strange behaviour of PyturoChamp on WinBoard AA beta /CuteChess

[Norbert Raimund Leisner]

Hello ,

on WinBoard AA beta GUI http://hgm.nubati.net/WinBoard-AA.zip I use PyTuroChamp UCI https://github.com/mdoege/PyTuroChamp vs. Fairy-Max WB
(component of the WinBoard AA beta GUI) during a 40/5 min engine match.

example: after Fairy-Max played 1.Nf3, PyTuroChamp crashes immediately with "XBoard: Forfeit due to invalid move e7e6 (e7e6 via `0`0 ) res=24 0-1"

Python 3.7.3 https://www.python.org/ftp/python/3.7.3 ... -amd64.exe (OS: Windows 7 SP1 64 bit)
Engine (.exe) C:\Users\NRL\Downloads\Python37\python.exe
Protocol autodetect
Commandline-Parameters: ptc_xboard.py

It seems curious: A match human vs. PyTuroChamp under the same conditions proceeds without incidents 1.d4 e6 2.c4 Nc6 3.Nf3 h5 respectively 1.e3 g6 2.Nc3 Bg7 3.Qg4 d6 - PyTuroChamp can execute moves with the blackes or white pieces

It exists a Windows binary of course, but I want to test various PyTuroChamp "personalities" like Plankalkül, Shannon, SOMA, EL Ajecedrista (Torres)

Any suggestions? Is this phenomenon a Windows, GUI or engine problem? The author´s recommendation / first choice is CuteChess 1.0.0 https://github.com/cutechess/cutechess/ ... _setup.exe ......

A complaint about an illegal move is not a crash. But it is strange behavior, as e7e6 should not be an illegal move at all.

But, as always, not much can be concluded if you don't post the winboard.debug file that was created through running WinBoard with the -debug option when this occurred.

[Norbert Raimund Leisner]

WinBoard option: -debug, but I cannot find any debug informations. Can anybody of you reproduce the refusal of PyTurochamp ptc_xboard.py (not the Windows binary!) to execute further plies and claim "e7-e6" = illegal move?

[hgm]

The winboard.debug file should be in the same folder as the winboard.exe.

Note that it is WinBoard that judged e7e6 to be illegal. This is what makes it so strange.

I don't understand in your post, if you only have this problem in Winboard or in CuteChess too, because it says
2 games finished of 2 and then you post the one game with White?
BTW CuteChess in current state does not save a debug file at all, but may be you mean the debug window output?
(Even here currently CuteChess unlike CuteChessCli does not save the complete debug but omits the beginning)

Anyhow here a game of latest PyTuroChess master (2019-06-19) vs. Fairy-Max 5.03b with Black.

Note that I always use Inbetween for calling an interpreter for various reasons.
(one of them is, that I have a script for transforming the winboard.ini entries to a cutechess engines.json file
and I want to keep the exact name of engine/version in my naming convention in the first place and I don't
need to change anything for using it in both GUIs)

Moreover I used pypy3 here which is recommended by the author for speed.

I will test it now with current Winboard and newest UCI2WB.

Same setup in WB with Inbetween like above. (latest WB_AA and UCI2WB from 19-06-18)

I thought though it has meanwhile implemented some time management, but it seems one
has to adapt it manually via uci depth options. (need to check the src, but too lazy now)
With default it played all moves at depth 2 in CuteChess and WB.

This doesn't appear to show any of the problems encountered by Norbert.

In fact, now that I look more carefully to the result message, it appears that WinBoard rules a win for PyTuroChamp (black): the stated result is 0-1. That means e7e6 was received from Fairy-Max. Which makes it indeed an illegal move. So it seems the problem is with Fairy-Max or its communication with WinBoard, and that PyTuroChamp really has nothing to do with it at all.
