The OP's comments refer to "Weapons of Chess" by Bruce Pandolfini. An excellent book, appropriate for advanced novice thru intermediate players, which introduces fundamental concepts and techniques of positional-strategic chess.
The OP's assessment of the referenced text is incorrect.
I own the book. I just read the pages referenced by the OP. It is clear that the positions in Diagrams 75 and 76 are NOT the same, by comparing the different positions of White's Knight and Black's h-pawn in the two diagrams. Diagram 76 illustrates the position after White's knight has captured Black's h-pawn on h4 (Diag. 76), after said pawn had advanced to h4 from h6 (Diag. 75). There are no errors in the text, which describes how play proceeds before and after White's Knight captures Black's h-pawn.
I recently purchased this book.
The first section I read is Fianchetto.
An error already. Diagram 76 on page 97 does not match the text. Diagram 76 is in fact a repeat of Diagram 75 on page 96.
This is a significant editorial error.
Has anyone found other errors in this book?
