The featured game is from the Top Chess Engine Championship, Season 13, Division 4. Leela Chess Zero, equipped with two 1080 Ti’s, played as white against Chess22k which was run on 43 cores. The opening was an Open Sicilian, Classical where Leela opted for an atypical 11th move. This early atypical decision would set the stage for the remainder of this 79-move encounter. If one gives up their good bishop for a knight, there ought to be strong justification. What good reasons would the neural network have for doing so in this case?

I’m a self-taught National Master in chess out of Pennsylvania, USA who was introduced to the game by my father in 1988 at the age of 8. The purpose of this channel is to share my knowledge of chess to help others improve their game. I enjoy continuing to improve my understanding of this great game, albeit slowly.
