I have an answer to your 2nd question:

The R3 is named Kongo (Guardian of Gods) in Taikyoku Shogi.

There's also a B3, named Rikishi (Wrestler) in Taikyoku Shogi.

Note that the Taikyoku Shogi pieces move differently then pieces with the
same name in other larger Shogi variants.

I have seen speculations (sorry, I don't have sources ready) about a precursor of the pawn: A forward moving piece using custodian capture (as in Tablut). It may be related to the game Petteia played in ancinet greece (the rules of that game are unfortunately lost). This explains the divergent nature of move and capture of the Shatranj pawn.

Here's a first pack of additions, all from the following new source:


George Jelliss: Theory of Moves, Knight's Tour Notes 2001,
http://www.ktn.freeuk.com/9a.htm

Notes are mine and introduced by the tag Note:

          Note: synonyms are waffle (CwdA) and phoenix (large Shogi variants)

diamond - compound leaper (1,1)+(0,2)
          Note: synonyms for this piece are duke and kylin

emperor - compound leaper (0,1)+(1,2)
          Note: a synonym is marquis (Derzhanski's list drawing from Adrian  King)

ferfil - compound leaper (1,1)+(2,2)
         Note: most established synonym on the CVP is 'modern elephant'

frog - compound leaper (1,1)+(0,3). The simplest amphibian.

prince - compound leaper (1,1)+(1,2)

pterodactyl - compound leaper (3,3)+(5,5)+(0,15). The simplest triple range amphibian

templar - compound leaper (0,2)+(1,2)

wazaba - compound leaper (0,1)+(0,2)
         Note: synonym woody rook (CwdA)

Here are a few additions sourced from:

Hans Gruber: Märchenschachlexikon, Schwalbe - Deutsche Vereinigung für Problemschach, zuletzt aktualisiert am 26.08.2011,
http://www.dieschwalbe.de/lexikon.htm

The source contains tons of information on fairy problem conditions and some pieces. Most of them are outside the scope of the Concise Guide to Chess Variants, but I propose the following additions:

Piece names

ibis - elemental piece, (1,5)-leaper

lancer - elemental piece, (2,4)-leaper
    Note: This piece has a different german name, Hase (engl. hare)

okapi - compound leaper (1,2)+(2,3)


Note. If the charset is mangled, then: ä ist ae (a-umlaut) and ü ist ue (u-umlaut)

Sigh, link rot hits again. Fortunately, I have printed the Theory of Moves when it was available on the net.

Christine, you found another nice reference, and I immediately love the names toad and newt for the other simple amphibians!

Jörg Knappen wrote on Fri, Jan 6, 2012 07:52 AM UTC:
This is a suggestion to David:

Add all contest winning games to the Game section.

This gives a nice overview of the activity of the CVP community over a decade.

Hi Charles,

I skimmed through my sources again and could not locate a reference to 'gazelle' as a synonym for the okapi (Knight-Zebra-compound). Where did you get it from?

I share your feelings with respect to the name 'prince': it is quite unspecific and used for a whole bunch of pieces, most notably the commoner. The aim of my comment was to give a summary of this important source.  Note that Jelliss gives prince for Knight+Ferz (not Knight+Wazir) following the male/female logic from the King/Queen pair. And problemists call the Janus/Palladin piece princess.

The name hospital(l)er is  worth mentioning for the knight-alfil compound, kangaroo as a synonym ist certainly worth mentioning, too. Outback Chess was a contest winning variant, at least.

Going through my sources I found a synonym for the newt: it is called counsellor in Quang Trung Chess and this name propagated in Töws' piece creation system and in Ivan Derzhanski's list.

The lore apprentice (Zauberlehrling) of Lines of Relay is an offshot of the querquisite, I conceived it by misunderstanding its moves. See

I am aware of the name Okapi for about a decade when I found it in several problem databases on fairy chess problems. However, a search here

http://www.softdecc.com/pdb/search.pdb

(enter PIECE='Okapi' in the query form)

reveals some problems going back to 1970, Most Okapi problems are authored by Erich Bartels, but other prblemists joined the crew. If you have ever seen an okapi (I did, the Franfurt/Main zoo is a proud owner of the rare species), it is a particulary well choosen name for a horse-zebra vompound.

Digging through references on Gazelle, I found it only as a synonym for Camel (the (1,3).-leaper) in Turkish great chess V

http://www.chessvariants.com/large.dir/greatchessv.html

This is confirmed by George Duke here:

http://www.chessvariants.com/large.dir/falconpatent.html

and George know more chess variant literature than I can ever dream of.

The Ferz-Knight compound has the synonym priest - again a very unspecific name. It occurs in Töws' Generic chess piece creation system and Derzhanski's list.

I once aggressively tracked names for compound leapers and noted them on paper, it looks like a good idea to put them on the CVP pages some time.

