Sweet Mobility

In chess, more mobile pieces most often ensure victory. This happens when almost all pieces are developed and not restricted to cramped positions. This theory is illustrated in the following game.

Sopron, 1934
Queen's Gambit Declined

1. d4, Nf6
2. Nf3, e6
3. c4, Bb4+
4. Nd2, Ne4
5. e3, Nxd2
6. Bxd2, Bxd2
7. Qxd2, d5
8. Rc1, c6
9. Bd3, Nd7
10. 0-0, 0-0

At this point, both sides have been striving to relieve off cramped positions. White, however, has a much more free game.

11. e4! ....

White decides to open up more files to expand the control of his pieces.

11. .... dxe4
12. Bxe4, Nf6
13. Bb1, b6
14. Qf4, Bb7
15. Ne5, Qc7?

Black should have opened his Bishop's diagonal by the freeing move 15.....c5.

16. Rc3!, Nh5

17. Bxh7+!!, Kxh7

Effort by Black to turn down the Bishop would prove futile, as in 17.... Kh8, 18. Ng6+ wins the Black Queen.

18. Rh3, Kg8

A pretty situation arises after 18.....g6, 19. Nxg6 Qxf4, 20. Nxf4 in which case Black recovers his lost piece (Bishop) plus two extra pawns.

19. Rxh5, f6
20. Rh8, Resigns

Black loses the Queen after 20.....Kxh8, 21. Ng6+.

A wonderful game.
