The Rubinstein Trap is a chess opening trap in the Queen’s Gambit Declined, Orthodox Defense. This subtle trap at the very least wins an important central pawn, but also can trap the black queen if Black is greedy.
Rubinstein trap is named after Akiba Rubinstein. Interestingly, it is not because Rubinstein was the player who invented the trap, but because he got trapped twice into it, in the games Max Euwe–Rubinstein, Bad Kissingen 1928, and Alexander Alekhine–Rubinstein, San Remo 1930.
