Can you find the right move in this lesson?

This question was posted by one our kind members and here is the reply i managed to find, and to be honest, this was my second choice, the first one was to move the bishop, which was not good enough. So i came up with this and happened to be correct

Hope it was helpful

Thank you 

I could not find the correct move. My result was solved with hint ,  after i saw that the queen had to be sacrifised the rest moves were easy . solved 50%. 

You are better than that, Lachesis777, just take your time
