Ok, here is her suggestion.
57...Qh1+ 58.Ke2 Qxg2+ 59.Kd3 Qf3+ 60.Kc2 Qxb3+
[d]8/p1p5/Pp1p2nk/1P1B4/2P1Ppr1/1K4p1/R7/3R4 b - -
I think she stoped here and said black is much better.
My thought :)
Without calculating variation you could get a bad bishop - good knight ending
that should be a win (in theory) because of the extra pawn:
[d]8/p1p5/Pp1p3k/1P1Bn3/2P5/1K6/8/8 b - -
or even with one rook left you could get something like this.
[d]8/p1p5/Pp1p3k/1P1Bn3/2P3r1/1K6/5R2/8 b - -
With keeping the knight on the board, black has the resource that exchanging
rooks is bad for White.
