This guide is in addition to BlackDragonX's solution. Make sure you have played all the tournaments and won them so you have enough money and need somewhere in the 600-700 range of knockouts. I also decided to play the $750 Tunica event 2, but I used a turbo controller. The reason for Tunica 2 is because you only have to go through 27 players and because it is no limit.
Turbo the following three buttons in this order: A button, up directional, left directional. This way, you are going all in every hand, either knocking a player out or getting knocked out. Once you are knocked out of the tourney, it will continue until there is a winner. Then it will reload to the main menu, select the same tournament, and repeat the whole process.
I know this may not be faster than the other solution, but it is for those who don't want to play this game to knock out 1000 by themselves. If you are lucky enough, you may be able to get the remaining poker hands you need.
