This category is for the listing of subcategories of professional (and important amateur) players of all variants of cue sports, such as pocket billiards (including pool, snooker and English billiards), carom billiards (including three-cushion, straight-rail, etc.), and more obscure games such as bumper pool; and for general-resource articles relating to this topic that are not national/regional or game-specific in nature. No individuals' articles should appear in this category, only in a more specific subcategory.
It is highly dubious that a "Category:Obstacle billiards players" subcategory should ever exist here; there are no professional or even serious amateur leagues competing in any such game as of this writing, and no evidence that there ever has been in the past
