White has sacrificed two pieces to get the Black king into the open. What is the most efficient way to finish him off?
One of the great principles of attacking an exposed king is to make sure he can’t scamper back and head for cover. White achieves this by giving up one more piece! It also is a clearance move to allow the queen to move along the third rank. 1.Bb6 Qxb6 [1...Ne3 2.Rd4+ Nc4 3.Qb3#] 2.Qa3+ Kc4 3.b3+ Kc3 4.Rd3#
