It doesn't look like there is a Linux build.

It's in the dev builds section, I think.

strong engine, beats houdini easily at blitz. i tested the new compile released today at 1 second per move 100 games no books or tablebases

stockfish_13081809_x64_modern = 9
-vs-
stockfish_13082819_x64_modern = 15
draws = 76

houdini 3 pro x64
809 won 9 games out of 100
819 won 15 games out of 100
76 games were draws

but the newest compiles (stockfish_13090211_x64 ) just get better. stockfish is the best :)

I don't get your statistics..
what's 809 won 9 games? out of 100?
and 819 won 15? out of 100?

stockfish_13081809_x64_modern is 809
stockfish_13082819_x64_modern is 819


stockfish_13081809_x64_modern = 9
means that the score was +9 =76 -15

stockfish_13082819_x64_modern = 15
means that the score was +15 =76 -9

You can figure these out because 100 games with 76 draws you only need one other number to figure the totals.
I think it would be better to just print the whole line, because obviously people can be confused by it.
By the way, it takes thousands of games when the engines are close to really know which one is better.
