Two new Ajax pieces are:

Ajax-Archbishop:

The Ajax-Archbishop moves like Bishop+Knight, plus it has one orthogonal non-capturing 'adopted' step.

Ajax-Chancellor:

The Ajax-Chancellor moves like Rook+Knight, plus it has one diagonal non-capturing 'adopted' step.

These two pieces are use used in the variants: Ajax Modern Random Chess (9x9) and Ajax-Capablanca Chess (10x8)

How to Generate OTB Random Positions. How to generate random positions?[All Comments] [Add Comment or Rating]
💡📝Jose Carrillo wrote on Thu, Aug 6, 2009 02:30 AM UTC:
Thanks for your comment Thomas.

As I said this was by no means an all inclusive list of processes for randomizing positions.

It was meant to have a stake in the ground on generating random positions for OTB games, and a place to comment on other methods, probabilities, etc. about random positions.

I agree with your comment on the same color Bishops.

The reason of some of my options is to keep the process simple with handy equipment.

Of course if everyone (like myself) carried a 10-sided dice around then matters would be a lot easier for randomizing.

But the fact is that a 6-sided dice and a couple coins are easier to find, so I setup simple procedure accordingly.

Remember these procedures are intended for OTB games.

How many random OTB games do you expect to play in one sitting? Not enough to matter.

The Archbishop symbol I'm currently using in Ajax Modern Random Chess is misleading for the actual movements of the Ajax Prime Minister.

Ajax-Archbishop:

The Ajax-Archbishop moves like Bishop+Knight, plus it has one orthogonal non-capturing 'adopted' step.

Ajax-Chancellor:

The Excalibur program must have a bug. Castling is legal in that position.

Or you havenèt reset the castling flag or something like that on the Excalibur (I donèt own one, so I donèt know).

BTW, your Be3 moves are illegal in that sequence you provided, Bd3 is the correct move.

Your c1-Bishop (the one that actually can reach e3) is blocked by the d2-Queen.

My two new images can be used by chess variant creators however they want, if it makes sense according to the rules of their particular game.

The pieces I'm using in my Ajax variants just make logical sense as to the direction of their movement, but one must always remember the rules.

If I had to create new Ajax figurines, I couldn't play my Ajax variants OTB, which I do. I use a regular chess set, and elephants to represent the Ajax Ministers. Keep it simple!

My OTB opponents just know the rules, and know that the orthodox rook that they have always used in standard chess, in the Ajax games can move, but not take, one square diagonally.

Last time I checked my new pieces hadn't been aded yet to the Alfaerie Many set. Who else besides Fergus can help me with this?

Gracias Carlos!!!

💡📝Jose Carrillo wrote on Sun, Sep 27, 2009 11:15 AM UTC:
Yes Charles, thanks for clarifying your thoughts.

Cool then! My Ajax pieces are a unique original invention then! :-)

This is one of the reasons why I didn't want my Ajax Rooks, Bishops and Knights to be able to capture with their 'adopted' moves:



This position is from an Ajax Chess game after 5.Bc1-i7 with the Bishop pinning Black's Knight.

Should the Black Knight be able to capture on it's one-square 'adopted' moves, this type of pins would be impossible, for ... Nxi7 would remove the threat.

In my opinion this would make the game boring, and eliminate some of the chess tactics we are accustomed to.

To play with Rooks that capture like a Ferz, Bishops that capture like a Wazir and Knights that capture like a king; try Ruggero Micheletto's Ultra Chess.

Silver Elephant Chess. Missing description (10x8, Cells: 80) [All Comments] [Add Comment or Rating]
💡📝Jose Carrillo wrote on Fri, Oct 2, 2009 10:59 PM UTC:
Thanks David.

I wasn't aware of White Elephant Chess or the Great Elephants.

I stand corrected I my evaluation of the strenght of the Silver Elephant.

I based my statement more on my short experience playing with the Silver Elephant and the Bishop on the same board, than empirically.

While the feeling from my short experience playing the Silver Elephant was that they were both similar in value.

Mathematically, these are my value estimates on a 10x10 board:

Bishop 3
Rook 10.5
Queen 16
Knight 5
Silver Elephant 4

What I was surpise to find out was that the Silver elephant was weaker to the Knight.

Janggi - 장기 - Korean Chess. The variant of chess played in Korea. (9x10, Cells: 90) (Recognized!)[All Comments] [Add Comment or Rating]
Jose Carrillo wrote on Tue, Oct 6, 2009 02:45 AM UTC:
Yes, you can use the 'swap' command.

Look at the text at the bottom of the Korean Chess Preset page:

= = =

To swap Elephants and Horses at the beginning of the game, use the swap command. For example, this will swap Elephants and Horses on both sides for Red, then move an Elephant. Follow each swap command with a semicolon, and use coordinates for its arguments. Use it only before your first move.

swap b1 c1; swap g1 h1; E b1-d4

Thanks Tu Ren Dong.

