Modern Chess. Variant on a 9 by 9 board with piece that combines bishop and knight moves. (9x9, Cells: 81) [All Comments] [Add Comment or Rating]

Jose Carrillo wrote on Sun, Apr 6, 2008 11:58 AM UTC:

Thanks for updating the Modern Chess page with the Bishop Adjustment rule.

I found two typos.

1. The notation for the Bishop and Minister's Knight example is actually
B=MN (I made a mistake before with B=MK).

2. The international organization created that arranged tournaments and
world championships for Modern Chess was FEMDAM. (not FENDAM as Pritchard
incorrently quotes in his book).

FEMDAM = FEderacion Mundial De Ajedrez Moderno

which is Spanish for 'World Federation of Modern Chess'

Can someone please update the two typos in the Modern Chess page?

Can one of the admins for the site update the links at 

http://www.chessvariants.org/index/mainquery.php?type=Any&startswithletter=M&orderby=LinkText&displayauthor=1&displayinventor=1

to include a link to the Modern Chess preset for Game Courier?

The Modern Chess preset's link is:
/play/pbm/play.php?game%3DModern+Chess%26settings%3DAlfaerie

The 'See Also' page for Modern Chess:

http://www.chessvariants.org/index/displayitem.php?itemid=Modernchess

needs also to be updated with the link to the Chess Courier preset above.

Thanks in advance.

How does one become a Contributor to Chess Variants?

I have a new Bishop Adjustment Rule that I want to publish (next to Carlos Cetina's BCR rule), and I have 3 news variants that I've created that I also want to publish.

I have developed a more generic Bishop Adjustment Rule for the new Modern Random Chess variation.

My new Bishop Adjustment Rule also applies to Modern Chess:

Admins,

Can someone please update the Query page on 'M' items below:
http://www.chessvariants.org/index/mainquery.php?type=Any&startswithletter=M&orderby=LinkText&displayauthor=1&displayinventor=1

to include the Modern Random Chess Game Courier preset:

Thanks.

Hi Admins,

A corrections for the What's New Page:
http://www.chessvariants.org/index/whatsnew.php

For the week ending May 14, 2008 there are two Game Courier Presets entries for Modern Random Chess.

The one that says Author Jose Carrillo, Inventor Gabriel Maura, is actually for Modern Chess (not Modern Random Chess). The other one is OK.

A request: for the informational page for MRC64, can you add the text description 'Modern Random Chess 64' next to the link? (just like it was done for the MRC64 Game Courier Preset entry).

Thanks.

Capablanca's chess. An enlarged chess variant, proposed by Capablanca. (10x8, Cells: 80) (Recognized!)[All Comments] [Add Comment or Rating]

Jose Carrillo wrote on Sun, May 18, 2008 01:44 PM UTC:

Hi H.G.

Here is another 10x8 variant option for your engines, a random setup with the Four 'Modern' Chess Principles:

There are 151,200 possible starting positions!

The Four 'Modern' Chess Principles are:

The option of having both Bishops start up on squares of the same color

Reverse Symmetry
Symmetric Castling to either side (Players must agree before the game which type of castling [short or long] will they use in the game)
- O-Ob is Kb1 & Rc1 [Kb8 & Rc8 for black]; or O-Oi which is Ki1 & Rh1 [Ki8 & Rh8 for black]
- O-O-Oc is Kc1 & Rd1 [Kc8 & Rd8 for black]; or O-O-Oh which is Kh1 & Rg1 [Kh8 & Rg8 for black]
The Bishop Adjustment Rule giving players the choice (if they want) to change one of the Bishops to the opposite color squares in those setups where the Bishops start off on the same color.

Here is a sample preset for 'Modern Capablanca Random Chess'.

PS-I submited the comment below on the subject of the Four Modern Chess Principles. The comment below can be deleted.

Mastodon Chess (8x10). Standard pieces plus two Mastodons per side. A strategical big-board variant.[All Comments] [Add Comment or Rating]

Jose Carrillo wrote on Mon, May 19, 2008 11:35 AM UTC:

Why is the setup of the Knights and Bishops different from White to Black?

White has both Knights next to the King and Queen, Black doesn't.

This position is not symmetrical. 

Is there not a one sided advantage with this setup?

H.G.

Have you tried the Modern Capablanca Random Chess viariant with your engines?

H.G.

Thanks for your feedback.

Don't neccessarily agree with it, but I apreciate it.

Thanks Sam for the link to the different setups. It's a good reference.

My Modern Capablanca Random Chess allows all 151,200 possible Capa setups (those that still allow castling), including those with Bishops starting on the same color.

The Emperors Game is one of the original variants to display some of the 'Modern' principles: Reverse Symmetry and symmetric castling to either flank of the board.

Pawn (Xiangqi). Moves and captures one square straight forward.[All Comments] [Add Comment or Rating]

Jose Carrillo wrote on Sat, Jun 21, 2008 12:25 PM UTC:

Not sure what you mean by extra move.

When the pawn crosses the river, it gains the ability to move and capture sideways.

It still can't go backwards.

Symmetric Sissa problem. Problem based on an actual game.[All Comments] [Add Comment or Rating]

Jose Carrillo wrote on Mon, Jun 30, 2008 04:51 PM UTC:Excellent ★★★★★

Solution:

1. ... Sg3+ (c5-e3-g3 / g3-h2-h1)

The White King is in check, and only has 2 moves Ki1 and Kh1 [the g1 square is under attack by the g-Sissa (g3-e1-g1)]


2.Ki1 Sfxi2# (f8-i5-i2 / i2-h2-i1)

The i-Sissa checks on i1, and attacks h2 (i2-i1-h2); the g-Sissa protects the i-Sissa (g3-h2-i2) and attacks h1 (g3-h2-h1); mate!

or if:

2. Kh2 Sfxi2# (f8-i5-i2 / i2-h1-h2)

The King is in check by the i-Sissa, and he can't take either of the Sissas with the King as he would be in check by the other Sissa 'after!' the capture (note that the Sissas do not have a path to protect each other until the King moves out of h2, which it can't as he would be in check).

The Sissas attack all the possible squares for the white King:

g3 -> i-Sissa (i2-h2[once the King moves]-g3) -> This path protects the other Sissa
i2 -> g-Sissa (g3-h2[once the King moves]-i2) -> This path protects the other Sissa
i3 -> g-Sissa (g3-i5-i3)
g1 -> g-Sissa (g3-e1-g1)
h1 -> g-Sissa (g3-h2[once the King moves]-h1)
i1 -> i-Sissa (i2-h1-i1)

Thanks for the info on Mir Chess 32 and Midgard Chess.

I'll add them to the list of games with reverse symmetry.

I found this link on Thai Chess:

which explains the rules of the game, including the rule about how many moves does a player have to checkmate a lonely King before a forced draw.

Jose Carrillo wrote on Thu, Jul 3, 2008 09:48 AM UTC:

No problem. I'll change it.

I found a piece with 5 dots in the direction of movement of the Thai Bishop (I think it may be a wizard?).

What's the graphic for a Silver?

Give me a game that currently uses it so that I can see it and change it again.

those positions with Bishops in same color squares:
