Then, as no playing careercan ever be smooth and setbacks and disastrous performances are unavoidable, there are the matters of frustration, of floundering confidence, of doubting your directions, and of the painstaking search for ways to get better. These are heavy dues to pay, and a chess player quite truthfully places all his eggs in one basket. The risk offailing to justify a life-choice and earning just rewards in the end is very stark and real. No wonder, then, that serious chess is only for those who could sacrifice and dedicate themselves to a single purpose.
