Can anyone see why this solution was wrong?

EDIT: ignore this, literally saw it 10 seconds after I posted

Topic. I'm white and it was my first move. 

I've gone over what feels like every move black could make and I can't find a single way black can avoid checkmate here. I'm assuming that either I missed something or there's a quicker way to checkmate. 

Wow I just saw it.. Qg2. Nvm I'm stupid. 

Qxg2#

I think you take the rook with bishop and if kings takes, Qd6 Ke8, Qe7#, so you won an entire rook for free

The reason this move is wrong is because black can take the bishop with the queen and there is no checkmate left

I mean Qf6 btw

Also for Qd6 it's Qd6+

1. Re7+ Kf8 2. Rxf7+ Kxf7 3. Qf6+ Ke8 4. Qe7#

1. Bxd8 Qxg2#

it doesn't work

Oops

After Qf6, if black takes the bishop with the rook, there's Qe7#. If black takes the bishop with the queen, there is Qxf7#.

I just realised taking bishop is bad bcuz of Qxf6

Qxf7

But then black can play Rd7 if you play Qf6 so zi think this this is why it's wront

If black plays Rd7, there is Rc8+ and black would have to block with Rd8. Then Rxd8 would be checkmate.

1cbb the mate in 4 works and I think if 2...Ke8 then 3.?Qe7# right

Sry for the question mark

If 2... Ke8, then Rd7+ and black would have to go back to f8, then since the f7 pawn isn't there, Qf6 would be checkmate.

You could play 3.Re7# or 3. Qe7#

Oops I keep forgetting the queen isn't there
