Conveniently

There are some 1.7 x 10 to the 29th methods of playing the first ten moves of this ancient and storied game. (The Greeks, clever as they were, didn’t even possess a symbol or number for any number larger than ten to the fourth, a myriad.) This being so, it becomes comprehensible why, while chess has ebbed and flowed through history, it has never been successful as a method of channeling the human mind to that combat of a higher sort.
