Fischer Gothic
By: GothicChessInventor Date: January 19, 2018, 1:56 pm
---------------------------------------------------------
I decided to make an extended version of Gothic Chess to mark
this, the 10th anniversary of the death of Bobby Fischer.
[attachimg=1]
From left to right, the pieces are:
Rook
Unicorn (Knight that can hop 2 or 3 moves before making its 90
degree turn)
Archbishop (Bishop + standard Knight)
Bull (Bishop + Unicorn)
Chancellor (Rook + standard Knight)
Queen
King
Chancellor
Bull
Arcbishop
Unicorn
Rook
Castling: King moves 4 squares.
All pieces must be moved between the king and rook, and no
squares the king crosses can be threatened.
Pawns: 1, 2 or 3 moves on the first turn. 2 moves permitted on
the second turn if moved once on the first turn.
One level of en passant if passing by any pawn that has moved a
total of 4 squares from its starting location by moving 3 moves
to bypass it.

For those who would like to try it out against Fairy-Max,
placing the following game definition in the fmax.ini file
should do it. The piece values are just guesses. I decreased the
A and C a bit relative to Q compared to the normal Gothic Chess
values, because I supposed that their short-range N component
suffers more from the larger board than the Queen's slider
components. In addition I downgraded the Archbishop a bit for
the more unfavorable board aspect ratio (closer to a square),
which is bad for diagonal slides. Despite that, the Q-A
difference is only 125cP, which would make the Bull (which has 8
extra leaps compared to A) by far the strongest piece on the
board.
To play it, select 'fischer-gothic' from WiBoard 4.9's New
Variant dialog.

Thanks H.G.! I was struggling with how to do this and now you
did it for me. And I am running an engine self-play game right
now.

Is there a way to change the icons for the pieces to make them
look like the pieces Zied has (shown in my first post)? That
"bull" in fmax looks so much like the GNU free license icon :)

You caught me there! :)
XBoard does not have a bull in its default piece theme, and the
Gnu was as close to bovine as I could get. The Knight-Camel
compound that you use here as Unicorn is more commnonly known as
'Gnu', and since XBoard is an official GNU project, I figured it
should support this Gnu!
You can pick another image from the default piece theme by
putting the C and c in another position of the pieceToChar
string in the first line of the game definition. The viking
helmet is the only other thing with horns, however...
Of course WinBoard allows you to provide your own bitmaps. This
is actually what the WinBoard-AA package does: instead of using
its own set of built-in bitmaps, I shipped a set of XBoard piece
images with it, in the folder 'bmaps', and then configured
WinBoard to use those as external bitmaps. They are basically
the same pictures (in so far WinBoard has them as built-ins),
but the XBoard images are anti-aliased renderings of vector
images, with transparent background. You could provide your own
set of images instead. Or just replace the file that contains
the Gnu image by one with another picture.
Fairy-Max doesn't get to search very deep, on a board this big.
I guess it really hurts that it scans the entire board in every
node to find its own pieces. So it is probably not very strong.
But it should still be a nice sparring partner to get an
impression of how the variant 'works'.

I get to plies 9 and 10 on my machine which is pretty
impressive.
But, there is a bug.
[attachimg=1]
You can see the program wants to play Archbishop x Bull by
moving as a bull, but it is only an Archbishop. And fairymax
reported its own illegal move!

Ugh. It seems I made a copy paste error when shuffling the
pieces in the desired order, and the definition of the
Archbishop and Bull became the same. The line
[font=courier]a:825 15,3 17,3 -15,3 -17,3 14,7 31,7 33,7 18,7
-14,7 -31,7 -33,7 -18,7 13,7 47,7 49,7 19,7 -13,7 -47,7 -49,7
-19,7[/font]
should have been
[font=courier]a:825 15,3 17,3 -15,3 -17,3 14,7 31,7 33,7 18,7
-14,7 -31,7 -33,7 -18,7[/font]
I.e. just 4 diagonal slides and then 8 hippogonal leaps. The #
line that tells WinBoard how the piece moves was correct (BN),
so once Fairy-Max decides to place the (3,1) leap it thought
this piece had, WinBoard flags it as illegal.

I just made the fix and decided test the program this way:
[code]
1. Pawn e1-e4 Bull d8-e6
2. Archbishop j0-i2 Bull e6-f3 checkmate!
[/code]
So it seems to be working :)

The first fairymax selfplay game of FischerGothic ended in a
draw.
While most draws are boring, this one featured forcing a
repetition draw to avoid a deadly revealed check by the enemy.
