And to make a better appraisal of the critical nature of this encounter, take a look at what he wrote about his opponent: 'Hardly had the direct attacking style given way to the positional, when Tarrasch appeared with his advocacy of the "new principles" of play. If these principles are followed in the games of Tarrasch himself, it becomes clear that in them there is no spirit of attack. Slowly, terribly slowly, almost stealthily, the chess forces move into play. Their motto is to avoid, as far as possible, an open battle and merely to besiege the opponent, blockade, and wait until his vital resources are exhausted, until his "air and water" run out, and then slowly crush him. For a long time this Tarrasch method has been extremely successful. His opponents either lost patience and bled to death in untimely sallies, or remained passive and were subjected to an absolute squeeze.'} d5 3. exd5 e4 {Falkbeer's classical counter-gambit – as played long before by Morphy!} 4. d3 {[#]} ({This would appear to be more promising than the alternative variation} 4.
