Quote from Cutten:
Isn't this just semantics. There are two types of gambling - betting when you have no edge, and are doing it either for the thrill, or the hope of a big score; and betting when you have sized up the odds and think you have an edge. To call them both gambling, the same term, is rather misleading IMO.
One of them is gambling in the sense that Joe Schmoe thinks of it. The other is speculation, trading, investment, professional handicapping etc. A skilled poker player at a table of fish is no more gambling than Wal-Mart are when they speculate on customer demand for a new store.
