Thanks, Pavel and Yess! As I suspected, DS12 shows its real power
in longer games. In blitz games Stockfishes win almost all the time
against DS12x64 and DS11x64.

Best,

PS: Stockfish 16s DC & 162s DC should work on XP.
Perhaps you need installing some compiler distrib. files?

[DomLeste]

Pavel you need Microsoft Visual C++ 2008 SP1 Redistributable Package (x64) installed on your PC to make Dann Corbit Stockfish 1.6s compile work or else you get a error installing the engine.

I suspect that this is simply wrong

Stockfish does not win almost all the time in 40/4 against Shredder
and I do not see improvement of shredder relative to stockfish based on CEGT rating list



CEGT 40/4

for comparison
one result from CEGT 40/20

http://www.husvankempen.de/nunn/40_40%2 ... ons/4.html

Stockfish 1.6 x64 4CPU-Deep Shredder 12 x64 4CPU - 3066 69 + 28 = 32 - 9 63.8 %

I guess that stockfish was lucky in the match that it scored 63.8% but my point is that stockfish seems to score usually similiar results against shredder regardless of the time control(maybe shredder is bad in blitz with no increasement but if this is the case it is only time managament problem and there is no significant difference between 40/4 and 40/20).

[d] 2r3r1/1p1qb2k/p5pp/2n1Bp2/2RP3P/1P2PNQ1/5P1K/3R4 w - -

Ng5+!

very nice.

[BBauer]

Yes indeed very nice.

Stockfish found Ng5+ in 17 sec with a score of +68

Spark did not find it within 5 min.
Bright finds Ng5+ after 2 sec and holds it at least up to depth 18, but the score is after 6 min still 0.
kind regards

Thanks for the explanation and examples, Uri.
In my small blitz sample, this result is around 70% for S.:
