My intuition was Nf3+, which was wrong, because there is not much white can do after Kh1.

Qxg7??

Sacrifice the queen!

I should have known the checkmate pattern.

This one I couldn’t see the move after Bc5+, but it seemed like the best move, and it worked.

I really didn’t see it…

…Bxd3?
Threatening the queen is better than threatening the rook.
I’d lose my bishop if I just take c5.

I thought if …Nxf3, Bxc7. I always worry about losing my queen. 😄

Not Rd8 because the trades won’t be fair.
