The duolingo Oscar bot did something similar to me. It played 11 moves of book Yugoslav attack against my Sicilian Dragon, and then blundered horribly. I'm wondering if they programmed the bot to improve or to be very good at certain openings.

They might have. I tested the bot in a totally different opening. Besides blatantly giving away a bishop, it played at probably 90% accuracy:

Now I obviously did not play a great game. It was just down time playing bad bots and having fun, but this “200” ELO bot played 10 moves of opening theory in the Sicilian.
Back when I was rated 700, I knew maybe 3 moves of 2 variations of the Sicilian.
Who designed a 200 ELO to know 10 moves of theory?
If it’s just that I’m bad at chess, feel free to say that too lol. I will not have hurt feelings
