So, the challenge is to construct a proof game with this feature
ending in a pure mate (unlike the above "first example" where
g3 is guarded twice)? This works, then (C+ Popeye 3.41 in ~5.5 seconds):
Solution below. Andrew -- does this accomplish the task you had in mind?
1 g4 f5 2 g5 Kf7 3 g6+ Kf6 4 gxh7 g6 5 b4 Bh6 6 b5 Bg5 7 b6 Nh6
8 b6xa7 Rf8 9 h8=N d6 10 Nf7 Nd7 11 Nxd8 Rf7 12 Ne6 Nf8 13 Nf4 Be6
14 Ng2 Rc8 15 a8=Q b5 16 Qa3 b4 17 Qb2#
