Lesson
White to move. Main line: 1. Qb8+ Nxb8 2. Rd8#
1.Qb8+! forces the knight from d7 to b8. The queen disappears, but so does the last defender of d8.
2.Rd8# is the Opera mate: the rook checks along the back rank, the bishop on g5 protects d8, and Black’s own pieces remove every flight square.
Morphy’s finish is a model of development becoming tactics. Material no longer matters when every active piece participates and the defending army is still trapped at home.
