Re: What to do about this?

Hi Lyudmil :-), Given the material signature alone (Queen against rook, bishop with connected passers on both side) it should be winning for the queen side in most cases, i believe. But here it is not so an easy win as stockfish seems to believe. A passer with a protected rook behind it is very dang...

Re: What to do about this?

Sorry, not even close to a win for black. E.g 49.Qa6!(Stockfish) Rd5 50.Qd3 and the black passer is hemmed currently, whereas the white passers are not. White should have the better chances, in my opinion But still a highly complex, tactical endgame, where even current engines may fail repeatedly. Y...

Re: Positional quiesence

Hi Uri, in this position white has trumps as well: a strong bishop on c4, connected to a pawn wedge gives him currently some space advantage on the king side. The highly sophisticated pawn code of stockfish might take that into account too. But if you think stockfish could be improved here, i am sur...

Re: Core Port Saturation

Thank you for your hints.

I have one question: What happens if i call a function indirectly using a pointer, as it happens often when virtual methods are in play. Is there some sort of penalty, and how big is it?

Re: Debugging for lazy chess programmers

Hi Henrik, i have precollected the following urls about testing tools. They are looking promising but admittedly i have tried none of them so far: http://ccadar.github.io/klee/ http://research.microsoft.com/en-us/projects/pex/ http://code.google.com/p/crest/ Regression testing is relative cheap. You...

Re: King opposition

Hi Lucas, to introduce myself: i am a C++ programmer and a FM, but not a chess programmer. Now to your question: You messed it up somewhat. Cases 1/ and 3/ are direct and diagonal opposition, this is correct. But case 2/ is not opposition in any sense of it. Instead kings on d4 and d8 would be a cor...
