Stop using stockfish.

You lost two games today that went to the middle game. In one during the middle game it oscillated between mate in 1 for either side every move for like 10 moves, it was actually pretty funny. In the other one your opponent hung a queen in the middle game but you didn't take it and eventually gave up all your pieces. Neither of those cases is even remotely suspicious or would ever be possible against the fish.

Ah I see. Thank you for giving me an explanation, although I'm a 600 ish, a beginner, i probably couldn't see that. I've reviewed my games and I couldn't see where my opponent hung a queen. Could you show me?

Some player are better in middle game, endgame or the opening. Playing better in one of these doesn't mean the person is using stockfish
