Diagram 1: King, a-pawn and bishop versus king

Diagram 2: King, a-pawn and knight versus king

Diagram 1: With a black king on a yellow square the position is drawn, independent from the right to move. On a light grey square the position is lost, independent from the right to move. On a medium green square the position is of type (+/=), i.e. a nullzug position with advantage for White.

Diagram 2: With a black king on a light grey square the position in won for White, i.e. the position is of type (+/-).

Quintessence: There are no good or bad pieces, there are only won, lost or drawn positions.

Diagram 3: Without light pieces it looks as follows:

Diagram 3: King and a-pawn versus king

If we compare the positions of diagram 1 and 3 we come to the conclusion: The bishop doesn´t matter!
