This is a correction of a nice puzzle in the "open-close" topic which has many duals on the first and later moves. This is one straight run home! Sorry for the many black pawns. The price of integrity.

Very beautiful one! Thanks for sharing this!

You're welcome. 90% is not my contribution though, only the two extra black pawns!
Parece que el camino nace con 1.Tf8-Kg7/g8, 2.Tg8+-Kh1. 3.Ng7 y analizar como se llega al mate por ese camino.
That's right ChessReina though you probably meant 1. ...Kg1/g2 
The remainder of the solution is logical and not that hard! It's a mate in 7.
Replying a bit late but an incredible rewarding puzzle!
Thx! I'm not sure "late" exists here. Some respond to posts from 2007!
Thanks for this. I finally solved it with few tries.
Very beautiful puzzle!
I was looking for a while at this nice rook sacrifice line (mate in 8) but the solution is even better.

For fun I added a B-assigment as well. Again white starts and checkmates in 7 moves but after the first move of the A-solution was played! You can only solve the A-puzzle interactively, for B you need an analysis board!
