Heimdall 1.1.1 wins Lucas Amateur Engines, 22.10.2024
https://chessengines.blogspot.com/2024/ ... gines.html

Lucas Chess (GUI) program and another amateur chess engine tournament. This time there were 10 of them, but we did a little experiment. Tcheran 4.0 played twice, which meant that he would play himself in the tournament. And he even won against himself (we are posting the game).
Stay tuned for more tests and results on our website.

Chess Engines Diary Rating Cup 10/2024 - quarterfinal: Stockfish 17 - Alexandria-7.0.0
https://chessengines.blogspot.com/2024/ ... 24_23.html

The first quarterfinal match of the Chess Engines Diary Rating Cup 10/2024 has ended. The Stockfish 17 engine won, but it was a minimal victory. In addition, as you will see in the game, it was a "technical victory" because the Alexandria-7.0.0 engine lost on time after just a few moves. It was most likely some bug at the engine-GUI interface.
The next matches are ongoing, the results will be on our website soon.
