One legitimate strategy for video poker advantage play is to hit the progressive jackpot games really hard when the jackpot is over a certain amount. Since the payback percentage for a video poker game is based on the % chance that each payout will occur times the amount of the payout, obviously an ever-growing progressive jackpot at the top end will eventually result in a positive expectation game. I've heard that entire teams will take over banks of progressive video poker games when the jackpots reach certain levels. (I guess if you live in a jurisdiction where it's legal to gamble online you could try this strategy on the Internet too.)
