Steinitz was the first to show a method for the best utilization of the two Bishops. So far as is know, it was in the present game that he first applied his system. The theory of Steinitz applies to positions which are not close, but which, on the other hand, are not yet completely open in character. White still has support points at d4 and e5. The cornerstone of the Steinitz system is to deprive the opponent of such support points by means of pawn advances. The hostile pieces will thus be doomed to passivity, and the owner of the bishop pair should not find it difficult to set a decisive attack in motion. His contemporaries pointed out the weakness which these pawn advances must necessarily creat. Only through the games of Steinitz was it realized that such weaknesses are not so serious because two bishops can cover all the squares, being in this way much more useful for neutralizing weaknesses than two Knights or Knight and Bishop would be} 1... c5 2.
