That will list all of the mates that there are, but not give you the unique positions.
For example the mates after.
1. e3 f6 2. e4 g5 3. Qh5#
is the same position as after
1. e4 g5 2. Qf3 f6 3. Qh5#
but Fritz would list these as different mates.
But you are right, it is a good way to check an answer, just like putting a tactics puzzle into Fritz is the best way to check the solution to a chess tactics problem 🙂
Or getting in a car, and driving 26.2 miles is the best way to "run" a marathon lol
The fritz "Show all legal moves" can help also. For example the first time I tried this, I missed the tempo killing moves like Ba6 that you would never play in a real game, because they just hang a piece. You have to "think outside the box" to find them all.
