I vaguely remembered an ancient thread on this very topic, and managed to dig it up.
Basically, the answer is: Depends...what ability do you want to cover it? Not really a satisfactory answer, but honestly, "playing chess" doesn't fit neatly under any of the canonical abilities, so it more or less boils down to where did you learn to play and what kind of knowledge do you have of it? I, personally, am loathe to make new abilities will-he-nill-he, but I think this would be a very justifiable exception.
