The yellow boxes become unreadable in dark mode (remember the rule: specify both background and foreground, or specify neither).

Are the new pawns allowed a 2-step first move?

Metamachy. Large game with a variety of regular fairy pieces.[All Comments] [Add Comment or Rating]
J Andrew Lipscomb wrote on Sat, Nov 16, 2019 02:49 AM UTC:

The term "royal" in this context specifically means the "capture/mate me to win" property. The term "prince" has been used both for pieces with the King-move but no such property (Tempête sur l'Échiquier comes to mind) and for pieces that serve as a backup royal (Chu Shogi, Tamerlane). Prince is a reasonable term for either, but the clarification is also reasonable.

Possible variant on that: use Q' etc. to indicate the pieces of black's starting army, and the plain letters for white's. That way, each symbol still means the same thing no matter which side it's on.

Or use English symbols QRBN for one color and German symbols DTLS for the other...


Caïssa Britannia. British themed variant with Lions, Unicorns, Dragons, Anglican Bishops, and a royal Queen. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]
J Andrew Lipscomb wrote on Wed, Jul 23, 2014 09:11 PM UTC:
"Also, do Dragons block Queens as Alibabariders usually move, or can they block Queens on the squares they leap over (As a semi-leaping Queen)?"

As I read it, Dragons have no influence whatsoever on the squares they leap. For example, a Dragon on d1, controlling the line d3-d5-d7-d9, would not stop an opposing Queen moving a6-h6, crossing at odd distance from the Dragon.

"On one other note, why promote your pawns to Knights rather than Unicorns?"

In order to promote to a Unicorn, you must have lost one of your starting Unicorns.

Man and Beast 02: Shield Bearers. Systematic naming of divergent coprime radial pieces.[All Comments] [Add Comment or Rating]
J Andrew Lipscomb wrote on Wed, May 22, 2013 09:32 PM UTC:
On the prefixes: given the four "basic" (European, Warhead, Ambush, Nonchalant) patterns of capture/non-capture allowed, we have prefixes for those with zero (Ancient), four (Eurofighter), or two (all six ways) powers. Missing are those with three. Proposals:

anti-European (must capture at least once): HUNGRY

anti-Warhead (may not capture twice): DIETING (no second helpings!)

anti-Ambush (if first is passive, second must be too): ELECTRIC ("It has to warm up... so it can kill you" of Wednesday Addams' electric chair)

Anti-Nonchalant (if first is capture, second must be too: ADDICTED (gotta keep killin'...)

Puzzle Shatranj. Shatranj on a 15 puzzle. (8x8, Cells: 60) [All Comments] [Add Comment or Rating]
J Andrew Lipscomb wrote on Mon, Dec 21, 2009 06:46 PM UTC:
You only have 15 pieces, so 'at-least-one' implies 'exactly-one.'

On the commentary, a piece with eight bindings is thrice colorbound, not four times (which would mean full coverage requires sixteen). At the fourth order, it is switching (as the Ferz is at the second order and the Knight at the first).

Alternate Promotion Chess. Pieces promoted at one end of the board are promoted further at the other. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

You have Cardinals promoting to Cardinals...

LiQi. Very Strong Chess. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
J Andrew Lipscomb wrote on Sat, Aug 29, 2009 01:48 AM UTC:
Isn't the running-leaf by definition stronger than a queen, since the queen is a subset of it? (That is, if the 'degenerate' planar move in which one side of the plane is 1 is an allowable move.)
And I can tell that the young-lion is not allowed to return to its original square (a limitation not shared by the Japanese lion), but there is one slight unclear point: is it allowed to make double captures?

Shogi 59. Shogi on half of a 9x12 board. (9x13, Cells: 59) [All Comments] [Add Comment or Rating]
J Andrew Lipscomb wrote on Fri, Jan 23, 2009 02:54 AM UTC:
Hmm... all pieces are colorbound, and both players have all their pieces on one color--which is not the same as the color containing the opponent's pieces... I don't think the two players ever interact! (Think you may have meant 9x13, which puts both players on the same color and gives you 59 cells of that color...)

Checker-capture Chess. Pieces can capture as in checkers game. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
J Andrew Lipscomb wrote on Wed, Dec 31, 2008 02:10 AM UTC:
Looking at rules 2 and 3 together, I assume this is the Russian-style multi-jump rule (no stopping if the piece has another jump, but you may take it in a direction that has fewer)?

Faster and Faster Chess. Pieces move one square, then continue two, then continue three... (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
J Andrew Lipscomb wrote on Fri, Oct 31, 2008 05:39 AM UTC:
I think the 'and then three' comment is redundant for the Knight, since six Knight-leaps in the same direction would require a board of 13 squares in at least one dimension.  Hmmm... using such a piece in a variant with a larger board, could the Rook and Bishop go 'and then four,' or is three the speed limit?

Come to think of it, a piece like this with a 'speed limit' of 2 might be interesting-- the Rookwise piece would be color-changing, while the Bishopwise one would remain colorbound, but switch Alfil-bindings... hmm, I just reinvented the Panda and the Bear.

Conclave Ecumenical Chess. Large variant with wide variety of Rook and Bishop compounds. (9x12, Cells: 108) [All Comments] [Add Comment or Rating]

'Ancress' is a pretty rare spelling. The more usual term is 'anchoress.'

I believe that by 'attack' he means 'capture.' Always tricky writing in a non-native language...

Hafts. A denser Draughts, but with pieces only capturing those bound to the opposite colour. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
J Andrew Lipscomb wrote on Wed, Jun 14, 2006 02:48 AM UTC:
Think of it as two games of checkers played at once, one on light squares and one on dark. (Thus, the starting setup is 24 pieces, solidly occupying the back three ranks.) Then change the pieces' capturing move to orthogonal instead of diagonal (straight ahead only for plain men, all four directions for crowned men)--so a piece in one game actually captures pieces from the other.

The Waffle is for some strange reason linked to the Gold General. It actually appears in Chu Shogi under the name Phoenix.

Recognized Chess Variant: Wildebeest Chess. Now a Recognized Chess Variant![All Comments] [Add Comment or Rating]
J Andrew Lipscomb wrote on Mon, Apr 3, 2006 05:36 PM UTC:
Keeping in mind, however, that stalemate is a win in Wildebeest Chess, can a Wildebeest or two Camels (or for that matter two Knights, or Knight+Camel) defeat a lone king with that rule in place?

You could easily play with knights instead of bishops--that would be Los Alamos Chess plus castling.

If the scoresheet provided is electronic, then that's what the players use. As for personal electronic scoresheets, you'd need a way to prove that they can't also be used as playing aids, but that done, the arbiter would be within his rights to declare that an accommodation for a handicap, I would think.

'Baring the king' (as it is traditionally called) does not end the game in standard Western chess--the player with the lone king cannot actually win (since there's no way to give mate with just a king), but can still lose or draw. If both kings are bared, of course, the game is a draw.

Actually, no English-speaking countries remain that use the 'long scale' where billion is 10^12. The British officially abandoned the 'British system' in 1974, although there are those who still remember/use it. The only unambiguous way of saying it is '100 million million' ::)
