> Gambling means a game of chance/luck. Court cases over poker, regardless of which way the decision goes, hinge on whether the Court is convinced that poker is a game of skill, rather than luck.

I think it really just has to have an element of uncertainty. For example one can gamble on chess tournaments. I suppose one can broadly construe an element of "luck" if Magnus somehow botches a game, but it strikes me as something quite different from whether or not one's lottery numbers come up.

As you say, poker is the archetypical example of a skill game with an element of chance. Backgammon is another good example. I would say darts is another example that falls further on the skill end.

As noted in another comment on this submission, it appears one can greatly increase the chances of regulators approving an activity by having former regulators on staff. Needless to say traditional finance companies enthusiastically hire those people.
