Here is one account, here is Levitt’s account of another round. In the latest he did very well indeed. Out of 900 or so contestants, I am hearing reports that he finished about #25, some sources are saying as high as #10. The pointer is from Scott Cunningham, tell us more if you know more.
So how many dimensions does intelligence have? Some top chess players, such as Etienne Bacrot, are switching into poker for the higher pay, though I suspect Levitt’s move is temporary rather than permanent.
Addendum: Here is Levitt’s account.
