1. gf3 2. Bg4 3. Be6 4. Ke3 and now only one of white's castlings is possible. Depending on which castling is possible, the solution continues with:

Note that 1. gf3? doesn't work: there is no solution after 4. Ke3 if white can only castle kingside.

Last moves were: -1. .. Ne7-f5 -2. d4xNe5 Nd3-e5 -3. f5xNg6 Nc1-d3 -4. e4xNf5 c2-c1=N -5. d3xRe4 b3xRc2. Further retracting involves unpromoting both uncaptured knights on c1, uncapturing c2xRd3, unpromoting both rooks on g1, uncapturing a whitesquared white bishop by one of the black queen-wing pawns, bringing this bishop to f1, and uncapturing g2xNf3.

Only one queen-move needed: Qh8-h7. The original white queen was captured on d1.
