Supercomputer programs like IBM’s Deep Blue have demonstrated their ability to outthink human chess players. There is one game, however, where humans still reign supreme: Go. Yet here too their grip is beginning to loosen.

MoGo, a program developed by researchers from the University of Paris, has even beaten a couple of strong human players, using the Monte Carlo method, a form of statistical sampling. It is ranked 2,323rd in the world.
