Phony Benoni: <Newzild> Your line is clearly better for Black than the one we considered, but stil seems to fall a bit short. Let's go the position where you ended your analysis, after <54...g3>
click for larger viewThe key move for White again is <55.Bf3!> Now after <55...Nf2 56.Kxg3! h1Q 57.Bxh1 Nxh1 58.Kg2> Black's knight is trapped and the a-pawn rules. Black does have a better choice in <55.Bf3 Ng5> 
click for larger viewWith the threat of 56...Nxf3, and the knig cannot recapture. Now essentially three things can happen here. 1) Tired of Black having all the fun, White might decide to slip in a Fancy Dazzler of his own with <56.a6 NNxf3 57.a7>. White is promoting the pawn all right, but it's Black who is wining after <57...Ne1+ 58.Kh1 Nd3! 59.a8Q Nf2+ 60.Kg2 h1Q+ 61.Kxg3 Nxe4+ 62.Kf4 Qf1+ 63.Ke5 Qxc4 64.Qxe4 Qxe4+ 65.Kxe4 Kg6! and wins. 2) White can adopt the simple course of <56.Kxg3 Nxf3 57.Kg2!> Black will now have to move his knight to the queenside, so that White wil safely capture the h-pawn and play thepawn up ending. I think this should be a win for White, but with these crazy nights you never can tell. 3) The sane course of <56.Nd2>. With both White minor pireces helping out on the kingside, the pawns will fall and White has nothing to fear but a possible K+B+N vs. K ending, which in those days you learned how to win even before you began to play chess.
