I have chess books on most aspects of our favourite game. I now find that the best type for me are those such as this one where a top player annotates his/her games giving their insights in explanatory form rather than the (somewhat overwhelming) variation spaghetti. At a lowly 1500 level I am not trying to find the ultimate truth in a position but simply hoping to understand what is going on.
Example books include those recent-ish ones by V. Bologan, B. Gulko and of course Fischer's 60. Judit's book is an excellent example of the genre. She achieves this by inserting a paragraph, sometimes two or three, of informative discussion notes at key moves in her games. That said, there is certainly enough variation analysis at the most critical junctures to satisfy the most avid analyst.
It is those conversational elements, almost mini chess lectures, which I find the most valuable part of the book. An example may help ...page 178... "Having occupied the open file first, Black (Judit) can dictate the circumstances under which the exchange of rooks will be carried out. Capturing on a2 [by her] would [only] lead to a draw as a fortress could be built which is even easier to defend than that examined previously. Instead I invited my opponent to carry out the exchange himself and improve my structure in the process..." Although the passing of the capture in this example isn't so deep of itself it is in the associated notes about the possibility of the defensive fortress, its resilience and the lulling of an opponent into a drawish state of mind which provides the key insight. The book is full of such gems.
Have a look at the book's Contents page and judge for yourself how many interesting aspects of are covered.
This reveals just how heavily the Polgars were coached and how rapid their progress was. One can see Marin has a hand in writing this as I recognise his influence in annotations, very clear game annotations. Concentration is on tactics and endings not so much on openings though some model games inTaimanov /Scheveningen Some interesting pictures e.g of the young Polgar's opening files or Two of the sisters playing blindfold, howevera few of the pictures are repetitive and waste space.
