Kookaburra 3.11 wins Elite Engines Test, 2025.11.25-27

Kookaburra 3.11 wins the Elite Chess Engines Tournament. Artemis 18.9 TR sl took second place, and PlentyChess 7.0.20 took third. It's worth noting the a PlentyChess engine's performance – it's getting stronger and stronger. I wonder if it will challenge Stockfish's dominance?
