Black expected 21 Ne4(!), which he intended
to meet with 21 .. Rac8, banking on the trap 22
Qh8+? Ke7 23 Qxg7 ..Bd4 ! ! . However, 22 0-0!
(or 22 Ke2 !) is strong, and indeed a rather
clearer win than the move chosen, but both
lines are good if followed up accurately.
To Schroeder's chagrin, Capablanca sidestepped
the trap, although in a different way:21.Qh8+!?Ke722.Qxg7hxg523.Qxg5+Kd624.Ke2!?Rac825.Rc4Kc626.Rhc1Kb6Let us consider this position from the standpoint
of the principle of two weaknesses. We
are struck by the ridiculous bunch of black
pieces on the queenside, tied to the defence of
the bishop on c5. This entanglement may be
viewed as the first weakness. The game is decided
by executing a second threat - on the
kingside.27.h4!f528.Qg7!Re729.Qe5Rc630.Rxc51-0 Black resigns.1-0
