Qf2 {White has already begun an attack on one flank, but this move gives notice that he intends to keep Black busy on the other flank as well} 17... Nxe5 18. Nxe5 Nd7 19. Nf3 $1 {In dealing with the subject of the initiative we established the principle that the side with an advantage in space should avoid exchanges. The fact that we see this principle here during the process of maneuvering is not suprising, for alternative maneuvers are, as we know, a form of the intiative} 19... Rdc8 (19... dxc4 20. Bxc4 Bf7 21. -- Nf6 (21... Nb6)) 20. c5 Nf6 21. a4 Ng4 22. Qe1 Nh6 23. h3 Nf7 24. g4 {White has the initiative on both sides of the board. The art of maneuvering now is to use the greater speed with which he can switch his forces from one flank to the other to stretch Black's cramped defenders to the breaking point} 24... Bd7 25. Rc2 Kh8 26. Rg2 Rg8 27. g5 { White could no longer leave his pawn on the fourth rank as Black threatened ... Pg5} (27. gxf5 $2 {fine for Black}) 27... Qd8 28. h4 Kg7 (28... h5 29. gxh6 Nxh6 {The g6 square would have been too weak}) 29. h5 {White has attained an ideal maneuvering position. At any favourable moment he can open a file for his Rooks on whichever flank he chooses} 29... Rh8 30. Rh2 Qc7 31. Qc3 Qd8 { Black is completely passive} 32. Kf2 Qc7 33. Rbh1 Rag8 34. Qa1 Rb8 35. Qa3 { Here and the next few moves Capablanca rather suprisingly rejects the thematic line Rh3, R1h2 and Qh1 trebling on theh-file} 35... Rbg8 36. b5 $1 axb5 (36... cxb5 37. h6+ $1 Kf8 38. c6+ $18) 37. h6+ {An extremely important moment, in which the actions on the two flanks seem to converge.} (37. axb5 gxh5 $1 38. Rxh5 Ra8 $132) 37... Kf8 38. axb5 Ke7 39. b6 {Now Black is completely encircled } 39... Qb8 40. Ra1 Rc8 41. Qb4 Rhd8 42. Ra7 {The play on both flanks is at the end and now White can bring every piece over to the Queenside. The only vulnerable spot in Black's position is at b7. How can White possibly get at it? In spite of the terrible grip exerted by White's remarkable V-formation of pawns, the answer is not easy to see} 42... Kf8 43. Rh1 Be8 44. Rha1 Kg8 45. R1a4 Kf8 46. Qa3 Kg8 47. Kg3 {The Knight will have to be brought via d2 and b3 to a5 to intensify the pressure on the b-pawn. Before embarking on this maneuver White must rule out the possibility of ... Pe5 by Black} (47. Nd2 e5 48. fxe5 Nxe5 $44 {Black causes some trouble}) 47... Bd7 48. Kh4 Kh8 49. Qa1 Kg8 50. Kg3 Kf8 51. Kg2 Be8 52. Nd2 Bd7 53. Nb3 Re8 (53... Be8 54. Na5 Rd7 55. Nxb7 Rxb7 56. Ra8 $18) 54.
