The first deep positional chess game

Wilhiem Steinitz, in his eariler years, was a very feared tactician. Also coming up with opening ideas- in ultra-complex openings like King's Gambit. His alertness and strength in combinations was too strong.

All of Steinitz's successes up to 1872 were achieved in the attack-at-all-costs "Romantic" style exemplified by Adolf Anderssen.

But in the Vienna 1873 chess tournament, Steinitz unveiled a new "positional" style of play which was to become the basis of modern chess.

Hardly was positional chess introduced at that time. However, Steinitz, in one game, defined this amazing magic of playing strategically.
