The research literature on chess playing and intellect is quite extensive. It is now well accepted that training and practice are very important in developing chess expertise. There is also some degree of innate aptitude for chess playing, that appears to be independent of IQ. It is easy to accept this fact when you consider that Kim Peek (basis for savant character in the film Rain Man), despite a phenomenal memory, scores well below average on general IQ tests (wikipedia).
So returning back to the author, Staffan A. Svensson, it is intriguing that he should feel that he is "not a good enough chess player" to test the ideas he discusses. Svenssen's considerable intellect is without doubt when you learn that he is a member (source) of Sigma Society V (IQ>180), Prometheus (IQ>164), Ultranet (IQ>164) and Mensa (IQ>132), excellent scores on several tests and the highest score on the LS-36. Humility is a great virtue.
