Regarding Knappen's [2010-02-04] Comment, I have not investigated mating with a pair of Wizards. I suppose that a pair of Spotted Gryphons will also be unable to force checkmate (in general).
Hello, Fergus. I hit the [Prt Scr] button after sending my latest move to Joe (less than 20 hours ago). The message sent to him mentions a grace period of 14 days and ends with: 'If you move before you run out of time, you will gain an extra two days.' So he was supposed to start off with more than 16 days on his clock. Yikes!
I would be happy to see both players in both games Joe has mentioned restart with ten weeks (70 days) credited. Whatever time advantage I held in the past is of no real consequence. - David Paulowich

(10x10, Cells: 100) [All Comments] [Add Comment or Rating]QUOTING CHARLES DANIEL FROM [2008-04-23] IN THIS THREAD: 'Thanks for the info George, I had no idea that the patent would cover the use of the Bison.'
[1] George Duke has never claimed to be the first person to invent or describe the Bison, a fairy chess piece which, for example, has been used by Sergey Sirotkin on a 7x7 board.
[2] George Duke has never claimed to be the first person to use a (preexistent) fairy chess piece in a new chess variant. In particular, in one played on a board with more than 64 squares.
[3] It is very bad form for George Duke to discourage the use of the Bison in chess variants on this site, by making statements like his [2008-04-22] one here: 'The particular embodiment where both sides use Bison here, one of hundreds, is therefore under coverage of USP5690334.'
I have no formal connection with this chess variant site, except for my participation in the occasional tournament and Chess Variants contest. In the interest of full disclosure, I will mention that I once received a free Omega Chess Set as the prize for third place in that contest. My opinions are my own. - David Paulowich
QUOTING GARY GIFFORD CONCERNING Falcon and Bison
When you want to use Mr. Duke's wonderful Falcon piece, but are concerned about the patent, you can either:
(a) kindly ask for Mr. Duke's permission
(b) simply use the earlier Bison.
The excellent Bison piece can move twice like a Ferz and then once like a Wazir (or visa versa) in an outward direction from its starting point. And it can jump! (the Falcon can't jump, but can zig-zag around in different ways, to give the appearance of jumping)
Anyway, the Bison is easier to use and would be my preferred piece, of the two.
QUOTING GEORGE DUKE CONCERNING Falcon Chess: Background and Patent Text Excerpts
USP5690334 is paired Bison on 8x10. Problemists' Bison, used once or twice in 1970's, is incorporated into CV for the first time in history, by law with the sentences, at third from last paragraph written in 1995, ''Another possible embodiment is that in which the falcon has the ability to jump or leap over an intervening piece, as the knight can.'' Bison. Leaping Bison. Leaper to (2,4) and (3,4). Never before done or realized as fitting like a jigsaw puzzle into Rook, Knight, and Bishop. Now to improve Bison further, we ever so slightly weaken her in the embodiment by far preferred. We make her a Darter with three pathways. Bison is the clue, as are the 15 or so compounds of (Knight + Camel) in 'ECV' (1994) and 6 or 8 compounds of (Knight + Zebra) in 'ECV' (1994) and two or three of (N+C+Z), as in 1920's Cavalry Chess by Frank Maus. Please call the patented reacher to the 16 squares beyond the Knight, any of Bison, Falcon, Snake, Phoenix, Spider, Octopus as you will. The patent is methods', for the method, as you would a chemical process, by comparison. Once some particular method of sequencing DNA is described, for one example within ''methods,'' it may not be so hard to duplicate the process, in a good laboratory. After the fact of discovery is much easier. But except for personal and friendly use, individual trial and error, it is the right exclusively of the proprietorship to do it publicly.
Gross Chess. A big variant with a small learning curve. (12x12, Cells: 144) [All Comments] [Add Comment or Rating]I think a Wizard is worth about the same as a Bishop - if you prefer taking 50 points off the Wizard and the Champion, that is fine with me. Just started my first game of TENCUBED CHESS last month, so the values are still untested theory.
Champions and Wizards were added to the GRAND CHESS setup in TenCubed Chess. WARNING: I recently added some comments to the Rules section of my 12x12 variant Rose Chess XII concerning forced mates by King and one piece against a lone King. The Champion can force mate on a 10x10 board, but often fails on a 12x12 board.
P=100, N=300, B=375, Wizard=400, Champion=450, R=600, A=850, M=950, Q=1100 are my best guesses for piece values in endgames on a 12x12 board. See the bottom of my ROSE CHESS XII page for some brief notes on theory. Interesting fact: my OMEGA CHESS certificate of ownership has notes on piece values (on a board with 104 squares) by Daniel Macdonald: Bishop=400 and Champion=400 are the only values that differ from mine. I usually value a Cannon equal to 70 percent of a Rook at the start of the game, lowering this estimate after each exchange to reach 50 percent by the early endgame. I assume that the Vao has the same numerical relationship to the Bishop.
Nilakantha's Intellectual Game. 17th or 18th century Indian chess variation. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]Garth make a valid point, so I will have to try again. Consider the BLOCKADE STALEMATE IN 20 MOVES shown in the following diagram. NOTE: this position is from a (legal) game of Shatranj, which started with the Kings on the d-file and ended with a White Knight capturing a Black Elephant. A mirror image of this game can be played in the 'Intellectual Game'. Now the Black King is imprisoned by his own pieces.

