I often wonder whether the visualization of the various types of chess-related graphs is helped along by playing competitively. This would seem to fly in the face of a recent peer-reviewed study in the sense that there would be a high-level benefit (ie teaches skills that can be transferred to other domains) to chess if this line of thinking is correct, namely in the field of chess-related math.
On the other hand, the study seems to be very thorough and is one of the few peer-reviewed articles available on the subject. One would expect if there were some high-level gain to playing competitively then the test that shows this would be repeatable. However, there has been mixed results, as the above article claims. Perhaps the field of chess-related math is only chess-related in that the only skill that transfers is knowing how the pieces move, without any regard for strategy. What do you think?