Is it still legal to swap the Knights with the Elephants on the corners?

Here is a Game Courier preset for the North Korean setup:

Jose Carrillo wrote on Tue, Oct 6, 2009 03:14 AM UTC:
You are right Nicholas.

I tested the swap command and it was banned. Fergus can you fix it? Thanks.

Meanwhile, this preset for Korean Chess:

Doesn't enforce any rules, and will allow to swap the pieces.

>>How to procure the nice pieces shown on Jose Carillo's photograph on
>>this comment page? Thanks.

Jean-Louis Cazaux,

My pieces just come from a regular plastic set of chess pieces.

The Elephants are Seirawan Elephants.

For the Cannons, I cut off the top portion of the Rooks from a 2nd set (I kept the top of the Rooks to glue on to Knights to make Chancellors).

Finally I drilled holes on the headless Rooks to make them look like Cannons.

Cheers,
Jose

The Cardinal (called Prime Minister) was used by Gabriel Maura in his 9x9 game Modern Chess, invented in 1968.

This page is dedicated to the Prime Minister (Cardinal, Archbishop, Centaur, Adjutant, Equerry, Hawk and Janus):

Please let me know of interesting postitions with the Cardinal in action so that I can post them on the Prime Minister's page.

I just bought this same set today! at Korean Town, Toronto, Ontario, Canada.

I bought it at a P.A.T. supermarket near Bloor St. West & Euclid St.

The pieces are sold separately from the board.

The plastic Changgi pieces are sold for $3.99 CAD, the board for $16.99 CAD featuring Changgi on one side and Baduk (Japanese Go) on the other.

The Go stones were $10.99 CAD for the (white and black) set.

The board and piece are all very good quality.

The web site on the outside of the box for the board: www.6brothers.com

Nick,

I noticed what you meant about the painting finish.

I was wondering of the white dots myself. I figured that as part of the process of creating the pieces they were being held there (at the dots) by some other plastic sticks when the pieces were painted. The other side has no white dots. I'm planning to just paint the dots red and green myself.

If you find a nicer set of pieces (maybe made out of wood, but sold separately), yes I'm still interested.

I do not need a new Changgi board though.

Thanks.

Enjoy Korea!

Jose

I consider my Ajax army to be 'simple' in nature.

Just add the moves required to give pieces a Courier Man (Commoner) reach, and you get very interesting 'new traditional' pieces.

These extra 'adopted' moves are non-capturing to not upset some of the tactics (i.e. pins) we are used to and to allow the King a fair chance to defend itself against minor pieces in endgames.

The Ajax Chess complex includes: Ajax Chess (10x10), Ajax Random Chess (8x8), Ajax Modern Random Chess (9x9) and Ajax-Capablanca Chess (10x8)

Can a Korean speaker tell me what this would sound like in English? Thanks.

Thanks Yu Ren Dong.

Whats the Korean McCune–Reischauer or Revised Romanization for the Korean characters you provided?

Does 'Korean Random Chess' make sense in Korean?

Would it be better to say 'Random Korean Chess' or 'Random Changgi' instead?

Thanks Yu Ren Dong. Can 'Random Janggi' (below) also do as a valid Korean translation?

Hi Antoine Fourrière, (or Fergus),

Can you please add my two new pieces below for the Ajax Silver Elephant to the 'Alfaerie: Many' piece set?



It's a Silver Elephant that can move one (non-capturing) step sideways or backwards.

Thanks.

💡📝Jose Carrillo wrote on Sat, Oct 31, 2009 05:52 PM UTC:
Thanks Antoine.

Sorry to bother you again, can you please add my new Ajax Falcons too?



They have the combined movement of a Korean Elephant, Korean (or Chinese) Knight and Wazir, plus the characteristic Ajax one 'non-capturing' step in the remaining diagonal directions.



Ajax Falcons are improved Korean Elephants, which move one orthogonal step plus 2 diagonal steps. All squares in the path of the Korean Elephant must be unoccupied for the Elephant to reach it's destination.

The Ajax Falcon is not a leaper, so just like the Korean Elephant must also have the path clear to reach the 2nd diagonal square (labeled 3 on the diagram), but the Ajax Falcon can also move and capture at any square along the path to their 3rd square.

Therefore the Ajax Falcon can stop at their 1st diagonal square (labeled 2 on the diagram), provided the first orthogonal step is empty; giving the Ajax Falcon the Korean Knight move capability.

The Falcon can also just move and capture on it's first orthogonal square (labeled 1 on the diagram) in the path of it's Korean Elephant move, just like a Wazir.

Finally the Ajax Falcon has a one 'non-capturing' step in the remaining diagonal directions (red circles in the diagram), like a Ferz, to complete the one-step movement characteristic of the Ajax pieces.

Thanks.
