Chess Traps: Noah's Ark Trap

The Noah's Ark Trap is a chess opening trap in the Ruy Lopez. The name is actually used to describe a family of traps in the Ruy Lopez in which a white bishop is trapped on the b3-square by black pawns.

The origin of the name is uncertain. The shape of the black pawns on a6, b5, and c4 may resemble an ark, or the name may suggest that the trap is "as old as Noah's Ark".

Even chess masters have occasionally fallen victim to this trap. An example is a game between Endre Steiner and José Capablanca at the Budapest tournament in 1929.
