Brilliant by misclick

Hello guys, I was playing a chess game and I did this move by a misclick and I thought it's a blunder but turned out to be a brilliant. Can anyone tell me what's the purpose of this move (I took a bishop by the way). 

After king takes rookni think it is Qe5 check and its a fork on the rook and king

You can analyse your game to sew the full lines

that's what I did but he blocked with the bishop

I ran out of reviews heh
but in the self analysis it showed that the best moves were going to lead to a either a checkmate or winning a queen

Nice. If black king takes the rook ...Kxe7 then Qe5+, which is blocked by the bishop .. Be6 as you said. So black's rooks are now connected and white doesn't take h8. So White then responds Bg5+ which also frees up the a1 rook and protects the f1 square thwarting blacks potential Mate in 2 (Bh3, Qf1#) If the king goes back to the back tank then Qxh8+ If not then Qg7+ causes all kinds of problems.

You can analyze your game.

"Game review" is bad, as you can see from the picture (what are those arrows, they are insane).

Use "Analysis" instead.

Btw, it's ridiculous how inept and terrible Game review is. I am astonished again and again.

There might even be a line with Nxd5 after king takes leading to winning the queen but I'm not sure

I have a slight feeling you don't like Game Review

I think you could take the rook in that case putting the king in check again then takee we the other rook.

???

if the king takes the rook, you win it back with a fork

That's not as simple, as it was said before.

1. Rxe7+ Kxe7 2. Qe5+ Be6 defends the rook.

Now the engine's top choice is the weird 3. b3, kicking the queen and opening another diagonal for the bishop. There are several lines depending on where the queen moves, but Stockfish says white is +12.

You probably misread the position. Black isn't threatening mate, and isn't going to in the foreseeable future. Unless black can make 3 moves in a row.

This position is fully winning. After the king takes the rook, You will play Qe5+. If opponent blocks the check with the bishop, Qg7+ if again opponent blocks with bishop, Bg5+ and this move either ends with a checkmate position (up to M11) or winning a queen and a bishop. Because after that if the black king leaves the bishop, You capture the bishop and later, you play Bf4 which is very strong. If after Qg7+ black plays Kd6 , you play the Bf4+ and black is forced to sac their queen to capture your Bf4 and if they don't, Kc5 is M1 and Kc4 is M2.

If after Qe5+ black plays Kf7, You will play Bh6 and then, for black Rg8 is M7 and Be6 (engine reccomendation) ends up with losing both their rooks. Re8 will be +29.9 (Depth: 21 moves) (Black has no options to save the game) (in this specal position (Re8) your only good move is Qg7+! and the other moves will make you worse than black!)

Let's back to the first move again. If after your rook sac, black doesn't take it and plays Kd8, It's a M11.

After your rook sac, black will either lose 1 queen, get checkmated, lose both 2 rooks, lose B+Q , lose one R. That sacrifice is fully winning. Sorry I made it long and hard to read

Yes, very hard to read. I just can't figure out what move do you recommend after Be6 that wins material immediately. What you wrote makes no sense to me.

And after Qg7+ black just have 4 options: Bf7 , Kd8, Ke8 and Kd6. Ok . Bf7 is long to explain. Kd8 and Ke8 both lose both 2 rooks (bcause Qxh8+) And Kd6 loses the queen. (Bcause you play Bf4+ and black has 3 options, 2 of them are getting mated, 1 of them is Qxf4 and this is sacs the queen.)

My 2nd previous quote is this: *After Be6, the best move is Qg7+ and that will win material anyway." My previuos quote is the continue.
