A good question.Here are some very limited thoughts.
I suggest that we distinguish between rules external to the gameor sport that set it up such that it can begin -- e.g. rules thatdefine the conditions under which participants take part -- and theinternal rules that define how the game is played, such as permitted'moves'. A violation of an external rule is not so much a violationof this or that particular rule, as an attempt to subvert the gameentirely. Not doping is an external rule, and likewise the rulesgoverning permitted equipment, the size and shape of the court/field/ route. Rules like travelling in basketball, or committing afoul, are internal rules. (It may be that this distinction cannot berigorously maintained, and that some rules appear to fall into bothcamps.) Nevertheless, we seem to be able to then say that mostinstances of things we call ' cheating' fall into the infraction ofan external rule.
However, there are circumstances where the infraction of aninternal rule is generally considered cheating. To me, the mostobvious example is diving in football/ soccer. Although it looks likea violation of an internal rule, diving is a deliberate attempt todeceive the referee, and thus to subvert the rules of the game. Forthat reason, I suggest it is analogous to an external ruleinfraction.
Not an entirely adequate answer, but it may be a start.
