Why do poeple give other people jig-saws?
Also some good players including GM Jacob Aagaard have thrown
more light on 23...Qf3 in this position from the previous blog.
It appears in a Fred Reinfeld book (with the wrong solution) and the
above postion then appears as a test position in one of Jacob's books
after he had spotted the 23...Qf3 defence.
Some of you have the Fred book (I don't).
