficient and no one except me may actually like the alternates, so feel free to ignore or delete this post.

For what it's worth, 'Hero' is already a known Fairy Piece on this website (Joe Joyce might have invented).

In general, hierarchical Christian religions of the sort that have bishops do not have very high ranking positions for women. So, if you want a piece that is a high-ranked female religious figure that fits with bishop, you're not going to find one. Alternatives include using a neologism like Cardinaless or abandoning one of your requirements for naming the piece. Mixing religious titles from very different religions doesn't work well, because Christianity, from which we get bishops, doesn't easily mix with other religions. Diagonal moving pieces do not always have religious names. For example, the Queen moves diagonally but doesn't have a religious name.
