10.10.3 always plays same opening . . #27
Comments
In my PC, with no options in the Initial moves tab, with Deep Toga and time 3s = always d4, with depth 1..3 =d4 You can run toga directly, then write uci, then go movetime 1000, .... |
And yet: (1) were this the case, the engine would be a bad one; (2) this was not the case with an earlier version of Lucas Chess that I had. This problem, and the seemingly 'close-happy' attitude on this bug-tracker, are inclining me towards abandoning Lucas Chess - and ceasing to recommend it to people. |
I have done the same test again, and deep toga select d4 with depth1, with time=3 d4, with 20 seconds thinking = e4, never Nf3, that is also a good open. I need to replicate the problem, but in this moment I can´t. It is necessary more information.
Sorry it is not my intention to disturb you, I have not much experience with this support and obviously it is an error. Then please help me to undestand the problem, then you decides the better you consider. |
If I may respond - even though the issue is marked - closed: good; please tell me what information you would like me to provide. I have the problem on both Windows and Linux (though admittedly that comes to the same thing really, since the Linux version is running in Wine because the native Linux version is, I am afraid, basically broken). |
I have reopen the issue, the other day I´ll try to reopen, but I can't. In relation to Linux, it is not supported in this version. Today I have tried to fix a problem that I believe doesn´t have a solucion in Linux, about minimize/maximize in the main window. Other issue you report. |
The Texel log is the next:
g1f3 = Nf3 is the decision of engine, nothing to do by the GUI. The reason to select always Nf3 by Texel is the use of a fixed depth. But something is wrong, because if you select intermediate level then the engine must work in analysis mode, I will fix it. |
Hi, I'd like to help with this issue if I can. Thanks. |
Dear fonkap
That's good of you; but I think a bug has been acknowledge and is being
worked on. (See Lucas Monk's comment in the post above: 'But something
is wrong, because if you select intermediate level then the engine must
work in analysis mode, I will fix it.')
Still, here is the explanation of the discepancy that you noticed. I did
say that Deep Toga (well, I wrote 'Deep Tonga', but I meant Deep Toga)
was subject to the problem, but I think I said also that other of the
chess engines were too - and, certainly, Texel is too.
I know that previously Deep Toga worked. I don't know about Texel; for,
I hadn't tried Texel until I started having problems.

This issue has served me to find an error but without a relation to the problem exposed, this error is fixed in my local code. Error = when MultiPV is active (in this case it is activated when option Set strength is other than best move, Intermediate in this case), then if engine like texel has an UCI_AnalyseMode option, it must be set to true to work properly. Texel with fixed depth 3 without using a book, in all cases move Nf3. When the error was fixed in the public release, in this particular case (where Set strength=Intermediate ) then the result will be other than Nf3, because the GUI select other moves of the list of moves presented (MultiPV) by the engine, but in this list Nf3 will be the bestmove again (because depth 3). |
In the case of Toga, with depth = 3 and Set strength=Intermediate:
With Set strength=Intermediate, it is better to select a fixed time than a fixed depth, because the limitation of power of the engine is done by the GUI. The engine select a list of moves with evaluations, the GUI select a move that has an eval less than bestmove. |
If I might add to this closed report . . The following
is, surely, much more complicated that it needs to be. Surely, users should not have to know this. Rather, they should be able to get some randomization - or perhaps, the lack of it, if they wish - just by pressing a few buttons. They should not have to know how the internals work. EDIT: Also, I just do not understand your instructions. All in all, I think that a change here would greatly improve LucasChess. EDIT: especially since, when Windows 10 Dark mode is enabled, the relevant labels are near-invisible: |
. . even when I have set the opening to 'undetermined'. The computer always opens with nf3 or, as black against e3, always plays Nf6. The problem occurs with the Deep Tonga engine and one other engine that I tried.
