Riddle: Is active defense always best?
A week ago we showed you a famous game, played between Siegbert Tarrasch and Akiba Rubinstein in 1911. It ended in a draw, and is given as a model example for an active defence in rook endings. However, that was not the clear conclusion to draw from the game, and we asked you whether you could find the mistakes in the game play strategy? Wolfram Schön provided a very deep answer.
