It is about which rook should be captured, if you have the choice. Due to my extremely risky play in a Street Chess game on the weekend, I gave my opponent exactly this choice. He could either capture on the kingside, although I would be able to recapture straight away. Or he could grab the rook on a8 with impunity. In the end he took the rook on a8, but this allowed the remaining rook to join the attack. I guess I was lucky that my opponent chose the wrong rook.
