Who is the power BISHOP OR HORSE?

@President_DonaldDuck : In other words: It‘s all in the mind

It's mind over matter.
If you don't mind.
It doesn't matter.

@President_DonaldDuck

but if pieces are not power, then how can it be who is the power BISHOP OR HORSE?

Why do you seek to ask me these questions for which the answer is already within you? You must clear your mind of all worldly concerns, focus, meditate, until the source of confusion is fathomed and your conscious mind reaches the transcendental area of being. Then the answers you are seeking will be revealed to you.

@President_DonaldDuck

gasp, who is the power BISHOP OR HORSE? is bishop!
