user12017: I've been playing with the Chesscademy app for a while, solving some tactics (which I'm not sure is improving my chess, but it's a good puzzle to kill some time). Today I ran into one tactic that I failed to solve, though my play seemed to result in the same advantage as the one picked as an answer.
Since I'm a beginner at Chess, I might be missing something about the move that makes it a better candidate, so I decided to post it here and get some opinions.
Below is the move that the tactic claimed is right (Black then White):
[FEN "r1r4k/1p5R/3b4/4q3/B3P1Q1/1n1P3P/6P1/5R1K b - - 0 1"]

1... Kh7 2. Rf7 Kh6 3. Qh4 Qh5 4. Rh7 Kh7 5. Qh5+

My answer was basically the same, except instead of 3. Qh5 Rh7 I played 3. Qh5 Rf6.
So I could foresee one outcome from that play:
[FEN "r1r4k/1p5R/3b4/4q3/B3P1Q1/1n1P3P/6P1/5R1K b - - 0 1"]

1... Kh7 2. Rf7 Kh6 3. Qh4 Qh5 4. Rf6 Kg7 5. Qh5 (Kf6 6. Qh6) 

That opens up an X-ray attack on the bishop if the King captures the rook (5. Kf6 Qh6), though it can be easily defended if the king goes to a square next to the bishop.
Is there any reason why this play is worse than the original answer? Usually, when I thought I was right about a play I'd think for a while and find some reason why it was not a good one, but this time I'm not really figuring out why the original answer would be better than this one.

user7297: The problem is that 5. Qxh5 isn't check, so Black has time for some back rank tricks (instead of capturing the rook on f6):
[FEN "r1r4k/1p5R/3b4/4q3/B3P1Q1/1n1P3P/6P1/5R1K b - - 0 1"]

1... Kxh7 2. Rf7+ Kh6 3. Qh4+ Qh5 4. Rf6+ (4. Rh7+ Kxh7 5. Qxh5+) Kg7 5. Qxh5 Rc1+ 6. Qd1 Rxd1+ 7. Rf1 Rxf1#
