		1:  "“Unlike other games in which lucre is the end and aim, [chess] recommends itself to the wise by the fact that its mimic battles are fought for no prize but honor. \nIt is eminently and emphatically the philosopher’s game.”\n – Paul Morphy",
		2:  "“The beauty of chess is it can be whatever you want it to be. \nIt transcends language, age, race, religion, politics, gender, and socioeconomic background. \nWhatever your circumstances, anyone can enjoy a good fight to the death over the chess board.”\n – Simon Williams",

		8:  "“Chess holds its master in its own bonds, shackling the mind and brain so that the inner freedom of the very strongest must suffer.”\n – Albert Einstein",
		9:  "“Chess is a war over the board. \nThe object is to crush the opponent’s mind.”\n – Bobby Fischer",

		11: "“The game of chess is not merely an idle amusement. \nSeveral very valuable qualities of the mind, useful in the course of human life, are to be acquired or strengthened by it… Life is a kind of Chess, in which we have often points to gain, and competitors or adversaries to contend with.”\n – Benjamin Franklin",
		12: "“As proved by evidence, [chess is] more lasting in its being and presence than all books and achievements; the only game that belongs to all people and all ages; of which none knows the divinity that bestowed it on the world, to slay boredom, to sharpen the senses, to exhilarate the spirit.”\n – Stefan Zweig",
		13: "“Chess doesn’t drive people mad, it keeps mad people sane.”\n – Bill Hartston",

		23: "“When you see a good move, look for a better one.”\n – Emanuel Lasker",
		24: "“After a bad opening, there is hope for the middle game. \nAfter a bad middle game, there is hope for the endgame. \nBut once you are in the endgame, the moment of truth has arrived.”\n – Edmar Mednis",

		33: "“The passed pawn is a criminal, who should be kept under lock and key. \nMild measures, such as police surveillance, are not sufficient.”\n – Aron Nimzowitsch",
