Strictly for Chess960 Enthusiasts ...

MikeB · Post by **MikeB** » Tue Jun 25, 2019 7:01 am

wrote a little program designed for Chess960 enthusiasts today, less than 100 lines of code - it can do several things ..

first, enter the Chess960 non-zero position number , and it will return the FEN with the PGN style tags that are required for Chess960, FEN, setup and variant, suitable for adding other flags or in xBoard ,just copy the 3 tags and paste>game and there is no need to make sure it is set to Chess960 prior to pasting

second, enter a negative number and it will recognize that you are asking for some random Chess960 positions generated and it will ask you for how many

third, enter 0 (zero) and it will recognize you are asking for a complete dump of chess960 positions in order

Also attached below is the complete log for the snippet - was just curious if anyone would be interested.
If so i can get binaries made for all flavors of OS.
You can just reply here if interested - if there is a large enough response, I will provide binaries to those interested.

terminal based , written in c, sample output, redirecting output to a file:

The position formula used was from this, I am not sure who actually came up with this, but I found it here and the results match with xBoard and ICCF:
https://en.wikipedia.org/wiki/Chess960_numbering_scheme

Code: Select all

/*
White's Chess960 starting array can be derived from its number N (0 ... 959) as follows:

a) Divide N by 4, yielding quotient N2 and remainder B1. Place a Bishop upon the bright square corresponding to B1 (0=b, 1=d, 2=f, 3=h).

b) Divide N2 by 4 again, yielding quotient N3 and remainder B2. Place a second Bishop upon the dark square corresponding to B2 (0=a, 1=c, 2=e, 3=g).

c) Divide N3 by 6, yielding quotient N4 and remainder Q. Place the Queen according to Q, where 0 is the first free square starting from a, 1 is the second, etc.

d) N4 will be a single digit, 0 ... 9. Place the Knights according to its value by consulting the following table:

Digit	Knight positioning
0	N	N	-	-	-
1	N	-	N	-	-
2	N	-	-	N	-
3	N	-	-	-	N
4	-	N	N	-	-
5	-	N	-	N	-
6	-	N	-	-	N
7	-	-	N	N	-
8	-	-	N	-	N
9	-	-	-	N	N
e) There are three blank squares remaining; place a Rook in each of the outer two and the King in the middle one

A little outdated, but nice site.

However, the output is missing the PGN tag "Variant Chess960". So when it is copy and pasted into GUI that understands Chess960 (xBoard as an example that I tested ) , the GUI does not know its Chess 960 and prevents you or the engine from castling ( returns a n illegal move error). Also it would be nice to know the Chess960 Start Position number. xBoard simply ignores the extraneous tag when pasting game. It will however , automatically switch to Chess960 mode.

Output from current version when selecting 10 start positions at random. Even if you select 959 start positions ( from the 960 positions) at random, none will be duplicated. Dates will be automatically be updated based on when you run the program.

  Enter the non-zero based 960 position number 1 through 960, enter zero to dislay all
  Chess960 starting positions in PGN format, enter a negative number less than -1 for 960 positions
  chosen at random, or enter -1 to exit.
  Any mumber greater than 960 will return all Chess 960 positions in raw FEN format:

-5
You entered -5, a negative number, indicating you wish to generate one or more random Chess960 positions.
How many random Chess960 positions do you wish to generate?
10
You entered 10, Chess960-Lookup will generate 10 unique random positions.

If you prefer just the fens, that can be generated as well (sample out put below).

Code: Select all

990
You entered 990, a number greater than 960, all 960 FENs will be displayed in sequence.
Enter 0 (zero) to generate in sequence, any other number will sort the output randomly.

It works perfectly for engine matches with Cutechess, Shredder GUI and ChessGUI,

It is used as an openings pgn for engine matches, not copied and pasted. I've played over 200,000 games with this method so I assure you it works. That pgn originally came from Stefan Meyer-Kahlen in fact.

That's fine - so I assume, that in some manner, then you are telling the GUI that it's playingChess960 - my tool is for a human player. It was not a tool design for engine matches at all.

You don't have to tell Shredder GUI it is a chess960 match you want to run because it recognises the FEN. With Cutechess and ChessGUI you do tell it.
