Irina Krush vs Pia Cramling · 2012 · move 21.

Which bishop move lines up with the pawn on e6 and queen on c8?

Krush’s 2012 world championship encounter with Cramling offers a clear example of a relative pin. A bishop points through the e6-pawn toward the queen on c8. When Black’s bishop leaves e7, White can take a rook with the queen because the pawn recapture exposes the queen behind it. The resulting ending keeps White’s rooks active.
