Here is a fascinating case about regulations, reported by the BBC:

Derek Kelly, 46, argued poker is a game of skill so he did not need a licence under the 1968 Gaming Act, as the law requires it only for games of chance.

But the jury at Snaresbrook Crown Court disagreed and took less than two hours to find him guilty of organising games at his Gutshot Club in central London.

[…]

Graham Trembath QC, told the jury that they alone would decide the verdicts.

He said: “Is poker a game of mixed skill and chance? That is for you to decide. The prosecution submit that common sense dictates that it is.

“Why do we say that? We say that because before a game can start someone shuffles the cards.”

Where does the threshold lie for chance and skill? I’m having a hard time thinking of a game that doesn’t involve chance at least to some degree…

Or maybe we should just say that luck was not on the side of the defendant this time around.
