PlentyChess 6.0.18 wins New Amateur Engines Test, 2025.09.18-23


PlentyChess 6.0.18 won the amateur chess engine tournament on a 12-year-old computer. Caissa 1.23 came in second, and Boot 7.4 came in third. Incidentally, we should add that for the first time, the tournament was run on Windows 11, which we managed to install despite hardware limitations. And the "rugged old" laptop works.
