Re: Building NN-powered engine

Another option might be to build some kind of adapter - an exe file which would load .py script and communicate with both GUI and the script - a man in the middle. That is exactly what python.exe is, right? An .exe file that takes a .py script and executes it. It 'communicates' with the script by l...

Re: On-line engine blitz tourney June

How would that be fairer than everyone using an opening book?

Re: "combo" type reset to default value in Arena GUI

No, that line is obligatory, if the engine uses significant memory space for tables. If you omit that line, the GUI will assume the engine doesn't support a hash table, and will not inform the engine of the amount of memory it can (maximally) use.

Re: "combo" type reset to default value in Arena GUI

Well, that is not really new. ChestUCI also has a non-standard option for settinh the hash size. (I believe it is called HashSize.) But you should not give it the same name as the standard option (i.e. 'Hash'). That would be non-compliant, and likely confuse GUIs. And of course it would then ignore ...

Re: about the value of fairy pieces

I would expect the Crab + Barc to have even more advantage over a Knight in the opening. As they have good forking power, there is still lots of stuff around to fork, and it is all worth more than they are. You cannot safely develop your minors if the opponent has Crabs & Barcs roaming around. I sup...

Re: "combo" type reset to default value in Arena GUI

What am I supposed to see here? Surely you don't expect the Hash option to appear in this dialog? On most GUIs it is a central setting, applied to all engines. That is why UCI defines it as a standard option, to make it possible for GUIs to do that.

Re: "combo" type reset to default value in Arena GUI

It doesn't matter what is more intuitive, better, or less clumsy. If the standard specifies you have to give the hash size as a string option in Roman numerals, you will have to use Roman numerals. Or you are non-compliant, and will experience that your 'better' solution will in fact not work at all...

Re: about the value of fairy pieces

I wonder about the case of Crab & Barc. Together they make a Knight. They are 4-target pieces, like Ferz and Wazir, but they are not as slow and hard-to-develop as the Wazir, and not color-bound like the Ferz. Like the Ferz, they have good forwardness. Perhaps 90-degree-rotated versions would even b...

Re: about the value of fairy pieces

Well, I am not sure. The value of a piece (or set of pieces) is basically the damage you can do with it until it expires. So it depends on the targets you aim to damage. Our intuition is Chess is highly shaped by the idea that these are Pawn chains. But orthodox Pawns move in such a way that Pawn ch...
