I do not take Keene seriously, he wrote and sold many books, but of low quality.
Of course a knight and a king are best to blockade, but that does not make them stronger.
Here a game by Tarrasch that Nimzovich gave in My System to illustrate the bishop's pair:

Most of Keene’s books are trash. No disagreement there. His book on Nimzowitsch and one or two others are notable exceptions. The others that seem okay are one on Stein (I don’t have it) and his book on becoming a Grandmaster, which I have and have read.
