Black has lost a move by not playing 25. ... Q to Q 2, for now he cannot
move his Queen away from the protection of the Knight, and the Knight {360}
he cannot move, because his K B P would then remain _en prise_. If he moved
26 ... K to Kt 2, defending Kt and P, White would win his Queen by playing
either Kt to B 5: ch., &c., as pointed out after Black's 23rd move; he is
consequently forced to move as in the text.
