To play chess, the ulema declare, is detestable according to Imam Abu — Chess

"It is an abomination to play at chess, dice, or any other game, for if anything be staked it is gambling (maisir), which is expressly forbidden in the Quran; or if, on the other hand nothing be hazarded it is useless and vain. Besides, the Prophet has declared all the entertainment of a Muslim to be vain except three: the breaking in of his horse, the drawing of his bow, and playing and amusing himself with his wives. Several of the learned, however, deem the game at chess lawful as having a tendency to quicken the understanding. This is the opinion of ash-Shafi`i. If a man play at chess for a stake, it destroys the integrity of his character, but if he do not play for a stake, the integrity of his character is not affected."

"[C]hess is not a game for dictators for numerous reasons. One, its transparent. It’s all information hundred percent available so you know exactly what you have, you know exactly what your opponent has. You don’t know what he or she is thinking, but you definitely know what kind of resources your opponent can use to hurt you, to damage your position. Also, chess is very much a strategic game so you have to think long-term. Dictators don’t think long-term. Dictators, especially who are in power for so long as Putin is, they have to work on the survival mode. Because it’s all about today, maybe tomorrow morning. Everything that helps us survive is good. Because the moment the dictator thinks long-term, he’ll definitely miss guys from his own entourage hitting him in his own back. The game that defines dictators much better is poker because it’s about bluffs. It doesn’t matter whether you have a strong hand or weak hand. You can have a weak hand, but if you’re comfortable bluffing, raising stakes, and if you can read your opponent."

"Yet to calculate is not in itself to analyse. A chess-player, for example, does the one without effort at the other. It follows that the game of chess, in its effects upon mental character, is greatly misunderstood. I [...] assert that the higher powers of the reflective intellect are more decidedly and more usefully tasked by the unostentatious game of draughts than by all the elaborate frivolity of chess. In this latter, where the pieces have different and bizarre motions, with various and variable values, what is only complex is mistaken (a not unusual error) for what is profound. The attention is here called powerfully into play. If it flag for an instant, an oversight is committed, resulting in injury or defeat. The possible moves being not only manifold but involute, the chances of such oversights are multiplied; and in nine cases out of ten it is the more concentrative rather than the more acute player who conquers."

"We must finish once and for all with the neutrality of chess. We must condemn once and for all the formula "chess for the sake of chess", like the formula "art for arts sake". We must organize shockbrigades of chess-players, and begin immediate realization of a Five-Year Plan for chess."

"Its a useful mental exercise. Through the years, many thinkers have been fascinated by it. But I dont enjoy playing... Because it was a game that was born during a brutal age when life counted for little. Everyone believed that some people were worth more than others. Kings. Pawns. I dont think that anyone is worth more than anyone else... Chess is just a game. Real people are not pieces. You cant assign more value to some of them and not others. Not to me. Not to anyone. People are not a thing that you can sacrifice. The lesson is, anyone who looks on to the world as if it is a game of chess, deserves to lose."

"That which has reached us from the discoveries of their clear thinking and the marvels of their inventions is the (game) of chess. The Indians have, in the construction of its cells, its double numbers, its symbols and secrets, reached the forefront of knowledge. They have extracted its mysteries from supernatural forces. While the game is being played and its pieces are being maneuvered, there appear the beauty of structure and the greatness of harmony. It demonstrates the manifestation of high intentions and noble deeds, as it provides various forms of warnings from enemies and points out ruses as well as ways to avoid dangers. And in this, there is considerable gain and useful profit."
