# Find The Shortest Mate

I struggled with this problem off and on for over a day before I finally hit on the right idea that led to the solution.

Yes, the problem with the 1.Rh4 Nh5 line is that the rook blocks the path to h8 for the queen if black takes at f4 with the knight on his second move. It took me a long time to even realize the line that goes 1.Rh5 Nxh5 2.Qh1 Nf4 was a mate in 3- I was blind to Qh8# and thus blind to even 2.Qh1 even though I found that move early, it seemed no improvement at all.

Assuming there are no typos in your solutions, then what about 1.Rh4 Nh5 line?
