{I had published, some months previously, an analysis of the
variation 11...d4, and I gave the text moves as an example of
a simple way for White to play against it in order to obtain
the better game. I left off at the above position, stating
that White had the better game. Chajes and a few other local
players studied the analysis, and came to the conclusion that
was wrong. They thought that Black had at least as good a game
as White; in fact, better. Therefore Chajes availed himself of
the first opportunity to prove his contention. I was ignorant
of all this at the time, and was consequently very much
surprised at his "falling" (as I thought) into my published
variation, and commented on it to one of the spectators, who
then enlightened me as to the true reason of his play. The
game, I hope, will show that my judgment was better than his,
as at no point of the proceedings was I in danger of obtaining
anything worse than a draw. The advantage of White rests
mainly on the strength of the pawn at e5, which largely
restricts the action of the Black pieces, while it gives
plenty of freedom for the maneuvering of the White forces.}

h6 {A bad move, which shows that Black did not properly
understand the position. He wants to prevent the pinning of
the Knight by Bg5 and does not realize that the posting of the
White Bishop at a3 (after Nb3) is much more important. He
should now castle when White's best move would probably be
19.Be3} 19.Nb3 Bb6 20.Ba3 h5 {He now must attempt to bring his

maneuvering of Black's pieces; therefore in desperation he
advances the f-pawn to get rid of White's e-pawn, and thus
have breathing space.} 28. exf6 Rxf6 29. Re1 Be6 {29... Re6
