Request to someone with sone (basic ?) compilation skills

[Yannik Snoeckx]

Hi !

As some or even most of you may know, the source of GnuChess 3.1+ is (and has always been ?) available at this site :
http://www.tim-mann.org/gnuchess.html

It is, if I am not mistaken, the first xboard/winboard programm ever !

Wouldn't it be nice to see how this 1991 champ fares against later competition ?

Could some kind soul compile it for modern systems, like (shameless self-interest) Windows XP ?

Many thanks in advance.

I don't believe version 3.1 had Winboard support. That was first introduced in about 1993. The sources for 3.1 are for a Windows GUI program (and it looks like maybe it is Windows 3.1 or that vintage - doesn't compile on a modern system).

I tried the more commonly available Gnuchess 4.0 a while back and found it was quite weak against recent engines, even amateur ones, especially in endgame.

I've just added basic winboard support.
The 3.1 sources I have are for console based engine and it compiles ok with cygwin-gcc.
Once I've sorted out the time control I'll post a link to it.

Hi

Guenther Simon's history pages say 1991 for the first release of GnuChess and in the readme of the source I've downloaded (link in the first post of this thread) one can read :

This is an update of gnuchess version 3.1.

It fixes all known bugs with pawn promotion, undo, and win/draw determination.

It adds the capability of reading xboard position files (xget).

It adds specification of save and load files on the command line (gnuchessr).

Save file format is now human readable.

'white' and 'black' no longer start play but only set the players. If the
computer is to move first use the 'go' command.


New commands are xget and hashlevel.

xget reads an xboard position file.

hashlevel allows you to specify parameters for using the hashfile.

So I believed it could already be winboard.

I tried the more commonly available Gnuchess 4.0 a while back and found it was quite weak against recent engines, even amateur ones, especially in endgame.

GnuChess 4.077 (1996) was quite strong for its time, but yes its endgame play is horrible (as for many other old ones). What more it has a bug in tournament control time and another one with uncorrect drawclaims.

Under the kinder (at least for it) rules of my dinosaur league (fisher clock, nunn positions, etc.) it stands quite well for its age, I think. Here's a little part of the standings :

Here's a new build of the original/unhacked by me, GnuChess 3.1 (console mode only)
version, which will run modern Windows systems. I thought I'd compile this for historical reasons.

Hi Jim,

We now have 2 engines named "Chess":

Chess 5-23-88 Rev 0.2 by John Stanback
and
Chess 2.9a by Evgeniy Korniloff
http://evgeniy-korniloff.narod.ru/download.html

Very confusing!

Ron

[Jim Ablett]

Hi Ron,

Yes, but John Stanback's was first. By twenty years! First version of Chess was released 1988.
I name Evgeny Korniloff's engine 'Chess One' because that's what it's called in the source code.

Jim.

[Jim Ablett]

There seems to be a fair few bugs in this early version.

Another update. This fixes a bug in sending the mate result correctly.

Chess 5-23-88 Rev 0.3 by John Stanback

[Jim Ablett]

Another bug found .... can't be many left now - I hope!

This update fixes a resign bug. (Engine would resign immediately after it had made it's move, instead of before)

Hi Jim

As usual, many many thanks for bringing these oldies back to life

I'll include both Chess and GnuChess 3.1 in my next Promo tournament.

Olivier

[Jim Ablett]

Thanks Olivier.

Both Chess 5-23-88 and GnuChess 3.1 are surprisingly quite strong
for their age. They must have been quite something when first released.
GnuChess 3.1 has ponder capability, which I've just discovered. My next
task will be to get it working correctly in the winboard version, it's not enabled at the moment.

best,
Jim.

Hi Ron,

Yes, but John Stanback's was first. By twenty years! First version of Chess was released 1988.

I agree completely. No new author should use the name of an older engine!

We have the same problem with the name 'Chaturanga.' If the original Chaturanga source becomes available there will be another problem!

I wonder if there are other engines with duplicate names?

I name Evgeny Korniloff's engine 'Chess One' because that's what it's called in the source code.

Jim.

When I run Evgeny Korniloff's engine in console mode, it prints "Chess" as the name. I don't have access to the source code, so I will change my information to 'Chess One' based on your observation. But maybe 'Chess Two' would be more accurate!

One of the reasons for the Private Engine List is to reserve names for future chess engines. The list also exposes naming conflicts in advance of a public release.

In my opinion: When there is a conflict in names, the original program is the one that gets to keep its name and the newer one using its name gets renamed!

Thanks, Jim!

Thanks Jim; i like GnuChess and these versions are of collection.
Maybe Chess 5-23-88 might be named GnuChess 5-23-88 or GnuChess 1.0.

Hi Ron, Brainless isn't private anymore.
