Don't remember where this one comes from:(Paraphrased)
"Which rook to move to the open file? Weigh all the pros and cons of using either rook. Double check. Once you have decided which one to move, move the other one."
No wait a second, move the other one.
Hold on now, it was right the other way round.
Actually let me change that.
No I'll keep it the same as it was.
Maybe I'll let the rooks decide for themselves.
touche!
touché mové
