Re: Stockfish 10 beta
Thank You!
Here is a little testposition from latest WCC game today:
Caruana,F - Carlsen,M 1/2-1/2, World Chess Championship 2018
[d]1r1q1rk1/1p2b2p/pN6/P1pP1bp1/5p2/2B2Q2/1P4PP/R4RK1 w - - 0 1
Analysis by Stockfish 191118 64 POPCNT:
23.Tad1 Ld6 24.Dh5 De8 25.Dxg5+ Dg6 26.Dxg6+ hxg6 27.Sc4 Tbd8 28.Sxd6 Txd6 29.Le5 Tdd8 30.Txf4 Tfe8 31.Lc3 Te4 32.Txe4 Lxe4 33.d6 Kf7 34.Te1 Lf5 35.Te7+ Kf8 36.Txb7 Txd6 37.Kf2 g5 38.Tc7 Td5 39.Ke3 Td3+ 40.Ke2 Td5 41.Kf2 Ke8 42.Kf3 Ld3 43.Ke3 Lf1 44.g3 Ld3 45.Ta7 Lf1 46.Tg7 Kf8 47.Tc7 Ke8 48.Kf3
+- (1.83 ++) Tiefe: 43/58 00:09:47 1622MN, tb=12193
Much better move here is 23.Rae1! with clear better chances to win. 23.Rad1 is good too, but not the best way. On my smartphone Stockfish 9 finds very quickly 23. Rae1! Why not Stockfish 10 beta too?

23. g4! is winning... (has a much higher score - probably analysed with backward, forward hash filling >+4)

Re: Stockfish 10 beta
Thank You!
Nevertheless, here Rae1 is better than Rad1, and Stockfish 9 (Smartphone version) finds. A diagram pictures (live from game with the Playchess app) can you see here on my homepage: https://en-chess.jimdofree.com/wcc2018/
Thanks anyway
Best wishes!

For those of us who plan on compiling our own, any tips / tricks / flag configurations to maximise speed? Using MinGW + GCC 8.1

Re: Stockfish 10 beta
Can someone explain me? I have set the contempt to 0. Now Stockfish 10 beta plays a little bit better.
It seems that contempt 24 is to much.

Re: Stockfish 10 beta
Contempt has value when you have an inferior opponent. Suppose, for instance, that you come out of an opening book and your opponent is a little bit ahead of you (perhaps a quarter of a pawn). If you have an equal opponent, and you can find nothing better, it is a good idea to strive for a draw.
But suppose that your opponent is much weaker than you are. Now it is probably not a good idea to strive for a draw because you will probably win the game if you play on and avoid a draw.
So if (for instance) you have contempt on during self-play, you will see absurd things like both sides being ahead at the same time, according to the evaluation.
Unfortunately, with the standard Stockfish, you cannot turn off all of the contempt, but only part of it.
So I modify Stockfish so that I can use it for analysis and get the right answer.
Now, there is clearly a real affect of having contempt when it comes to game play. So it is a good idea for a chess engine. But when analyzing, it is telling you a small lie, which is bad.
IMO-YMMV

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Stockfish 10 beta
Played 3 matches with the latest development version against SF9
Impressive!
Code: Select all
Match games Time Perc ELO
sf10 - sf9 10,000 15+0.1 60.2% +72
sf10 - sf9 10,000 30+0.2 59.9% +69
sf10 - sf9 10,000 60+0.4 59.5% +67
90% of coding is debugging, the other 10% is writing bugs.