This is kind of a fun question: What would be a good male version of a Banshee?

Ganymede Chess. A 12x12 variant inspired by Ralph Betza's Chess on a really big board, Centennial Chess and Adrian King's Typhoon (among others). (12x12, Cells: 144) [All Comments] [Add Comment or Rating]
Jörg Knappen wrote on Tue, Jan 10, 2012 07:08 AM UTC:
MArk Hedden's frog (WFH in Betza notation) is taken from Adrian Kings games (Sciroco, Jupiter, and Typhoon). To distinguish it from Jelliss' frog (FH in Betza notation) one could call it frog king (derived from crowned frog, crowned being a standard prefix for forming names for pieces moving as a commoner + something).

I love the name Dullahan very much. It has inspired a new experimental army for CwdA, named the Fearful Fairies, to be pulished here soon.

Drunken Nights. A toned down version of the Nutty Knights for Chess with different Armies. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
💡📝Jörg Knappen wrote on Wed, Jan 18, 2012 08:06 AM UTC:
Yes, backwards as a King means 3 directions, and no, forward as a Knight are all 4 forward directions, not only the two 'fast forward' directions.

💡📝Jörg Knappen wrote on Wed, Jan 18, 2012 08:09 AM UTC:
To the other question: Only the Drunken Night and the Charging Paladin mentioned in the notes section are new pieces, the others are the original pieces from Ralph Betza's Nutty Knights. The Nutty Knights page also has movement diagrams.

💡📝Jörg Knappen wrote on Wed, Jan 18, 2012 08:25 AM UTC:
To the very first comment: The crippling of the Charging Knight is intentional. The fact that a Charging Knight and a King can checkmate a solitary King has dramatic influence to the endgame. Replacing the Charging Knight by a Charging Moo leaves the endgame value untouched, and I doubt that the weakening in the opening phase and the middlegame is sufficient to tone done the Nutty Knights enough. But I have not playtested your proposal.

As I said in the notes, there are lots of possibilities to weaken the Nutty Knights, if you find another one, it is fine.

💡📝Jörg Knappen wrote on Wed, Jan 18, 2012 12:57 PM UTC:
Yes, it does.

💡📝Jörg Knappen wrote on Wed, Jan 18, 2012 06:27 PM UTC:
Sigh, you are right, and I cannot correct the mistake because of umlaut problems I cannot edit the page any longer. I defintely did not want to change the Colonel in this army.

💡📝Jörg Knappen wrote on Thu, Jan 19, 2012 08:30 AM UTC:
Finally I found a work-around that allows me to update the information here, editing in the missing user name to submission form. The forward Ferz move is now added to the Colonel, as it should be.

The piece I inadvertedly created, the Charging Chancellor, may also be of the right strength to tone the Nutty Nights down. An army with srunken Nights and Charging Chancellor together will probably already being on the weak side, but inside the error margin of my estimates.

Grandmasters of the Nutty Nights may prefer this very weak version.

Official Football Chess. Variant from the 1960's with pieces replaced by football players. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

This is a double excellent for this game.

The first excellent goes to Hans for digging this game out and posting it here.

The second goes to the game design: The inventor has really thought hard of the initial position, and it makes a fine game. There is a lot of tactical tension in the setup, but there are no obvious exploits. Great game!

I received the rule book and I like the many ideas in chess 2. It is an interesting game to remember where did I see rampant elephants before? Nemesis? 

Nice food for thought!

Jörg Knappen wrote on Sat, Jan 21, 2012 08:16 AM UTC:
Hi, Charles, I think you are supposed to follow the link and undergo the 'purchase' procedure, as there is currently a special offer at $0.00 for this nice chess variant.

There is far too much in it to summarise it here in a comment. There are 6 different armies (one of them the FIDEs), and each of the new armies is equipped with 'mutators' (as George terms it) that still feel fresh and unusual. 

Besides the new armies, the general rules are extended by new ways of winning the game, bringing down the number of draws, and duelling (introducing a poker-style element). So Chess 2 is different even with FIDE vs. FIDE armies.

Carpenter. compound of Knight and Dabbaba.[All Comments] [Add Comment or Rating]
Jörg Knappen wrote on Sat, Jan 21, 2012 08:48 AM UTC:
As far as I can see, the name 'vicount' (without an s) is indeed Peter Aronson's invention. The piece itself is absent from Derzhanski's list ( http://www.chessvariants.org/piececlopedia.dir/whos-who-on-8x8.html ) and from Töws' Generic chess piiece creation system ( http://www.chessvariants.org/unequal.dir/genericchesssystem.html ). I recommend a look into the latter for some other names for rarely used pieces like Boxer (Commoner + Beaver) or Foursquare (FNLJG in Betza notation, L is Camel, J is Antelope, and G is Tripper).

Derzhanski's list also gives sources to games, Töws obviously draws from similar sources, but does not give them.
