Re: New engine releases & news 2021
Dumb 1.7 https://github.com/abulmo/Dumb/ Is anyone able to make a Windows compile for this ? The link above only has Linux. I'd be running it on an AMD FX8350, which has popcnt and SSE4.2 and SSE4a support, but not AVX2 or BMI2. Thanks. Sorry, I forgot to upload the windows binaries. You can now fi...

Dumb 1.6 : https://github.com/abulmo/Dumb/releases/tag/1.6 The zip file for the Windows compiles contains two files, supposedly 32 and 64 bits, but the compiles are identical 64 bit compiles. Sorry, I did not know there was still some 32-bits Windows in the wild :) . I have uploaded a new zip file ...

Re: New engine releases 2020
Have fun with it. Hello! For your information, I cannot use the Linux binary of Dumb 1.6. [roland@localhost 16]$ ./dumb-1.6 ./dumb-1.6: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by ./dumb-1.6) [roland@localhost 16]$ It seems that I have to compile the source. I search how I can ins...

Re: Are Aspiration Windows Worthless?
I just run some experimentations that strongly disagree with your findings. The aspiration windows algorithm is definitely worth on my engines. I got the following results, with self play using SPRT stop condition: - Dumb : +54.2 +/- 7.3 Elo (834 games) - Amoeba : +131.6 +/- 12.2 Elo (260 games) Be...

Re: Delimiter development diary
D programmers don't have enough chess engines to work from. I figured having a simple base will make it easier for others to create their engines. I agree there are not many chess engines in D, but I have written two of them: https://github.com/abulmo/amoeba https://github.com/abulmo/Dumb Dumb is a...

Re: what is the longest tablebase mate with special properties?
r6R/k7/p2K4/P7/8/8/7P/8 w - - 0 1 This is mate in 9, with a single path: 1.Rxa8+ Kxa8 2. Kc7 Ka7 3. h3! Ka8 4. h4 Ka7 5. h5 Ka8 6. h6 Ka7 7. h7 Ka8 8. h8=Q+ Ka7 9. Qb8# (1... Kb7 allows mate in 6, so the complexity is only 1.) Strictly, though, the tablebases don't show at the start that 1.Rxa8+ is...
