Took a quick look at the game in question, first of all very dubious choice of opening for Black with that 4...b5, although White went on to push c5 in the opening phase.
On the 17.Bxh7 move, I would at best give it "?", 17...g6 18.Ng5 Nf5 19.h4 Nxh4 20.f4 Nf5 (maybe 20.d5 Nxe3 21.Qb2) 21.Qd3 Qb6 - at this point in the game I would say that White had lost any edge it gained during the poor opening choices of the Black pieces. 22.g4 Ne7 23.Qe4 Qc7! - very nice move for Black, which can now focus on gaining an advantage on the Q-site with its passed pawns, starting with a4!. Centre is defensible is White tries to pressure with d5 exd5 cxd5 Rd6.
24.Qe5?? - horrible move, gives Black the game on a silver platter. After the Q-exchange Black can push a4-b3 with ease creating immense pressure and blocking one rook on Rab1 after b3, White then has to withdraw Ne4 and Black can manoeuvre his Nc8, Bc6 and start activating both pieces to claim the Q-side. Black effectively plays with an extra piece, since Bh7 is blocked! ... a4 26.Rdb1 Nc6! - process of activating pieces is even quicker for Black.
But 25...Nc6? is too early, giving White Rf1!, forcing 26...Nd8. Still, I think Black has a small advantage here. 29.Rf2? again is inviting Kg7! followed by Nc6!!, and not Kg7 30.Rh2 Ra7 - which is slow and achieves nothing, since Nxf7 is countered by Rxh7!.
31.c5 Bd7 32.Kf2 Rb7 - even without Bc6 White is completely lost in this position, Black has only to start pushing those damn pawns.
35.d5? (exd5 exd5 Nxe5! Kd4 Nxg4!, if Kf4 then Nd3+! is deadly), but Black plays 35...Nxe5 36.c6 Nxg4+?? - very very very weak move, Re7! was the answer to c6, followed by exd5.
37.Kf4 Rb5 (imagine only 37...Bxc6 38.dx6 Nxh2 39.cxb7 e5+! 40.Kg3 Rb8 41.Kxh2 Rxb7 42.Bxg6 Kxg6 - position after is Black has two passed pawns + Rook versus Knight badly placed + Rook, I would play as Black in this position and win without problems)..
38.Kxg4 exd5 39.exd5 Rxd5 40.Rc1? inviting b3! 41.Rc4 1-0
What did you do, bribe him to resign?! White is lost here... after 41.Rc4 Rb5! with b2 in mind, c7 is countered by Bd7 with check if White does not move the King, followed by Rxg5, two passed pawns, one dead Bishop and a generally bad position give Black easy winning chances...
