Chess Board Riddle

There is an old Indian legend about a King who was challenged to a game of chess by a visiting Sage. The King asked "what is the prize if you win?".

The Sage said he would simply like some grains of rice: one on the first square, 2 on the second, 4 on the third and so on, doubling on each square. The King was surprised by this humble request.

Well, the Sage won, so how many grains of rice should he receive?
