It is an interesting site, with one caveat.
<quote>It is oft asked what does running one billion hands matter when I won't play that many in my entire life. The point is to increase the accuracy of the estimate of what will happen in the short-term.<end quote>
That statement is in direct violation of most modern decision-theory. In particular, what Tversky and Kahneman call the "Law of Small Numbers." It is also fairly well explored in Russo and Schoemaker's "Decision Traps." Or in almost any standard textbook on inferential statistics. In essence, the belief that short-run results will replicate long-term results is a myth. Wildly popular and almost universal, but a myth nonetheless.
Not my idea. I had it hammered into my head by some very short-tempered professors in graduate management classes. Useful stuff.
Good Luck
