While I am wary of saints and much prefer the company of sinners, it is no fault of Barry Greenstein that the commercial poker world has co-opted his private acts of charity to serve their public greed. And all of us non-Jews would do well to consider the Hebrew tradition of “Mitzvah.” (Not that this necessarily motivates Mr. Greenstein’s behaviour or that his motivations are any of my business.) “Ace on the River,” by the way, is an absolutely brilliant addition to the poker lexicon and, graphically, will never be surpassed.The monitors of this site would do us all a mitzvah by following through on their claim that inappropriate posters will be banned.
