    1. Bd1 is necessary for the mate in four because it covers the g4 and h5 squares.

    Of course it is better to take a pawn and give checkmate, instead of just giving checkmate.  It is like a bonus pawn.  If the value of the move is considered mathematically then you are looking at (∞ + 1) or just ∞, and those are mathematically equal; but it is not necessary to look at these as a one-dimensional sum.  In a two-dimensional plane a rectangle that is zero height and ∞ length has area zero, but if has height 1 pawn and length ∞ (checkmate pawn equivalent points) then the area is ∞, so that is much better. In this calculation the unit of area is square pawns, denoted P^2 or pawns^2, or in Algebraic Notation, just ^2.

    @Cavatine, what are you talking about? So what if the rectangle has a square pawn level of near infinity? In a tournament its worth one point and that's it. Really man, this is not the place to show off mediocre math jargon.

    A lot of people were confused a bit about white's/black's first move.

    1. Bd1 takes away a critical flight square from the black king, namely h5, and has a mate threat. Here's an example of what happens if black plays a different move:

     

    Why did you say a lot of people were confused?

    Very nice.  I've had sticky bishops in real games.  The discovered check was elegant.  Thanks chess.com.  That one was worthy.
