Quoting from The Fiestas magazine, an advertising insert published in the Las Vegas Review Journal 6/26/08 (July 2008 issue, page 2, "Insider Info"):
We asked Ray Anzevino, director of operations for Fiesta Henderson, what the Fiesta winners know about playing and he said:Always split a pair of nines against a dealer's seven. Why? Because the book says so.
Yeah right.
Moral: never trust gambling advice published by a casino.
