PG in 15.0 moves
(position after Black's 15th; find the gamescore)
That was a tough nut to crack. Black has only one spare move, which must be a queen move, allowing the h-rook to pass to b8. The white knight must make a detour towards g1, to avoid checking black. And the white d-pawn must lose a tempo for two reasons: to get the number of moves correct, and to avoid arriving at d7 before the e7 square is available for the black king.