Unfortunately, I cannot find the time to play in a major tournament in 2010. Good luck to all of you!
Doug Vogel's Chess on a 12 by 12 board looks like NextChess to me. Just grab a checkered tablecloth and one of the millions of (classic) chess sets lying around! The Game Information Page should have links to my preset and Edge of the World Chess (identical opening setup, different rules) added.
We could always use Day After Tomorrow Chess for the category of near-future chess variants.

Alice Chess on a Courier Board [February 2023 proposal]
There is an old Game Courier Preset for Smaller Alice Chess on 32 squares. The two boards fit inside a standard 8x8 board. Why not expand my earlier game to a pair of narrow 6x8 boards, fitting inside a 12x8 Courier Chess board? The fortunate few owning such a board could set up postal games on it. While lacking the time and energy to playtest this game, I can at least leave you with the shortest Fool's Mate of any chess variant.

Following in Peter Aronson's footsteps, I am going to ramble on some more. How crowded the chessboard feels depends on several factors, including the number of pieces on the board and their Attack Density: calculated by adding up the number of adjacent squares each 'nonpawn piece' attacks and then dividing by the number of nonpawn pieces. Ruggero Micheletto's Ultra Chess achieves the maximum 8.00 by adding the King's move to every piece in the game (except Pawns).
Looking at some of my recent 10x10 variants: Opulent Lemurian Shatranj has Attack Density 4.00 (same as standard chess) and Shatranj Kamil X has Attack Density 2.50 (same as Shatranj). The latter game includes Cannons, which attack opposing Pawns in the initial setup. I don't know if that makes this variant more 'crowded', but it certainly adds to the number of threats on the board.
Silver Elephant Chess. Missing description (10x8, Cells: 80) [All Comments] [Add Comment or Rating]'Silver Elephants are leapers that can reach all squares on the board and can also be very nice and useful short-range attacking pieces. They are similar in value to the long-range color-bound Bishops and stronger than the leaping Knights.'
In Peter Aronson's White Elephant Chess this piece is called a Great Elephant. I would value this shortrange piece halfway between a Bishop and a Rook on a 10x10 board.

ATTENTION: my Raumschach Revised preset has the correct alternation of colors on a (slightly wider) Raumschach board. The initial setup and co-ordinate system match the game information page.
EDIT: the 3-D CHESS FAQ FILE offers more information on Raumschach. Also I added some COMMENTS regarding piece values and forced checkmates.
