on some message board I found this text: "Such games as Go, Gomoku, Chess, Checkers, Othello have a character of schematic games - this means that exist formulated patterns of moves which make possible attainment of the victory in spite of even a lot lower IQ and analytical skills. It is visible very clearly on the example of Gomoku or Checkers, and a difference between Chess and Gomoku is only a difference of degree but not a principle - what is often not sighted and many people treat attainments in chess as indicator of intellectual level, what is very delusive. There exist also games that are free from such weaknesses and can really corelate with real IQ and analitical skills, some card games like Bridge, also board games like Mastermind or Supermind. In each from such games, important part play randomness. Correlation between Chess and IQ is very often negative, exists for example the schema of the game, which made possible obtainment of title of world champion, it relies on the so called ′game with pawns′ or 'checkers style', such technique used R.Fischer how works this pattern can be seen using the program Chessmaster 10th edition, one ought to place: white-Fischer, time-blitz 5 minutes, opponent can be about 1800 elo and the time at least 20 minutes, in this simulator it is visible very pellucidly on what relies this schema on this solution are leaning most effective at present chess engines such as Shreeder, Fritz, Hiarcs etc. of course Russian chess players always were and are using schemata of game" what do you think about it ?
