Re: Any compositions like this?

Certainly you are right and the OP deserves better. Other than the original posted here, only the 15 alternatives: 1Kr4k/3R4/1P1Q1P2/1P2BBR1/1P6/1P6/1PP3P1/2NN4 w - - pv Ka7; 2nn4/1pp3p1/1p6/1p6/1p2bbr1/1p1q1p2/1k1r4/2R4K b - - pv Ka2; 2nn4/1pp3p1/1p6/1p6/1p2bbr1/1p1q1p2/3r4/1kR4K b - - pv Ka2; 2nn...

Re: I did some magic bitboard "science" and mostly learned not to worry about it

OK, thanks, that makes perfect sense.
Compilers today can be incredibly efficient.
Long ago, they could eliminate tail recursion.
Now, they even improve algorithms (no, really).

Re: MadChess 3.0 Released

Typically, Stockfish of old would be about one megabyte. But now that everyone is pulling 20MB of dead weight NN nodes into the binary (we used to read data with I/O, but today people can't be bothered to browse to a file), it has ballooned into a blue whale. Well, I do have a 140 TB disk server, so...

Re: Hardest chess variant for human

Fourth dimensional Go, played on a tesseract. Hard to do in ordinary 3-space, but computers can always expand the inner dimension to enable one more. Go is not a "chess variant". Well, a springer is not a chess man. And an Archbishop does not move like any particular chess piece. It is a strategy g...

Re: MadChess 3.0 Released

On this page:
https://www.madchess.net/downloads/

I saw a link for source and a link for executables for each version.
There are binaries in the binaries zips.

I guess that there is a requirement that all new chess engines must now exceed 20MB.

When there is no wood, the fire goes out

Just a thought, when it comes to some recent tit-for-tat posts. Some trolling is irresistible, though. When I was little, I had a bozo the clown punching bag. It was full of air and there was a weight in the bottom. If you punched him in the noze, he went all the way over till he was flat on the gro...

Re: TCEC - recent komododragon verses stockfish games...

There were some very recent games on TCEC between Komododragon and Stockfish. I went to go download the games and I cannot find them. Does anyone know where they went? They looked very interesting to me. Look at the Games section. https://tcec-chess.com/#div=ram&game=1&season=20 Ghost post alert :)...
