5.d4 <For a fine specimen of this variation of the Giuoco Piano, the reader may refer to Walker's "Chess Studies," No. 602, page 105. The attack in the game alluded to is conducted by Jaenisch, the defence by Der Lasa.>

8...Nd8 <In many of his games at this opening Mr. Cochrane used to withdraw the Knight to his own square. The Pawn at Q. fifth hampers the opponent, but at the same time shuts out the assailant's Bishop.>

14.Nf1 <14.Qf3 seems to be both safer and more effective.>

18.f3 <This is very hazardous. 18.Qh3 would have been sounder play.>

25.Rg1 <White having managed the opening somewhat carelessly, plays from this point with remarkable vigour and precision.>

27.dxc6 <The Black Knight having gone over to the King's side, White can make this exchange of Pawns without any detriment to his game, and the more so as his Bishop is thereby restored to light and freedom.>

30.b4 <To protect his well-posted Pawn on the extreme left, previously to making a demonstration on the right wing.>

32...Rg4 <Black ought to have exchanged rooks.>

33.Nf5+ <By this series of moves Black must lose his passed Pawn. White can then avail himself of the services of his well developed infantry.>

41.Rxc6 <Covering the advance of his own Pawns, and materially retarding the offensive movements of his adversary.>

55.Rd8+ 1-0 <White must make a Queen with a check, and also win the Rook immediately.>
