What is Mittens’ ACTUAL Chess Rating?

Mittens is a chess bot recently released by Chess.com. It’s extremely strong and so far, only one human has managed to draw with it – GM Hikaru Nakamura. However, the website shows Mittens’ rating as 1, which we obviously know is untrue, seeing as it is the strongest bot on Chess.com – it can even draw with the “Maximum” bot!

In this video, I run a mock “tournament” featuring Mittens and some various chess engines, weakened to fit a certain ELO in order to determine its rating. I also explain how Mittens actually works and which engine it runs!

Engines:
Stockfish 15.1 running on AVX2, depth 20, i7-11370H @ 4.2 GHz
Komodo 13.02 running on depth 20, i7-11370H @ 4.2 GHz
Leela Chess Zero 0.29.0 running on CUDA, depth 8-10, RTX 3050 Ti

0:00 – Intro
0:08 – Mittens (?) vs. Komodo 13.02 (3388)
2:43 – Stockfish 2500 (2500) vs. Mittens (?)
4:31 – Stockfish 2700 (2700) vs. Mittens (?)
6:24 – What is Mittens’ rating?
6:32 – How does the bot work?
7:35 – Thanks for watching!
