While thinking about the marvels of the fool, I came across the fact that the presence of the fool slightly encourages sacrifices. For example if both fools are present on the board and it's at least ok to sacrifice an exchange, say a rook for a knight, then the side with the knight has it's fool imitate a rook and other pieces where the side with the rook imitates a knight and other pieces. So this is also an small levelling effect when making unbalanced exchanges.
