Horrible analogy in my opinion. Who exactly are you playing against, in jazz? Critics? Who cares if the musicians recognize your licks as being memorized? How are they going to check mate you, exactly? By pulling another Pat Metheny? Is the point in jazz to checkmate other musicians? What context was he talking in? Are the other musicians listeners, or part of the band one is playing in? Why are jazz purists so arrogant? Don't they have other things to live for besides their music?
