Tarrasch Trap refers to two different chess opening traps in the Ruy Lopez that are named for Siegbert Tarrasch.
Unlike many variations that appear only in analysis, Tarrasch actually sprung his traps against masters in tournament games.
Two masters actually fell for this trap against Tarrasch: Johannes Zukertort at Frankfurt in 1887 and Isidor Gunsberg at Manchester in 1890.
Nxe6 The second Tarrasch Trap, sometimes referred to as the Dresden Trap, occurs in the Steinitz Variation.
Tarrasch published analysis of this trap in 1891, but 18 months later Georg Marco fell into it in Tarrasch versus Marco, Dresden 1892.
[1] Tarrasch spent just five minutes thinking during the entire game.
