The diagrammed position comes from a game between Alekhine and Capablanca. It was from the 1914 St Petersburg tournament and it is Black (Capablanca) to move. In The Art of Chess Combination, Eugene Znosko-Borovsky heaps praise on the game continuation 1... Nxg2 2.Kxg2 Qg4+ 3.Kf1 Qh3+ 4.Ke2 Rxe3+ 5.fxe3 Qxe3+ 6.Kd1 Qxe1+ and disparages the 'variation without a surprise' 1. ... Qg4 2.Qb7 d5 3.f3 Qe6 4.Bxf4 Rxe1+
As it turns out the second variation is actually stronger than the first, although Znosko-Borovsky missed a brilliant sting in the tail. After Rxe1+ he simply states that Black wins the exchange at the price of the menace to the d pawn. However, if after 5.Kf2 Black finds 5. ... Rh1!! then he wins the other rook as well!
I wonder if part of the reason why Znosko-Borovsky didn't look too deeply at the second continuation was that he simply decided that if Capablanca played it, then it must be best.
