Actually I don't believe Knights decline in value. For the very simple reason that they're not restricted by the edges or the corners. It's easier, therefore, to develop them.

Abdul-Rahman Sibahi wrote on Fri, Aug 24, 2007 09:41 AM EDT:
Ah, you're right. Knights are certainly not equal to Rooks in this game. But they do gain value from their ability to jump, AND Betza's leveling effect. If all the pieces were equal in value it would be a dull game, where people would exchange pieces and reach a pawn endgame.

Incidentally, I think the bishop, on a semi-open position, is stronger than the Rook on this board.

This is a diagram for the Nightrider's movement. The squares marked with & are can be reached by more than one path.

Yes, Graeme. Some 3D and hexagonal and triagonal (Sankaku Shogi, I think) boards were submitted to the previous contests.

Adding the Sideways Dabbabah to the Narrow Knight will achieve nothing important. The piece will be able to triangulate, but that's all there is. It's still 4-way colorbound.

However, adding the Forward and Backwards Dabbabah makes the piece 2-ways colorbound, but unable to triangulate.

Betza used the Ferz+Forward Knight (Fibnif) with success in the CwDA. The piece is as powerful as the knight, even though it's slower while moving from one wing to the other.

I believe he means it to be on the Standard 8x8 board.

I came across this variant while browsing in BoardGameGeek.com .

The idea of it is to play chess with out a board. The Chess pieces are
represented by tiles that must, at all times, be connected to each other.
(According to that page, it's a cross between Chess and Dominoes.) The
Game allows up to six players to play.

Is there a page for this game here? It certainly sounds like a crazy idea.

If you don't mind me saying, this is one hell of a mutator !!

However, it is probably difficult to keep track of everything going on at once, I would suggest three modifications, which may be combined or taken independently. My personal choice would be to use the first two, and discard the third.

1. Keeping pawns out of the sequence until they promote.

2. ONLY piece which more attacked than they are protected promote. That is, after 1. e4 e5 2. Nf3 Nc6 , the pawn on e5 doesn't promote because it is attacked once and defended once. The King could count here.

3. Limiting promotion to one piece at a time, no matter how many pieces left unguarded.

((I believe there is a mistake in the example game... in white's fourth move promotion details, if you would check it out.))

I nominate this game to be in the next Game Courier tournament (using modifications 1 and 2 above.)

Falcon Hexagonal Chess. The Falcon into the Hexagonal world. (Cells: 121) [All Comments] [Add Comment or Rating]
💡📝Abdul-Rahman Sibahi wrote on Sun, Sep 9, 2007 03:25 PM EDT:
Graeme .. Thanks for the rating and the diagram! And no, since the Falcon Chess patent only covers the Square version. (You might want to include the 'Gnu-instead-of-Knight' variant, but it's your choice.)

(Speaking of ZRFs, the variant in the following link might interest you as well.) Link

Thanks again ..

Joe,

Thank you for the comment.

As for the pawn structure, this game was intended as a re-modeling of Glinski's Chess to include the Falcon. So almost all the setup 'ideas' are borrowed from that game. As I understand the philosophy of Glinski's Chess, this setup ensures that all pawns are protected (they protect each other,) AND that all the pieces can move in the opening setup.

Your idea of the zig-zag line was used by Christian Freeling in HexDragonfly. It is probably just as workable as anyother setup. Link


Disintegration Chess. Win by disintegrating 3 Kings and having 1 left. (5x9, Cells: 45) [All Comments] [Add Comment or Rating]
Abdul-Rahman Sibahi wrote on Sun, Sep 16, 2007 11:31 AM EDT:
I don't quite understand how the disintegration works. I believe a sample game might help.

Abdul-Rahman Sibahi wrote on Sun, Sep 16, 2007 05:43 PM EDT:
So, technically, the goal is to 'check' all three kings to win ?

Nietzsche Chess. That which does not capture a piece, makes it stronger. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
Abdul-Rahman Sibahi wrote on Tue, Sep 18, 2007 05:51 PM EDT:
To explain my idea further :

1. Pawns are not promoted at all by the Nietzsche rule. However, when they reach the 8th rank, they are promoted as usual, and only then enter the promotion sequence.

2. After (1.e4 e5 2.Nf3 Nf6), the e5 pawn is attacked once, and not defended, so it is promoted to a Knight (assuming suggestion 1 is not in effect. Consider this : (1.e4 e5 2.Nf3 Nc6) the pawn doesn't promote, because it is now attacked once and defended once. If the game was to continue (3.d4 Nf6) the pawn at e5 promotes, because it's attacked twice and defended once.

-- 

The only objection I have about this mutator is its clarity. It appears to be difficult to see more than one move ahead. If both suggestions above are taken into account, it will make things a little easier.

I started doing that, but then FireFox crashed and the page closed .. if
you would please delete the current page so I can post it again.

Thank you, again, and sorry for the trouble.

Yes, Charles. The Dolphin can make his backwards move to a file containing another Dolphin.


I don't understand the logic behind the Porpoise though.

I am curious, is there a write-up for the rules of Great Whale Shogi anywhere online ? This would make a valuable addition to THIS website.

Bland Chess. Chess with no diagonal moves. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
Abdul-Rahman Sibahi wrote on Fri, Oct 5, 2007 07:32 PM EDT:
A better example Joe could've provided is Monochromic Chess, where all piece must land on the same color of the square they started from; i.e. Knights can't move. It's a famous fairy condition in problems. A pretty implementation of this rule into a game is Alice Liliputian Monochromic Chess (not sure about the order of adjectives) by, I guess, Peter Aronson. Check it out.

I don't think Bland Chess is the reason Chess players hate Chess Variants. I think the real reason is Bughouse, and that they are too narrow minded.

Abdul-Rahman Sibahi wrote on Mon, Oct 8, 2007 10:01 AM EDT:
Ok .. I do think there's a mistake in the problem. The only legal move for Uppercase is 1.e8(R,B,N) .. Whatever piece it promotes to, it can be captured by the Queen or the Rook, resulting in stalemate = draw.

I would suggest promotion to a Bishop. Threatening stalemate. But I can't see how white can avoid loss even afterwards.
