c) 1 … R(4 or 8)g7
2 R:d7
d) 1 … Q:f7
2 Be5+ any
3 Q:h7#
I was quite pleased to find this line rather quickly. Maybe it was possible because I have studied a lot of Fischer’s games and more or less have a feeling for how he would think, assuming this was what he chose.
1. f7 R8g7
2. Be5 R4g6
3. Bxg6 Qc6+
4. Be4 Qxe4+
5. Rxe4 Bf8
6. Rh4 Nb3
7. Qxh7#
An even shorter game results if white chooses 4. Re4 rather than 4. Be4.
4. Re4 Qxe4+
5. Bxe4 Bf8
6. Qxh7#
1. f7 wins immediately.
1. f7
if
1… Qxf7
2. Be5+ R or Q to g7
3. Qh7#
if
1… Qxd1
2. Qxh7#
1. f7, threatening
2. Qxh7#

I’m betting that its f7
1 f7 Qxf7
2 Be5+ Qg7 or Rg8g7 or Rg4g7
3 Qxh7#
or
1 f7 Rg8g7
2 f8=Q+ Rg7g8
3 Be5+ Qg7 or Rg7
4 Qxh7#
