I wonder what technique Lasker used to work it all out?
Thanks for the post.

The Lasker - Reichhelm position is not, as far as I know, the result of a game between them, but a common composition by them that has led to the theory of corresponding squares, not an application of it. I can only think that gifted contemporary players, aware of this theory, would be able to find the solution over the board. I can assure you, I am not one of them 🙁
