José Raúl Capablanca, the Cuban Genius is a former world champion (1921-1927) and there had been 8 continuous years where he didn't lose a single game. His book "Chess Fundamentals" is a short book written in a very simple language but has pearls of wisdom in it. Though I have read several other chess books, when I read this book I get the feel of Capalanca hand-holding us into every position in a subtle tone conveying the master techniques. I was touched by the tone and concrete judgements he provides in each and every lesson. It makes us look at Chess from Capa's eyes. All of a sudden, Chess becomes so simple and easy.
A chess prodigy by birth he was hailed for his exceptional instructive endgames. Here it would be right to recall what Fischer said about Capablanca.
Capablanca was among the greatest of chess players, but not because of his endgame. His trick was to keep his openings simple, and then play with such brilliance in the middlegame that the game was decided - even though his opponent didn't always know it - before they arrived at the ending. - Robert Fischer
Capablanca's games generally take the following course: he begins with a series of extremely fine prophylactic manoeuvres, which neutralize his opponent's attempts to complicate the game; he then proceeds, slowly but surely, to set up an attacking position. This attacking position, after a series of simplifications, is transformed into a favorable endgame, which he conducts with matchless technique. - Aaron Nimzowitsch
The below game between Capa and Nimzo is a perfect example for the above statement given by Aaron Nimzowitsch himself. Notes by Capablanca.
In the above game, as rightly pointed out 11... g5 by Capablanca was bold and wild. Breaking the rules, having the king in center, capturing the pawn looks crazy to us, but Capa is already having necessary plans to meet with 16... f6 followed by Kf7. Nimzowitsch was hoping on the opposite colour bishops for an equal endgame but Capa had already noted the broken Queen side pawn structure. Capa says here,
Notwithstanding the Bishops of opposite colors I did not hesitate to exchange. Those who wish to learn should do well in carefully studying this game. It is one of the finest endings I ever played, and I have had very often the great pleasure of hearing my opponent pay tribute to the skill displayed by me in winning it.
On move 23 Capa plays Re2, still going for exchanging. On move 29, Capa is clear that the ending is now completely won in all possible directions. Conversation between Nimzo and Capa about this game at a later point in time give in the above comments is a proof of it.
To be precise, after this point it should be considered like Capa is demonstrating his matchless endgame skills, the possibilities of winning the game in style as previously decided by him during the middle game itself, where as his opponents, here in this case Nimzowitsch are still playing the real game, working out ways to prove any drawing sequences. I wish we could borrow Capa's master techniques in our games. 
This is my first post in chess.com and bear with me for any errors. I hope to write much better articles in the forthcoming days.
