What distinguishes the expert from the amateur in chess is partly tactical fluency, but also the ability to map out long-term patterns, in other words to visualise a distant goal. Some champions were distinguished by their talent for rough-and-tumble tactics; among such illuminati one could mention Alekhine, Tal and Kasparov. Others, such as Capablanca, Reti, Nimzowitsch, Smyslov and Karpov, stood out by virtue of their ability to foresee routes to victory that could only have been vaguely discernible to the average chess eye.
