Two more potential additions
Titan
A combined 3,0-3,1-3,2-3,3-leaper, the larger analogue to the squirrel. Other names are Cheetah (Silvermann, Cazaux) and Beaver (Gilman).
Plays in Fantasy Grand Chess: Giant Army, 2000, Peter Hatch. Called Titan Plays in Phantastic XIII, 2022, Jean-Louis Cazaux. Called Cheetah
Direwolf
Combined piece of Squirrel and Titan.
Plays in Phantastic XIII, 2022, Jean-Louis Cazaux. Called Direwolf (in the revised edition, formerly Sabertooth)
Giraffe-Ferz, Giraffe-Wazir, Giraffe-Wazir-Ferz
I haven't encountered any of those three pieces in a game.
Here are some rather marginal leapers.
German problemists (see https://dieschwalbe.de/lexikon.htm ) have named a few more leapers:
3,0-leaper: Dromedar "dromedary"
3,3-leaper: Gecko "gecko". Was Betza aware of this name when he choose the letter G in his funny notation for (3,3)?
5,0-leaper is unnamed, Gilman offers Quibbler for this one
5,2-leaper: Korsar "corsair"
5,0-3,0 combined leaper: Kröte "paddock" (since the more natural "toad" is already taken)
7,0-leaper: Hirsch "deer" (one may also consider "stag" here, but Cazaux uses stag for a 4,2-leaper). Gilman's name for this one is "settler".
This was an error. Adrian King's Dayrider is in fact AADDmK.
Alibabarider
Plays in Typhoon and Jupiter, 1999, Adrian King. Called Dayrider in both games.
Queen-of-the-night
Plays in 'Pocket Mutation Chess', by Mike Nelson, 2003.
Add: Called 'Amazonrider' in this game.
I hope my series of comments stops here, but I can't guarantee for that. As a side effect I removed a lot of errors from the English Wikipedia article "List of fairy chess pieces".
I meant the colourswitching piece, the numbers were correct, the last name not. I edited my comment to correct that. Thanks for notifying.

Thanks for the playable diagram.
Just a note to the casual reader: This diagram does not implement the original S(w)eeping Switchers, but a toned down version of them. The Queen-side pieces are more lame than the ones used originally, the King-side pieces are true to the original proposal. In this diagram there are more species of pieces than originally.

Just for the curious: I accidentally found the original proposal of the Sweeping Switchers here:
https://www.chessvariants.com/ratings/-piececlopedia.dir-ideal-and-practical-values-4.html
It got refined with the help of the editors here.

Edit: I see now that it is already nominated as "Knight-Relay Chess", so this becomes a second to that.
Original nomination, gives the name where the variant can be found here:
Here's another nomination for a featured CV:
N-Relay Chess
for popularising the idea of additional moves and captures by Relay.

Is it possible to rename the tag "Piece:Berolina Pawn" to "Piece:Pawn:Berolina"? I have already added some children to Piece:Pawn and it would fit perfectly there, IMO.

There is something wrong with the rating of Fischer Random Chess: In this list it is the favorite of 12, but on its page I count only 11 having it as a favorite.
It has also an extraordinary high score even it it was favorited by 12.


This is a late reply ... the bent riders that are not bent are in fact long known, problemists call them slip pieces (slip-R, slip-B, and slip-Q). The slip-R is also known under the name Panda and plays with this name in the S(w)eeping Switchers army for CwDA (2002).


Another late reply: Yes, before having an account here I signed by comments with "--JKn". Afaik, no one else did.

No. The move zero rule is only to prevent an immediate tactical threat, but not a measure to correct the strength of an army. The additional tempi gained by the move zero rule are worth about one third of a pawn.
Great that you rediscovered the 135-degree-rose. I did not name it back in 2002 but I don't like the name "Worsen" – to me it only sounds like a verb with the meaning "to make worse; to become worse".
I suggest "Rose of Jericho" for this piece. The move pattern reminds me to the ball shape of that plant in dried up state.

HaruN Y rediscovered the 135-degree-rose recently and named it "Worsen"

I don't like this name, I suggest "Rose of Jericho" instead.


Charles Gilman explored those pieces and assigned some more names in the game "Commedia dell'Arte Chess"

I just noticed that piece I name Fischer here was used by Jason D. Wittman, 2000, Mad Chess. It is called Unicorn there.

I just discovered that this game contains the Unicorn, a piece that I later used as Fischer in 10-directional Chess. I have added a credit note in the comment of this game.
I agree with the comments cited in the review: The Stone army (here black) is weaker than the Steel army (here white). I think that the imbalance can be corrected by giving the MAD INFANTRYMAN the possibility to move without capture as a Cylindrical Bishop and making the FOOL also to move and capture as a Cylindrical Bishop. Cylindrical Bishops are equal in value with Rooks according to experienced players of Cylindrical Chess.
P.S. I came back here to find out about the "Stone King" in Derzhanski's list of Chess pieces. I clearly see that the Black King moves as described, but the term "Stone" does not appear here. It is present in the PBM preset and also in one comment on the contest page where also the SteelQueen is mentioned.

It does not matter that the leapers don't promote because pieces are never taken out of the game forever, they all return via drops. The stronger player always has enough pieces to checkmate.
On the pieces: You are free to name the pieces whatever you want, but for the convenience of CV enthusiasts I suggest the addition of the following things:
Ox: It is also known as Alibaba (Alfil-Dabbaba compound piece)
Courtier: It is also known as Zebra, a piece with a long history in Chess.
It also suggest adding Betza notations for all the pieces. It is
Ox (Betza notation AD)
Camel (Betza notation L or C)
Courtier (Betza notation J or Z)
Ram (Betza notation HG)
P.S. I am not aware of other games featuring the Ram. Cazaux's Troll comes close, but it has additionally a pawn move.

The game with ALoR has a completely different dynamic than the original Lines of Relay. A local material advantage on one side creates aggressive tactical potential and the game can be over very quickly.
I designed the original LoR to be balanced: Moving a Queen to the file h would mobilise both Lore Apprentices, not only the own one.

Well, but not very human readable, one has to decode cryptic things like
customPiece3 = r:GH
what is perfectly OK as an instruction for a CV engine, but it is not a note adressing human readers.
