Checkmate By Pam-Krabbe Castling In A Unique PG


I've seen Pam-Krabbe castling in plenty of genres, but never in a PG. Simply composing a unique PG that has it is way too easy. Having it end it checkmate is much harder.

Unique PG 11.5
(= 12+13 )


Solution (?): 1. e4 d5 2. exd5 Kd7 3. d6 Kc6 4. Bb5+ Kxb5 5. c4+ Kxc4 6. dxe7 Qxd2+ 7. Bxd2 Kd3 8. Qf3+ Kc2 9. Bh6 Nxh6 10. e8=R Bd6 11. Nc3 Bg3 12. 0-0-0-0-0-0#

This is best effort so far if incorrect, as this is my first dabbling in unique PGs.

The fastest possible checkmate via Pam-Krabbe castling, by my calculations, is 10.5 moves. Feel free to try and create such a unique proof game.
