Re: What was the last good Stockfish?

Hi Mike, sure, as it's GPL I added the sources in the .7z archive. It is just on the Rybka forum thread? It should compile as a regular stockfish. The changes are in types.h, evaluate.cpp and material.cpp. The original files are always renamed to evaluate_def.cpp etc. but the makefile will not read ...

Re: What was the last good Stockfish?

Were you able to download Bluefish anywhere? Is it available? Sure, I can make it available, Carl :) See Bluefish BMI2 (Beta) . No guarantees it has "style" though. It's just a half hour work or so, not a real Stockfish variant or fork yet. Eelco , Your compile is no good. Closes as soon as the exe...

Re: What was the last good Stockfish?

Well, yes, but sometimes even the Stockfish can be beaten by something that has all its evaluation parameters out of whack. And sometimes that thing can even win a match that it should not win by any logical statistics. Like it did here: Stockfish 2019-09-16 No Contempt - Bluefish 2019-09-25 No Cont...

Re: Is Black's compensation after 16. g3 really sufficient?

Hi guys, yes that is right, Shredder's way of indicating a "jump out of the search window" by a Fail Low or a Fail High. Other GUIs do that a bit differently sometimes. Stockfish for a while gave really long PVs even in case of a FL or FH but the moves are often very imprecise in such cases (*), eve...

Re: Stockfish 190826_dll_fix

The Stockfish binary sent in for TCEC was using a Windows dll ("dynamically linked library") that turned out to have a bug. The bug was somewhat noticed before by CoffeeOne in Stockfish team but it was not realized it was in the dll. Stockfish became unresponsive twice. If it had had three hangs it ...

Re: Is Black's compensation after 16. g3 really sufficient?

I let the search continue a little bit. For Stockfish I think the main line after Deep Junior's B sac is still a draw. White about 1½ pawn up but this advantage isn't growing anymore. Of course it is possible that Stockfish misses something. I would like to test the small change to Stock but I can't...

Re: Is Black's compensation after 16. g3 really sufficient?

Stockfish with a small change predicts 19.Nd1 and then 19...Nh2 even from move 11 after 2 minutes correctly predicting the lines after the Bishop sac as played in the match but deviating with 16.g3. So not so much 19.f5 from the diagram. rnbqr1k1/pp3ppp/2p2n2/3p4/3P4/P1NBP3/1PQ1NPPb/R1B2RK1 w - - 38...

That Mate in 5 again

Latest Stockfish Dev (2019-09-16, one thread, own compile, no tablebases). It's a monster :mrgreen: Oh well, at least it is getting there, currently failing high for the eleventh time and searching with a reduced depth of 67 plies. Ten hours and counting. rk6/p1r3p1/P3B1Kp/1p2B3/8/8/8/8 w - - Engine...
