This book presents more advanced chess principles, and it's a little hefty for a beginner (or a 7 year old, as I was the first time I borrowed my Dad's chess books), but for a more experienced player looking to improve their game, it's a pretty good resource.
I really don’t like writing bad reviews on anything but this translation into English is bad I don’t think the translator should have attempted this. I did not get past the preface before coming across major translation issues. This book has potential but needs a team of professional translators to truly convey the intended message.
Unhelpful due to format
This book could be useful for studying chess, but it just doesn’t work with iBooks. The diagrams being used to show board positions are often split between two pages, combined with how the symbols are spaced make it impractical to learn from.
Bad, I can’t see the graph
I can’t see the board,
