I think it isn't possible.

White has still all pieces, so all black pawns must have been on there own row.

Black has lost one pawn, which is explaining the dubble pawn of white, but the dubble pawn is on the g, and not on the h! But black is missing his h-pawn.

Are you really sure this is possible?

The game started like this:

1. Na3 h6
2. Nb1 h5
3. Nc3 h4

then black had to go to the bathroom. the naughty white player placed an extra knight on g3, and continued with:
4. Nb1 hxg3
5. hxg3.

Nope! Black moved out his h pawn, freeing his rook, which was eventually captured by white's h pawn, doubling pawns on the g file. Then, with a little help from white, black's h pawn marched down to the 1st rank and was promoted to a rook.

OK, but it is possible in 21 plies. 😛

(Before BigDogg logs on, I realize I should have asked 'how could' rather than 'how did'.) 🙂

1.Nf3 h5 2.Rg1 Rh6 3.Rh1 Rg6 4.Rg1 Rg3 5.hxg3 h4 6.Nc3 h3 7.Nb1 h2 8.Nc3 h1=R 9.Nb1 Rh3 10.Rh1 Rh8 11.Ng1 is the fastest.

However, it would be more interesting if the move order was exact...
