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?

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'

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...

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 ...

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...

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...

Highly unlikely of course, but that's the official line.

This has got to be the correct answer. I voted black win as well.
