Yeah Bf5 is the greek gift killer. Before you greek gift you should look out for it. That and Kg6 are the most important defensive moves
I play the Colle system with white. I know it's not the greatest opening for white because of it being too defensive, but about 60-70% of the time it opens up greek gift possibilities if black doesn't see it coming. Now I will know to watch for Bf5 before launching that attack.
