Rose Chess XII. With Nightriders, (Half-)Roses, Spotted Gryphons and War Machines. (12x12, Cells: 144) [All Comments] [Add Comment or Rating]

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.

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.


Jörg Knappen wrote on Sat, Nov 23, 2024 12:11 PM UTC:

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.


Leaperhouse. A 10x10 drop variant consisting of only Leapers, Shogi pawns and Kings. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]
Jörg Knappen wrote on Sun, Dec 1, 2024 02:40 PM UTC in reply to A. M. DeWitt from Thu Nov 28 05:45 PM:

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.


Jörg Knappen wrote on Sun, Dec 1, 2024 03:00 PM UTC:

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.


Lines of Relay (LoR). Chess variant featuring a new type of morphing piece, the Lore apprentice, on a standard board together with the standard pieces. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
💡📝Jörg Knappen wrote on Mon, Dec 2, 2024 09:46 AM UTC in reply to HaruN Y from Sun Dec 1 10:47 PM:

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.

Jörg Knappen wrote on Sat, Dec 7, 2024 02:55 PM UTC:

I do not like the renaming of the piece to "Lancer" because that name is already taken: Problemists have named the (2,4)-leaper lancer. The name is also dangerously close to the piece named Lance in standard Shogi.

Is it really the combination of Maorider + Moarider that you describe here

Moorider: afz(afzafz)K

Or does your description allow the rider for each step choosing again between Mao and Mao steps? A simple combination piece must choose one step pattern (Mao or Moa) for all of its steps.

Recharged Chess. Upgrades on ranks two and eight. (9x9, Cells: 81) [All Comments] [Add Comment or Rating]
Jörg Knappen wrote on Sat, Dec 21, 2024 05:54 PM UTC in reply to Bn Em from Fri Dec 20 11:05 PM:

I think I get it as such: The pawns starting from rank 1 (9) get recharged on rank 2 (8). On field e1 is the King, so no rule for row e is needed. Skipping rank 2 seems possible, but why should a player make such kind of move? This recharging is a king of gate-in where the pieces to be gated in are already present as pawns on the initial board.


Gravitational Chess. Major units fall back toward the friendly side.[All Comments] [Add Comment or Rating]
Jörg Knappen wrote on Tue, Dec 31, 2024 05:03 PM UTC:Excellent ★★★★★

Playing around with the interactive board I start appreciating this great invention. It looks like Chess in the first sight, but it is so different!

Knights are colourbound, Bishops are colourswitching, but both pieces keep control over their original target squares, provided there is a fall-back square behind. All pieces are more powerful in the endgame compared to the normal Chess men. One rook can mate unassisted and forced, one bishop and a king mate against a lone king.

Some open questions, to one who has access to the original sources for that game:

Is castling really allowed while rooks cannot move along their base lines? It fells like cheating even more than in standard Chess.

Can rooks and queens pass a move (going one step orthogonally forward and fall back)?

Can rooks and queens capture by igui a piece in front of them ending on their starting square (can only be a pawn)?

Not knowing the original description by the author of that variant it is only a guess.

It is plain spam, in this case placed in the person information. It doesn't matter if it is placed by hand or automatically.

Usually this kind of spam consists in creating a personal profile only, and because no none notices that personal profile it is considered usually harmless. But in this instance the spammer tries to stir up attention by posting well-formed nonsense in the comments.

The moderators of this site should act appropriately.
