When talking about passed pawns, Nimzowitsch was the first teacher who taught about blockading them. Of course this has always been known to masters intuitively and were employed in their games. Nimzowitsch discusses his thoughts about Knights being excellent blockaders of passed pawns. In addition when we come to the concept of protected passed pawns, there is no better piece to blockade than the knights. They not only block the passed pawns, but they attack its protector! This is only possible because of the Knight's unique movement pattern on a chessboard.
When looking at a recent game of Caruana against Shankland, I was very impressed with the strategic depth and control he showed in the game.
