poorthylacine: TO FRED LENNOX:
Your comparison seems very interesting and convincing about he styles of these two masters;
but at opposite, the difference is enormous when you include the personality: the weak point of von Bardeleben was his dramatic psychological fragility; in the Hastings tournament for instance he could not "digest" his defeat of Steinitz, the quality of his playing after their game declined much;
as long I know well, von Bardeleben later in his life became even insane at last; whereas Botvinnnik was like a man made of iron, a hard woker in openings preparation but too a player who could resist the most terrible pressure and stress in a dangerous situation, and fought always bitter on without sign of discouragement: his matches against Bronstein and Tahl are showing that; maybe the only exception was his match against Petrossian, when he began to feel really helpless facing such a kind of opponent... But his defense against Fischer in 1962 was so tough and bitter that even Fischer had to renounce to victory, unlike when he was facing Tahl one year before at Bled.
That's why personally I would compare Botvinnik rather with Tarrasch, but maybe I am wrong, of course...
