Re: Game time in fraction of minutes in Arena.

Choose blitz mode. Set initial time to 30 seconds and increment to 0 milliseconds.

Re: Ridiculous QSearch Depth

Is qsearch normally included in seldepth? In my engine I check for maximum depth (or ply rather) at the horizon.

Re: Windows 10 slowdown after anniversary update

Is it your engine only that is slower?

Have you tried other engines/benchmarks? Have you tried different versions of your own engine compiled before and after the Windows update? Or maybe a GCC update? What does the performance monitor show?

Re: How to use Arena book?

You also have to tell each engine to actually use the book.

Engines->Manage->Details

Under the Books tab, check 'Use Arena main book with this engine'

Re: Abbess 2016

1. Yes. 2. Yes, but I have the C++ runtime libraries installed. 3. I've only tested it in one very fast game (against my own engine, Wraith). Pretty wild stuff: [pgn] [Event "Computer chess game"] [Site "KELLY"] [Date "2016.12.19"] [Round "?"] [White "Wraith 0.91a"] [Black "Abbess2016"] [Result "1-0...

Re: Code review , and what is the next step ?

But if you look at how he does iterative deepening, the "d-1" call is inside a loop over the moves. So we are not talking about q_search of the root: Yes, you're right. I missed that outer move loop. Probably because I don't to it that way myself. Edit: Too much code to go through, and maybe there'...

///isn't it wrong to descend directly to qsearch at the first loop : d-1=0 Yes, it is. Well, maybe not technically wrong, but you're constantly searching 1 ply less than intended. auto Score = -AlphaBeta(-beta, -alpha, d - 1, true); Here's the actual line. It's like you want to search to a ...

Re: What for a bullshit clone discussion!

Not knowing any Spanish (or Portuguese?), I put the phrase into google translate. It gave "Fool of the ass came out the clown" Google also said Did you mean: Tonto del culo salió el payaso (with an accent on the o of salió, incase you do not see this in your browser) That translated as "Silly ass c...

Re: You make the call..

I think rule 6.9 must be applied here. It's commonly agreed that 2 knights alone cannot force a mate. Hence the result must be draw. Even KNNK is not a draw under FIDE rules. Although it cannot be forced, two knights can deliver mate. And, like Graham said, it can sometimes be forced with other mat...
