To improve, which is the hardest

Learn to play chess is easy. My first games with my father showed me the way. But now, after my standard openings jumper-king, I did not do much against him. This book then allowed me to improve myself, I went to use the "Alekhine defense" successfully.
I play less frequently now, but this book well worn on the shelves of my library, leaves me a happy memory, that of learning easy alternatives; it deserves the attention of all who want to get out of the usual parts, they certainly do not become champions, but they shrug of a good standard.
A strongly advise the idea that we will gain after reading it, goes with the pleasure of discovering what the other can do.
