Pachman considered Modern Chess Strategy, published in 1959, to be his best book and his book Checkmate in Prague recounts his treatment at the hands of the Communist. The latter book is fascinating reading as a personal account of his life and I highly recommend it.
In this game Pachman demonstrates how to use an open file to attack an opponent's King. Of course, the engines, as they almost always do, found some loopholes in his analysis. But, that does not matter because we don't play engines. What is important are the ideas and strategies that we can use against human opponents who don't calculate variations by the millions.
