The Rubinstein Trap: the pawn on d5 isn't protected, because the queen can be trapped

The pawn on d5 looks protected by the pawn on c6. But if Black recaptures on d5, White's bishop jumps to c7, and Black's queen has nowhere to go. One of the best players of his time fell into the trap twice.

The trap

The trap arises in the Queen's Gambit Declined, in the Orthodox Defense. White has exchanged on d5, and Black's pawn there is supported by the pawn on c6.

Black has played 11…Ne4 and wants to trade pieces. After 12.Bf4 Black protects the knight with 12…f5.

Why it's easy to fall for

12…f5 is a logical move. The pawn protects the knight on e4, and the pawn on d5 still looks protected.

But Black's queen on d8 has almost no squares. The rook is on e8, the bishop on e7, the knight on d7 and the other bishop on c8. After 13.Nxd5! Black can't recapture, because 13…cxd5 is met by 14.Bc7, and the queen is trapped.

What Black should have played

Protect the knight with a piece instead: 12…Ndf6. Then d5 really is protected, and White is only slightly better.

If White has already taken on d5, Black shouldn't recapture. The pawn is lost, but the queen is still there.

12… Ndf6

Right. The knight protects both e4 and d5. White is slightly better, no more.

How it ends

If Black recaptures on d5, Black loses the queen for a bishop. If Black doesn't, White is still clearly better, with at least an extra pawn.

The history

The trap is named after Akiba Rubinstein, one of the strongest players of the early 20th century. He fell into it twice with Black: against Max Euwe in Bad Kissingen in 1928, that time after 12…Nh5, and against Alexander Alekhine in San Remo in 1930, after 12…f5. Both times 13.Nxd5 came. Rubinstein didn't recapture on d5, but the pawn was lost, and he lost both games.

He wasn't the first. The chess historian Edward Winter has found an even older game with the same idea, Burn–Wolf in Ostend in 1905.

Frequently asked questions

What is the Rubinstein Trap?

A trap in the Queen's Gambit Declined. White takes on d5 with the knight, and if Black recaptures, Bc7 traps the queen on d8. Akiba Rubinstein fell into it twice, in 1928 and 1930.

Why can't Black recapture on d5?

Because the queen on d8 has no squares. After Bc7 it is attacked, and the rook, the bishops and the knight are in its way.
