Since Black can postpone mate for five moves that is the "main line" technically 3...Qh8 and 3...Qg3+ are both incorrect because they permit mate in 4 instead of 5, so they are variations of the solution - which consists of the loser dragging things out as many moves as possible.

Only that 5. g4+ isn't mate. 5. Rh8 is the correct response. This is mate in 6.

White to mate in 4 (or 6)

Nice, did you make it up or find it someplace?

BTW the correct heading is "Mate in 5" not "4 or 6" and the solution should be shown as follows:

1. Qg5+ Bxg5 2. hxg5+ Kh53. Rh8 Qc8+ (3...Qh8 4.g4#; 3...Qg3+ 4.Kg3 any Rh7#) 4.Rc8 f5 5.g4#

Thanks for the correction. I found this beauty in my tactics database.

Nice; I played fxg5+, I wonder if it makes any difference.

There is no difference.

Playing 3. Rg7 though is clearly losing, as white now cannot capture the black queen after 3... Qc8+.
