A sacrifice? No, it’s a lure

A fishing lure is designed to attract fish. Lures also are used in chess.

In this week’s position, black uses a lure to invite a mistake and then uses another lure to catch white’s king. With this hint in mind, please try to find how black mates white in three moves.

The position begins with black already tendering its first lure — black placed its queen in a position to be attacked by white’s bishop on f1.

White was not able to resist the lure of moving its knight from e2 to g3, which produced a discovered attack on black’s queen.

However, this gives black a mating attack. First black’s queen checks white from a4.

If white blocks the check with its queen, black’s queen takes the white queen with the support of its bishop and mates white.

White must thus move its king to c1. (The black rook on e8 prevents any flight to the “e” file.)

Now black employs its second lure: The black rook on e8 checks white from e1. White’s queen captures the rook, a move that lures the white queen away from its defense of c2.

Black’s queen then mates on c2 with the support of its bishop.

This week’s lesson is that a smart fish knows when to keep its mouth shut.
