Let's learn a tactic!

I hated tactics for the longest time.  My teammates had to drag me kicking and screaming into them....  I was always getting them wrong..

But practice, practice, practice.  I'm getting them more often now.   I am to a point now where I can sometimes recognize them in games and that's actually a HUGE step.   

I had a game the other day where I did pretty well.  At one point, I had a candidate move but didn't play it as I wasn't sure it was the right thing to do. 

But it would have been a beautiful move and led to a wonderful tactic!  My stronger teammate went over this with me and we explored what I could have done.  (Remember my teammate once said I have good intuition but have trouble knowing WHY something is a strong move?  Prime example right here...)

Anyway, this was a new tactic for me as I hadn't heard of it before.   I'll discuss what it is in the puzzle.  

It's a beautiful tactic.  I hope I get a chance to use it!
