Ufim 8.02 FRC bug (please forward this to the author)

[Volker Pittlik]

At the moment I'm playing around with FRC engines a bit.
Ufim 8.2 is on of the newest and I give it a try.

Starting it with the FRC enabled xboard version I got the error message:

volker:~> xb960 glaurung-1 ufim-2 -lpi 1 -mg 2
xboard-960: Variant fischerandom not supported by Ufim 8.02
volker:~>

Starting Ufim at the commandline and in the log I found:

Code: Select all

Ufim 8.02 (July 2006)
hash size = 32 MB
xboard
protover 2
feature done=0
...
feature myname="Ufim 8.02"
feature variants="normal"
feature colors=1


Therefore xboard's reaction was absolutely correct.

It should be:

Code: Select all

feature variants="normal,fischerandom"


It would be nice if someone xould forward this report to Niyaz because our ISPs don't like each other and I can't reach him by email. Maybe he could try vpittlik (AT) arcor.de instead.

Homer 1.02 Linux provides also an uncorrect variant string.

Hi Volker,
Ufim and Homer have implemented UCI-SMK-style FRC.
Maybe WB-Arena-style FRC is not implented.
Only BigLion, Taktix and ChessGUI know all 3 styles (including UCI-Arena-style).
Best,
Matthias.

Oops, didn't found it although it is clearly in the readme. Thanks.

Wimm start a small FRC tournament soon.

I only use the UCI style (HAha). I made a test with BigLion and Taktix with wine under Linux and they both seem to run.

I write seem because I'm running a small tournament and have to face some unexpected problems. BigLion and Taktix will run a gauntlet after the tournament.

Unfortunately there are no FRC engines weak enough for BigLion
to beat, so a gauntlet would only test stability .
BTW, some FRC engines malfunction if Ponder = ON.

I didn't noticed that so far. Pharaon makes out-of-turn moves when playing here. But I guess this has something to do with using it with wine.

The same is unfortunatly true for Taktix: it doesn't quit at game end.
More bug reports and results to follow.

BigLion and Taktix have never misbehaved here, and they play FRC often.
Only Jonny has never worked correctly.
I use ChessGUI and Windows 2000 Pro.

I predicted that. I wrote before I run Linux and use wine to play the Windows progs.

I couldn't find the reason why it sometimes works and sometimes not. Spike for example played 30 games in a row without any problem yesterday. Today I have to kill it every time manually. Not a good idea to let them play over night or weekend unattended.

You are right. Ufim 8.02 supports UCI-only FRC.
By the way, where can I find the protocol specifications for WB-Arena-FRC and WB-Xboard-FRC ?

I think WB-Xboard-FRC is using the UCI specifications which can be found at the end of this document: http://download.shredderchess.com/div/uci.zip.

I don't know is there is a document for the Arena variant somewhere. I got it once by inspecting the debug information there. X-FEN can be found by google.
