Many strong chess players go on to successful careers as currency and stock traders, so I suppose there is considerable crossover in the pattern-matching and intuitive calculation skills required. But the aptitude for playing chess is nothing more than that. My argument has always been that what you learn from using the skills you have—analyzing your strengths and weaknesses—is far more important. If you can program yourself to learn from your experiences by assiduously reviewing what worked and what did not, and why, success in chess can be very valuable indeed. In this way, the game has taught me a great deal about my own decision-making processes that is applicable in other areas, but that effort has little to do with natural gifts.
