Actuary Michael Shackelford, also known as “The Wizard of Odds,” offers video poker and other gambling advice on his web site www.wizardofodds.com. And it's a step or two more advanced than the info I had in today's gambling section.
He details video poker situations and what cards players should throw away and what they should keep.

He ran the situations through a computer to determine the best percentage play, based on playing “Jacks or Better” machines and the accompanying pay table.

“The correct way to figure out what to do is cycle through every way the replacement cards would come up and take an average what to win. There’s no practical way to do that with a pen and paper; there’s computer programs that do that for you,” he said.
