34.Qd4 Qe7 35.Bd3 White's pieces are carefully placed to limit attacks upon the white king and the advance of the Black knight

35...Qc7 [35...Qe1+ 36.Kc2 ]

36.g4 Kf7 37.h4 Nb6 38.h5 gxh5 39.gxh5 The h7-weakness eases the win.

39...Qc6 40.Be4! preferring to fix the weakness on h7 rather than capturing it immediately [40.Bxh7? Qxf3 41.Qxb6 Qd1+= ]

40...Qb5 41.h6 Qb3 [41...Qf1+ 42.Kc2 Qg2+ 43.Kc3 ]

42.Bc2 Qb5 43.Qd3 Forcing the exchange of queens

43...Qxd3 44.Bxd3 and here, the win is trivia because white has the attack upon the h7-pawn, the passed b-pawn, and no danger of perpetual check.
