First, the most strange thing is that Stockfish've lost Scorpio. Scorpio is an engine, that uses MCTS and neural-net training. Stockfish was playing on 70 contempt so it was weaker. Stockfish made a huge blunder on 32nd move. Then SF changed evaluation from +0,70 to -1,10. It is real power of NN and MCTS engines beating a/b engines.
Other thing is that The_Real_Greco, chess.com moderator and creator of CCCC declined my request to ann my chess engine to CCCC.
