In the game the knight participates in a kingside attack which is just a little harder to bring off as the major pieces have to relocate.33.d5Rb734.Qc3White would have been better advised to claim the fourth rank with34.Qc4as this denies the knight any moves. The exchange of queens is not to be feared - passed pawns become more significant as the other material reduces.Qg6would then be a good continuation for Black, with the advantage in a complex game.34...Nf435.Qd2Ng6eyeing up the e pawn which is hard to defend, and also the h4 square36.Rc636.f4Rab8threatens to get to b1 and Black has plenty of threats36...Qa7+37.Kh1Nxe5one dangerous pawn disappears but the d pawn can still be a powerful force38.Rc3Rab8Creating an attack is the best use for an extra piece.39.Rcc1Rb240.Qc3Qf2the black pieces close in for the kill and just have to get there before the d pawn queens41.Rg1Ng6f4 will be an excellent square for the knight42.d6Rc2the queen is forced off both the c file and the the long diagonal42...Nf4immediately is also good43.Qa5Nf444.Raf1Nh3!a neat finish involving smothered mate45.d7Qxg1+46.Rxg1Nf2#0–1
