‘WIESBADEN, Sept. 17 – The sixth game of my championship match with E.D. Bogoljubow resulted in a victory for the challenger, made the honors even again in the championship, and once more the cause of my losing is to be found in my choice of an unfortunate variation as the player of the black pieces.
This time, however, the defeat was not due to an unsound development of pieces as was the case in the fourth and fifth games, but because a tactical “joker” was overlooked in the course of working out a somewhat complicated variation.
On the 15th [sic] move, pawn to queen’s knight three, the player of the black pieces overlooked the reinforced counter-move employed in the chief variation which was played on this occasion – that is, after pawn to king’s four on 11th move, knight to king’s sixth cannot be played because of queen to queen’s three on the 12th move. After the retreat of knight to king’s two and the enforced exchange of queens which followed a few moves later, a position resulted which, in view of the existing general weakness of the entire queen’s wing, could not be defended against by accurate play.
Yet I have the impression that Bogoljubow’s play from then on, although well carried out, nevertheless lacked “absolute exactness” for on the 18th [sic] move it was possible for me, by playing rook to queen’s square and only then knight to bishop’s square, to make it difficult for him to find the path to win.
After this lapse, which is further indication that as yet I have not been able to get into my real stride in this match, Black had only a few harmless tactical sorties at his disposal, and finally he had to yield to the inevitable.
The following variation may be noted: 47th move, knight to knight’s 5, rook to knight’s 5, 48th, pawn to rook’s 5, knight to bishop’s four mate.
Thus, out of six games played, four have ended decisively – an unusually high percentage for a match of this importance and which may be explained on the ground that both players have selected risky variations when handling the black pieces. Perhaps the present pace will let up in the course of the next few games, but in any event, the match promises to become more exciting than was at first generally expected.’>
