From a recent online Arasan game: r1bq1r2/bp3pk1/2pp4/p6p/P1BPPP1N/6Bn/1P4pK/2RQR3 w - - 0 22 White played Nxg2 and won. But on longer analysis, it appears f5! and allowing Black to promote is even better. Stockfish and Houdini are very fast on this. But other engines have difficulty (Fritz 16 for e...

In the winter, when I run it like gangbusters, I get electric bills of $600 to $700 per month. I have a 6.6 KW solar system now. I only pay for net usage after subtracting the solar contribution. But billing is based on time of day, so I try to avoid running my multiple servers in the peak billing ...

I have noticed that besides the published solution Qe4, Qf5 is a mate also: [Event "?"] [Site "?"] [Date "????.??.??"] [Round "?"] [White "?"] [Black "?"] [Result "*"] [SetUp "1"] [FEN "8/pp3k2/2p1qp2/2P5/5P2/1R2p1rp/PP2R3/4K2Q b - - 0 1"] [PlyCount "37"] {[#]} 1... Qf5 {Stockfish 10 64 BMI2: 1)} 2....

It looks like the whole variation with 7. .. b5 is being avoided recently. A search for games in Correspondence DB for players >=2250 found 5 games 2017-2019 and all were White wins. OTB players are trying it more often and are more successful but it looks like if White follows the best line Black i...

It is just that it is VERY hard to find places that configure 3rd gen threadripper systems.

On top of that there seems to be a serious supply problem with a bunch of AMD chips, including the Ryzen 3000 series.

their price is high ... e.g., the upgrade to the 3970 from 3960 should be $600 to $ 800 max, not $1200... Yeah, it is very high. I am thinking about building a 32-core Threadripper system, but I'd probably use to replace my 2013-era Opteron system and reuse its big server case and some of its compo...

Carlsen is hardly the guy to fear for opening knowledge.

He is pretty well prepared and keeps innovating. See the article on the 7. Nd5 Sveshnikov in NIC Yearbook for example.

But I still think Kasparov takes the prize for relentless, deep opening preparation.
