Re: The Red Jewel 4CPU

Congrats to Rubi, impressive performance! Thank you Graham for organizing this! It was quite the rollercoaster for Winter, finishing really strong after a fairly abysmal first half of the event. I had a lot of fun following the event and chatting with the others.

Re: Chess programming C++

Definitely take a look at Andrew Grant's Ethereal. It is written in C, not C++, but the code is fairly straightforward and it is some of the cleanest and most well commented code I am aware of. Stockfish also has a lot of good comments and is in C++, but I find it a bit more difficult to follow as i...

Re: THE SSDF RATING LIST 2019-02-28

Money is always an issue with computer testing !! They don't need to be £500 RTX, you can go lower than that. The problem with going lower is that the other engines will be using superior hardware, which does not make it fair to test LCZero or other NN engines against Stockfish or Komodo, [...] I s...

Re: CCRL 40/40, 40/4 and FRC lists updated (23rd February 2019)

For the most part, I believe CCRL currently uses actual time controls closer to 40/20 rather than 40/40 due to the huge advancements made in CPU hardware. A modern quad core at 40/20 would be comparable to a 1050 at 40/20 because even though both pieces of hardware are much newer than the Athlon 46...

Re: CCRL 40/40, 40/4 and FRC lists updated (23rd February 2019)

Possible suggestion: The GTX 1050 has a low TDP doesn't use any additional PCI-E power connectors so it would probably be an easy upgrade for most of your existing systems (as long as they're not laptops). In the UK, it's priced very similarly to a modern quad core (the i3 8100 costs £113, the 1050...

Re: Leelafish with distilled network

I think it would be interesting to find out where the break even point is between Leelafish being stronger than both Leela and the auxiliary engine as a function of the auxiliary engine and the specific Leela. Ie for a fixed choice of Leela, what are the weakest engines that result in a Leelafish st...

Re: Leelafish with distilled network

Interesting, have you tried turning off the main engine and seeing how the auxilliary engine faires against Rybka?

Re: New engine releases 2019

Winter 0.5 has been released. I currently do not have access to a Windows computer, so the binaries are cross compiled from Linux and I am unable to test them on Windows at all. I switched to Lazy Ignorance SMP as I previously described on the technical section of this forum. On 4 cores this resulte...

Re: Top Engines without Piece-Square Tables?

I don't know how necessary they are. In Winter I use them for the positions of the King and Knight, but no other pieces. Mine are completely symmetric in terms of rotations and mirroring, which means mine probably encode less information than most PSTs.

Re: You lost to a cheater

I have experienced cheaters a few times on Lichess, but generally it is very rare and the people I suspect are usually caught rather quickly and the points being refunded. Probably the bigger issue for me is that I tend to let it tilt me a bit too much and I used to keep playing after such games. My...
