Nimzovich-Tarrasch, St. Petersburg 1914



Perhaps the long and bitter rivalry between Nimzovich and Tarrasch -- the former never missed an opportunity to vilify what he called "the Pseudo-Classical School" -- stemmed from this early game, in which Tarrasch gioves another example of the double-Bishop sacrifice. (See also Lasker-Bauer.)

St. Petersburg, 1914

QUEEN'S GAMBIT DECLINED


1. d4 d5 2. Nf3 c5 3. c4 e6 4. e3 Nf6 5. Bd3 Nc6 6. 0-0 Bd6 7. b3 0-0 8. Bb2 b6 9. Nbd2 Bb7 10. Rc1 Qe7 11. cxd5 exd5 12. Nh4


Provoking a weakness in the Black King's field, but the cost -- loss of time, opening of thje e-file -- is too high.

12. … g6 13. Nhf3 Rad8 14. dxc5

Opening the a1-h8 diagonal and hoping to exploit the static weakness of the "hanging pawns," but Tarrasch demonstrates their dynamic strength first.
