Well, there is nothing I can do to prove to you that I did, as I can not travel into the past taking you with me. I know, I did win two or three games and drew approximately 25 out of approximately 500 training games. But I can not prove it. You have to believe or not.

I believe you. I just suspect stockfish was misconfigured, it wasn’t playing at its highest skill level or something similar was going on. That seems more likely. (I’d love to know for sure though).

An extraordinary claim without any proof. Surely you believe the moon to be made of cheese, since we can‘t travel there to verify it‘s not?

Yeah his claim is quite absurd really. If it was a weaker stockfish (bad hardware, older version etc.) then maybe. Modern stockfish pretty much crushes any and everyone. A draw alone would be extremely impressive, and maybe doable with enough luck from a top player. But even that is very far fetched nowadays. Let alone actually winning.
