This strikes me as an excellent example of ignoring the opponent's threat, making the move you really want to play work. It also shows the acute feeling strong players have for the importance of piece activity relative to material.
As soon as I saw the move on the board, it made perfect sense. But my friend (who is also a master) and I hadn't predicted it while quickly playing through the game solitaire chess. I think this is a perfect example of a strong positional forcing move.
In the Petrosian-Botvinnik game I mentioned last time, I really enjoyed some of Petrosian's aggressive moves that a cursory examination of forcing moves (checks, captures, and threats) wouldn't necessarily catch.
I wanted to share news of a very interesting new book: "Modern Chess: From Steinitz to the 21st Century" by International Master Craig Pritchett. This Thinkers Publishing title is exactly what it sounds like, and has something for chess enthusiasts of all levels: Some history, some culture, some famous games we ought to have seen but maybe haven't, some instruction.
I wanted to offer another position that could be profitably solved by both newer and club level young tournament players. I got the position from the new book, "Tata Steel Chess Tournament 2021", by Grandmaster Daniel Fernandez.
