Updated analysis:

[B]34 Bh3+[/B]

If [B]34 ... Nf5 [/B][B]35 g4[/B]

If [B]35 ... Bd4+[/B] [B]36 Kh1 [/B](NOT 36 Kg2 Nh4+ 37 Kg3 g5) and continues as in another branch.

If [B]35 ... Nf3+[/B] [B]36 Kh1 [/B](NOT 36 Kg2 Nh4+ 37 Kg3 g5) and continues as in another branch.

If [B]35 ... Ne7[/B] threatens to swap knights so as to lessen our attack. We should avoid that swap except on our own terms, I think.
If [B]36 g5+ Kf7[/B] (not ... Kd5 or ... Ke5 37 Nxe7) [B]37 Nd6+ Kg7[/B](forced)[B] 38 Rb7[/B]
Here note that Black cannot protect the N/e7 with his B on this move 38. (E.g., 38 ... Bb4 39 Rxe7+ Kf8 40 Re6 hxg5 41 Rxg6)
If [B]38 ... Kf8 39 gxh6[/B] threatening 40 Rb8+ Nc8 (forced) 41 Rxc8+ and 42 Rxc3
If [B]39 ... B-move(except Bd4+) 40 Rb8+ Nc8 41 Rxc8+ Ke7[/B] we're a rook up.
If [B]39 ... Bd4+ 40 Kh1[/B] and Black still cannot stop Rb8+ except by sacrificing his B, so game proceeds as in other branches.
If [B]39 ... Nf5 40 Rb8+ Ke7 41 Nxf5+[/B]
If [B]41 ... gxf5 42 h7[/B] and 43 h8/Q Bxh8 44 Rxh8.
If [B]41 ... Kf7 42 h7[/B] and 43 h8/Q Bxh8 44 Rxh8.
If 39 ... ???
If 38 ... ???

If [B]35 ... Nd6[/B] [B]36 g5+
[/B]If [B]36 ... Kd5[/B] (not ... Kf7 37 Nxd6)
With the Black knight on d6 instead of e7, trading knights helps us by ensuring our g-pawn's advance (or material gain).
[B]37 Nxd6
[/B]If [B]37 ... Kxd6 38 gxh6[/B] and[B] h7 etc.
[/B]If [B]37 ... hxg5 38 Nf7 etc.
[/B]If [B]36 ... Ke5 37 Nxd6
[/B]If [B]37 ... [/B][B][B]Kxd6 38 gxh6[/B] and[B] h7 etc.
[/B][/B]If [B][B]37 ... hxg6 38 Nf7+
[/B][/B]If [B][B]38 ... Kf4 or Kf6 39[/B] ????[/B] We're up a rook for a pawn.If [B][B]38 ... [/B]???? [/B]We're up a rook for a pawn.

[strike]If [B]35 ... Ng3 36 hxg3[/B][/strike]

If [B]35 ... Nd4 or Nd6 or Ne3 or Ng7 or Nh4 36 g5+[/B] and now we have two branches, depending on Black's king move:

If [B]36 ... Kd5 or Ke5 or Ke7 37 gxh6[/B] and?

If [B]36 ... Kf7 37 gxh6[/B]
If [B]37 ... Kg8[/B]
If [B]38 Rb7[/B] and now Black has a wide variety of possibilities, so I'll just list every legal move:
If [B]38 ... Ba1 or [/B][B]Bb2 39 ????[/B]
If [B]38 ... Bd4+ 39 Kh1 ????[/B]
If [B]38 ... Be5 39 ????[/B]
If [B]38 ... Bf6 39 ????[/B]
If [B]38 ... Bg7 39 Rxg7+ ????[/B]
If [B]38 ... Bh8 39 ????[/B]

If [B]38 ... Nb1 39 ????[/B]
If [B]38 ... Nb3 39 ????[/B]
If [B]38 ... Nc4 39 ????[/B]
If [B]38 ... Ne4 39 ????[/B]
If [B]38 ... Nf1 39 ????[/B]
If [B]38 ... Ndf3+ 39 ????[/B]
If [B]38 ... g5[/B] threatening ... Ng8 [B]39 ????[/B]
If [B]38 ... Kf8 39 ????[/B]
If [B]38 ... Kh8 39 ????[/B]
If [B]38 ... Nhf3+ 39 ????[/B]
If [B]38 ... Nf5 39 ????[/B]
If [B]38 ... Ng2 39 ????
[/B]
