...Presuming you can spot the idea!
See if I can guess the opening!! 🤣

[Note: this is my proposal for what might have happened during the first 10 moves. Black's position is so terrible, it behoves opening students to see why it's so bad. He has lost a Knight, without compensation, and has a severely undeveloped King side.]

1. d4...Nf6
2. Bg5...c6
3. e3...Ng4(?)
4. Q×g4...d5
5. Qd1...Nd7
6. Nf3...Nb6
7. c4...Bg4
8. Bd3...B×f3
9. Q×f3...Nd7*
10. Nc3...f6 (puzzle diagram)

Then comes this ~
11. Qh5+...g6
12. B×g6+...h×g6
13. Q×g6#

*Black seems to have 2 missing moves, and since this Kt position is awkward, perhaps he moved back after deciding to advance his f-Pawn. Black's fatal mistake was failing to recognize the power of Q & B on parallel, open diagonals.

White's dark Bishop has apparently reposed on g5 for 11 moves!
This has been an informative study. Thank you, porcho.
