It was really remarkable to see Komodo and Stockfish, playing without book, decide to go into the most complicated opening in chess, the Botvinnik variation, and a particularly sharp subline at that, one that I have played myself in tournament chess. Players capable of duplicating this many moves of critical opening theory without any book knowledge are surely worthy of the 3400+ ratings they get in various lists. Even though the line is probably a bit favorable for White, Stockfish gets credit for choosing this somewhat unclear line over a normal defense where Black is just slightly but obviously worse.

It seems to me that stockfish did a mistake at move 20

I wonder why not 20...Kg8

A Lot of positionally forced moves(difference between best and second best more than 1/3 pawn) and tactically forced moves(difference between best and second best is more than a pawn)

some analysis of moves 6-10(more in the next post)

It was really remarkable to see Komodo and Stockfish, playing without book, decide to go into the most complicated opening in chess, the Botvinnik variation, and a particularly sharp subline at that, one that I have played myself in tournament chess. Players capable of duplicating this many moves of critical opening theory without any book knowledge are surely worthy of the 3400+ ratings they get in various lists. Even though the line is probably a bit favorable for White, Stockfish gets credit for choosing this somewhat unclear line over a normal defense where Black is just slightly but obviously worse.

Well like you said, Komodo is your son, playing like you with more power

I stop the analysis and it seems that fxg6 is forced
