Cute Tactic
Here's a neat little puzzle I stumbled upon while using a tactics trainer from another site (sorry chess.com, I'm working on calculation more than pattern recognition... your tactics trainer is great too though :D).
Let's see if you can see all the way to the end without making a move (like in a real game situation.)
Good luck :D
