Bishop or knight? An eternal dilemma!
The legendary Bobby Fischer would likely vote for the bishop. Other authorities like Nimzowitsch would prefer the knight. The truth is somewhere in the middle. Of course, it is clear a bishop usually dominates in open positions while the knight should be preferred in blocked positions.
But what does that “usually” mean? Are there exceptions?
Sure, a bishop can dominate even in a blocked position if the controlled diagonal is important. Further, the knight can dominate in open positions if there is a good outpost or influential place for it.
