The theory
Watch the method: press play to see the winning idea run, or step through it move by move.
See what happens if the rook leaves that chain with Rb5. Qe8+ checks your king and hits the rook at the same time: Kd4 Qxb5.
The queen outweighs rook and bishop, but a fortress erases the gap: the bishop's reach and the rook together shield the king, and the queen has no breakthrough.
The queen's two tries, and the parries. (1) Win the bishop by attacking it while it is undefended: parry by keeping the bishop guarded by your king and on the diagonal that denies the queen its checking squares. (2) Check the king into the open: parry by keeping the king behind the bishop's diagonal and the rook, so checks meet an interposition.
The losing break. A loose bishop or rook falls to a queen double attack, and a king dragged onto an open file or diagonal is forked. Keep the bishop guarded by the king, the rook out of reach, and the king covered.
In this drill you defend with rook and bishop. Keep the wall intact and dodge the forks: the queen cannot crack a sound fortress.
