Ένα βιβλίο γραμμένο σε απλά και κατανοητά αγγλικά, με παραδείγματα από όλους τους χώρους των Μαθηματικών Ολυμπιάδων, με παρουσίαση των αντίστοιχων λύσεων αλλά και του σκεπτικού που οδηγεί σε αυτές.

“…It is a unique book. It seems there is a relative scarcity of books on advanced problem solving. Most of the literature on this topic is either on more introductory problems or presents its material in much the same way that Descartes criticises. One would be inclined to think that the latter are like foxes walking on snow but erasing their trails with their tails. Nikolaos defied the challenges and produced a book that throws light on the ideas and intricacies that lead to solutions for a variety of intriguing mathemati- cal problems. He draws his material mostly from challenging problems that have appeared in International Mathematical Competitions...”
Part of Prof. Michael Lambrou’s foreword.

“…, the purpose of the book is to present a plethora of problems from all areas of contest mathematics and to present not only their solutions but the thinking trails one could follow to reach them. There is a huge difference between the two approaches and the author strongly feels that the second proves to be a lot more didactic than the first one. Hopefully, as we said before, by the end of this book readers will be able to observe that a set of ideas to be presented tend to appear again and again; and that, if used on a regular basis, these will evidently hone their skills on problem solving.
In parallel, this book aims to serve one more purpose: To act as a companion/ mathematical coach to the reader, regardless of his/her geographic location, ability to have one available on a regular basis, or any other factors whatsoever.
It is also worth mentioning that, though the book is written in the English language, the author primarily wrote it in the hope that it aids to any extent towards improving the teaching of mathematics to gifted students in Greece, from early stages of competitions to members of the Greek National Teams.”
