1. d4 {Notes by Nimzowitsch} d5 2. Nf3 Nf6 3. c4 e6 4. e3 c5
5. Bd3 Nc6 6. O-O dxc4 7. Bxc4 cxd4 8. exd4 Be7 9. Nc3 O-O
10. Be3 {10 d5 would be bad because of ...Na5 11 b3 Bb4; nor
would 10 Bg5 be good 10...b6, etc.} b6 {10...a6 and ...b5
would unneccessarily weaken the point c5.} 11. Qe2 Bb7
12. Rfd1 Nb4 13. Ne5 Rc8 14. Rac1 Nbd5 15. Nb5 {A
strategically noteworthy conception. White says to himself: in
the center I am strong, therefore a strategical diversion is
justified; moreover, I have no particular wish after say 15
Ba6 or Bd3 to be saddled with hanging Pawns. The right move
was, nevertheless, Ba6. For example 15 Ba6 Nxc3 16bxc3 Qc7 17
Bxb7 Qxb7 18 c4 with eventually a4-a5.} a6 16. Na7 {!} Ra8 {If
...Rc7 then Bxa6.} 17. Nac6 Qd6 18. Nxe7+ Qxe7 19. Bd3 {!}
Nxe3 {There was no occasion for this. Other lines of play to
be considered were (i) 19...a5 and ...Rfc8 (ii) 19...Rfd8
followed by ...Ktd7-f8} 20. fxe3 b5 {Weakens the point
c5. After 20...a5 (instead of the text move) and ...Rfc8,
there would not be much wrong with him.} 21. Rc5 {By occupying
this outpost station White gets play in the c-file.} Rfc8
22. Rdc1 g6 23. a3 {What now follows could serve as a textbook
example for play in an open file. The slowness with which
White step by step gains in terrain is also of significance
from the point of view of position play.} Ne8 24. b4 Nd6 {If
...Qg5 then Nxf7.} 25. Qf2 {!} f5 {In order to relieve the
f-Pawn and to make ...Qg5 possible.} 26. Qf4 Ne8 {Black can
undertake nothing.} 27. Be2 {!} Nd6 28. Bf3 {Breaks down the
opposition in the c-file.} Rxc5 29. dxc5 Ne8 {If 29...Ne4 then
30 c6 g5 31 cxb7 Rf8 32.Rc8 and wins.} 30. Rd1 Nf6 31. c6 {The
c-Pawn, the fruit of the operations on the c-file, now brings
the decision.} Bc8 32. c7 Ra7 33. Rd8+ Kg7 34. Rxc8 Rxc7
35. Nxg6 1-0
