"I consider Mr. Morphy the finest chess player who ever existed. He is far superior to any now living, and would doubtless have beaten Labourdonnais himself. In all his games with me, he has not only played, in every instance, the exact move, but the most exact. He never makes a mistake; but, if his adversary commits the slightest error, he is lost."
"[Paul Morphy] just appeared from nowhere and it was only thirty or forty years later that people understood why he was so dominant. His understanding of chess at [that] point was at least forty years ahead of the rest of the world. For the era in which he lived the kind of chess he played was unbelievable."
"In Paul Morphy the spirit of La Bourdonnais had arisen anew, only more vigorous, firmer, prouder... Morphy discovered that the brilliant move of the master is essentially conditional not on a sudden and inexplicable realisation, but on the placing of the pieces on the board. He introduced the rule: brilliant moves and deep winning manoeuvres are possible only in those positions where the opponent can be opposed with an abundance of active energy... From the very first moves Morphy aimed to disclose the internal energy located in his pieces. It was suddenly revealed that they possess far greater dynamism than the opponent's forces."
"Reviewing the history of chess from La Bourdonnais to the masters of our day right up to Lasker, we discover that the greatest stylist was Morphy. He did not look for complicated combinations, but he also did not avoid them, which really is the correct way of playing... His main strength lay not in his combinative gift, but in his positional play and general style. Morphy gained most of his wins by playing directly and simply, and it is this simple and logical method that constitutes the true brilliance of his play, if it is considered from the viewpoint of the great masters."
"[I play in] the style of Morphy, they say, and if it is true that the goddess of fortune has endowed me with his talent, the result [of the match with Emanuel Lasker] will not be in doubt. The magnificent American master had the most extraordinary brain that anybody has ever had for chess. Technique, strategy, tactics, knowledge which is inconceivable for us; all that was possessed by Morphy fifty-four years ago."
"How much more vivid, more rich does the figure of Morphy appear before us, how much clearer does the secret of his success and charm become, if we transfer ourselves in our thoughts to that era when he lived and created, if we take the trouble to study, only a little, his contemporaries! Then...in London and in particular in Paris, where the traditions of Philidor were still alive, where the immortal creations of La Bourdonnais and McDonnell were still in the memory, at that time, finally, when Anderssen was alive, and with brilliance alone it was hardly possible to surprise anyone. The strength, the invincible strength of Morphy- this was the reason for his success and the guarantee of his immortality!"
"If the distinguishing feature of a genius is that he is far ahead compared with his epoch, then Morphy was a chess genius in the complete sense of the word."
"To this day Morphy is an unsurpassed master of the open games. Just how great was his significance is evident from the fact that after Morphy nothing substantially new has been created in this field. Every player- from beginner to master- should in this praxis return again and again to the games of the American genius."
"There is no doubt that for Morphy chess was an art, and for chess Morphy was a great artist. His play was captivated by freshness of thought and inexhaustible energy. He played with inspiration, without striving to penetrate into the psychology of the opponent; he played, if one can express it so, "pure chess". His harmonious positional understanding; the pure intuition, would have made Morphy a highly dangerous opponent even for any player of our times." ~ Vassily Smyslov[citation needed]
"A popularly held theory about Paul Morphy is that if he returned to the chess world today and played our best contemporary players, he would come out the loser. Nothing is further from the truth. In a set match, Morphy would beat anybody alive today... Morphy was perhaps the most accurate chess player who ever lived. He had complete sight of the board and never blundered, in spite of the fact that he played quite rapidly, rarely taking more than five minutes to decide a move. Perhaps his only weakness was in closed games like the Dutch Defense. But even then, he was usually victorious because of his resourcefulness."
"Morphy was the first positional player who, unlike his Romantic rivals, understood the strategic basis for attack. He wrote nothing more than a few game notes and played fewer than seventy-five serious games. But his exploitation of open lines prepared the way for Steinitz's scientific treatment of closed positions and the era of modern chess."
"La Bourdonnais [a great player, b. 1795 - d. 1840] died young in London, and the goddess of Chess, Caissa, very much grieved, mourned for him and forgot to inspire the masters with her sunny look. A dreary time then came over the Chess world. The masters played a dry style, without enthusiasm, without imagination, without force, and the Chess fraternity was full of the wrangles of the mediocrities. It is true, the goddess soon repaired her omission. She flirted – Goddess! pardon me this vulgar expression, but the coarse human language does not know the shades of meaning such as undoubtedly you would be able to express by means of Chess pieces – she flirted, I beg to say, with the English historian [and renowned authority on Shakespeare, whose name has been given to the style of Chess pieces we now use] Staunton and prevailed upon him to organize in 1851 an international chess tournament in London, during the great International Exposition of that year. And then – fickle Goddess – she gave her love to a young mathematician, the German Anderssen, and inspired him to superb combinations. And then -- oh the weakness of her – she spied with her great sunny eye in far distant Louisiana a boy, highly talented; she forgot all about Anderssen, guided the steps of the young American, fell in love with him, introduced him to the world and said triumphantly: “Here is the young Paul Morphy, stronger and greater than master ever was.” And the world listened and applauded and cried “Hurrah for Paul Morphy, the King of Chess!”
In Paul Morphy the spirit of La Bourdonnais had arisen anew, only more vigorous, firmer, prouder. He never formed columns of Pawns for the purpose of assaulting a firm position as Philidor had taught, he always fought in the centre, only a few Pawns in front, and if he needed the lines open, he sacrificed even these few advanced posts. Should the adversary make use of Philidor’s maxims, Morphy’s pieces occupied the gaps in the oncoming mass of Pawns and opened up an attack, so as to leave the enemy no time for slow, methodical maneuvering. Paul Morphy fought; on good days and on bad days, he loved the contest, the hard, sharp, just struggle, which despises petted favourites and breeds heroes.
But then the Civil War broke out in the United States and broke the heart and mind of Morphy.
...When Paul Morphy, despairing of Life, renounced Chess, Caissa fell into deep mourning and into dreary thoughts. To the masters who had come to ask her for a smile she listened absent-mindedly, as a mother would to her children after her favourite had died. Therefore, the games of the masters of that period are planless; the great models of the past are known, and the masters try to follow them and to equal them, but they do not succeed. The masters give themselves over to reflection. One of them reflects a long time and intensely on Paul Morphy, and gratefully Caissa encourages him; and the greatest landmark in the history of Chess is reached: William Steinitz announces the principles of strategy, the result of inspired thought and imagination...
...Principles, though dwelling in the realm of thought, are rooted in Life. There are so many thoughts which have no roots and these are more glittering and more seducive [sic] than the sound ones. Therefore, in order to distinguish between the true and the false principles, Steinitz had to dig deep to lay bare the roots of the art possessed by Morphy. And when Steinitz after hard work had bared these roots, he said to the world: Here is the idea of Chess which has given vitality to the game since its invention in the centuries long past. Listen to me and do not judge rashly, for it is something great, and it overpowers me...
... The world would have benefitted if it had given Steinitz a chance. He was a thinker worthy of a seat in the halls of a University...And I who vanquished him must see to it that his great achievement, his theories should find justice, and I must avenge the wrongs he suffered..."
