Why does Martin play so well? how???

martin with elo 250 beat me when i had standard elo 800 with martin's accuracy of 91.5 and has a rating of 1250 elo 💀 I wonder if this match was because I played too noob or did martin use stockfish to fight me 🤔?

I doubt Martin used stalefish as its a bot itself, and one tuned to make mistakes. I just didn't make as many mistakes as it should have at 90% accuracy.
