Re: Sapeli 1.0 - New chess engine

The UCI spec says that "isready" must also be answered during search - but only "stop" is evaluated. This might make GUIs kill Sapeli because they may assume it is hanging.

Re: Dylan Sharp Vs. Harvey Williamson (G4)

Good game, thanks to both players! Some questions: 1) Early on, White sacrificed a central pawn. On move 10, I count only two tempi in compensation, and with the quiet 10th move, that goes even down to one tempo. Usually, a pawn is considered about three tempi in the opening. Does that make the pawn...

You have no clue, who is the troll here?
A game is a game, and I want to see it going. Also, it's bad chess etiquette to constantly chime in like that. If White loses, the time for "told you so" will be after the game.

Re: Dylan Sharp Vs. Harvey Williamson (G4)

First, thanks for the game, it's really exciting. And double thanks for making it open again.

Can the "but but but my Stockfish says bla bla bla" fraction please shut up lest the players decide to continue the game via PM again?

Re: Breaking news - Chess and the Blind

How do you do the translations? Is there some sort of text file with predefined strings for each language?

Re: Banksia GUI released

Wow, thanks for the info. Can you tell me the name (and download links if you have) of those DLL? It's api-ms-win-core-winrt-l1-1-0.dll and api-ms-win-core-winrt-string-l1-1-0.dll . Either you extract that from a Win10 system that you have around, or you could also get them from https://wikidll.com...

Re: Banksia GUI released

Actually, it does run under Win7-64 - just two additional MS DLLs required. Although I don't quite see the point of making it Win10 and MacOS only for now. My CT800 UCI engine seems to work nicely. Some things I noticed when playing around: 1) Why do I have to enter the engine name manually? That sh...

So if I need to now which one is best (after the TT one), I need to score them all (at least captures ...)
You could use MVV/LVA at this stage because that's cheap, pick the highest one of these and see whether you get a cut-off. If not, you can score and sort the remaining ones via SEE.

Re: Minic raw speed

Minic is sorting all moves as soon as TT move is not a beta cut-off You could benchmark how often your first move cuts off if it isn't a TT hit, this will probably be something like 50-70%. Means, in all those cases, sorting the full move list is unnecessary because you're only going to use the top...

Re: Limiting nodes to reduce engine strength

Not a fan of a depth limit, since they can occasionally be quite "coarse" in terms of time. And also unrealistic because humans also calculate deeper if there are fewer moves to consider. I have a pretty decent NPS idea in the works. I have normalized on 2800 Elo == 6M nodes per second (on my MacBo...
