[edit] 8. b8=N# is not tight
8. b8=N# doesn't have a unique solution.
1. a4 d6 2. a5 Kd7 3. a6 e6 4. axb7 Nc6 5. Rxa7 Nce7 6. Rxa8 Nf6 7. any Ne8 8. b8=N#
Changing the problem to 7... b1=N# would make it tight.
Or am I missing something?

7... b1=N# doesn't have a unique solution either.
1. d3 a5 2. Kd2 a4 3. e3 a3 4. Nc3 axb2 5. Nce2 Rxa2 6. Nf3 Rxa1 7. Ne1 b1=N#
The order of the moves d3,e3,Nc3,Nf3 can be changed.
