That's the one volume english language condensation of the original multivolume (which came out in German? Czech?) right?
I studied that book (the single volume one in descriptive notation) I think that is a great book, a classic, and one of the very best books on the middlegame ever. I wish someone would reprint it in algebraic. Jeremy Silman's Reassess Your Chess is in a large part based on Pachman's book. I think the two books work well together. Hearing what is essentially the same thing, twice, in slightly different ways with different emphasis and examples, I found to be clarifying and illuminating.
I will get this book later, what do you think of this book compare to other strategy books?
