Do you see mate in 3 anywhere in this game?

I missed a mate in 3. There is somewhere, can you see without using engine?

I cant see one

Yes, I can (although it proved a bit difficult to avoid the notes of the Engenie). My solution however was 17... Bxf1... which I believe also works.

On move 17

17...Bg2+!! 18.Bxg2 Qxel+ 19.Bf1 Qxf1# i think

it's not hard , when g2 sqaure will be opened and bishop c8 will COME to h8

It's even easier when the notes spell it out for you.
