What is a Rake Chase? Rake chases are poker promotions which are incentives for players to rake more and reward them generously for that. In contrary to a rake race, you don’t compete against other players , but instead chase your own individual targets. In order to hit the points targets you need to play a certain amount of poker hands or tournaments for real money. As soon as you hit the points requirement, you have secured yourself the amount of money, which was preset for the respective level.
