If somebody knows how to run this engine under Arena and 64-bit Windows 10, please share the secret with me. Even with the command line left empty (no syzygy) it does not move.

Hi Gabor,

Thank you for testing my engine in Arena, I must admit I had not.

I've downloaded Arena, installed my engine as normal (type .jar, select the jar and it loads automagically) but I also found that the engine did not start moving.

I've analyzed my engine output and I see that the engine is not getting a command that it's expecting (namely 'go'). I'll try to fix this shortly but meanwhile there is a workaround:

1) if you want to play black you can use the ctrl-z shortcut to issue the 'go' command to Frank-Walter, and it will start with the white pieces
2) if you want to play white, you can just move, but the engine doesn't react without the 'go' command and the ctrl-z shortcut doesn't work then. The workaround is to press F4, go to commands and choose to execute the 'go' command from there.

I hope that helps for now and I will try to make an Arena compatible version soon:-) I have not tried yet if there is a workaround for tourneys :-(

Actually, and this is a bit embarrassing, I seem to have problems under all GUIs since I made some changes to the interface code to fix some timing issues. I just never tested playing a game against my own engine. Tourneys and matches in winboard and cutechess work perfectly.

All the more reason to quickly fix this!

Thanks for your patience,

I was able to run Frank-Walter 2.2.1 in Arena by using WB2UCI. I am not 100% sure I am using the correct command line options, but this is what is in my wb2uci.eng file:

Code: Select all

[ENGINE]
Name=Frank-Walter 2.2.1
Author=Laurens Winkelhagen
Filename=Wb2Uci.exe

[OPTIONS]
Program=java -jar -Xms150m -Xmx1024m frankwalter.jar -tt 24 -tb C:\Games\Chess\syzygy
; See Wb2Uci.html for more options
Version 2.2.0 works for me in Arena with just a simple batch file.

Thanks for the reply Laurens, I'm looking forward to the fixed version.

Gabor

BTW, is the name FrankWalter or Frank-Walter or something? We used JanWillem with your old engine.

Hi Gabor,

The fixed version is released:-) It can be downloaded from computer-chess.org

http://computer-chess.org/doku.php?id=c ... lter:index

About the name: FrankWalter is fine, it looks more natural to me anyway. Frank-Walter is the historical spelling to be honest;-)

Actually I saw that in CCRL 40/4 the name is also typed as FrankWalter.

Thank you,

It worked for me in a quick eng vs eng match.

I wonder if it is a java version problem again. I have j8 and j11, maybe the path points to the wrong one.

EDIT: I have just checked and my Arena uses the 8.191 version.
