{ A match for the world title was not played for a long time. The first
contacts between Lasker and Capablanca ended in quarrels. A match between
Lasker and Rubinstein was abolished due to world war I. During the great war
Lasker and Tarrasch played a short, informal match.  Little happened in the
first part of the game. } 54. Bxg5 $2 { The good bishop disappears. } ( 54. Bf2 hxg4 55. fxg4 $1 Qh6 56. Nf1 Rh8 57. Ng1 Bf4 58. h4 { and White has a fortress. } ) 54... Nxg5 55.
