The Quick Pin

I have playing a few games, and I have discovered a quick pin. It does have its flaws, however I will post it for now as the unfinished version. The pin is quite an enjoyable one; keeping a knight from fear of the death of the queen. I got this move from the Legall's mate, although it is a nice move to use when you aren't in a situation such as the Legall's mate. Give me comments and/or feedback, please.
