Tactics Practice - Pinning 11-12

I've changed the way I am naming these posts.  Might help anyone reading them keep better track of what they contain.  Also will help me know what problem comes next.  I've also started trying to check them with my computer prior to posting, so if you have any questions about any problems please ask.  I'll add analysis.

This one threw me for a loop.  Don't think mate.  Where this puzzle ends is mate in 10 (assuming you are a super-computer.)

Alright.  Got work in the morning, so that is all for tonight.  Happy Tactics!
