Somehow go always makes its way into online conversations about chess. The Wikipedia article on computer go suggests that humans are better at calculating long sequences in go than in chess because the pieces in go stay where they are unless they're captured. This seems reasonable to me, though I'm no better than a beginner at go (I'm probably around the equivalent to an "amateur low dan" at chess, and can do what you suggested a go player of that level should be able to do in replaying and memorizing games.) Also, it's not really fair to compare international titles in go, of which several are contested every year, to the world championship in chess, which is only contested every other year. A better comparison might be some of the major international tournaments like Wijk aan Zee, Linares...or perhaps this year's Nanjing Pearl Spring tournament, in which Carlsen decisively defeated a field consisting of five other top-20 players: Veselin Topalov (currently world #2, and the challenger for the world championship to be held later this year), Wang Yue (#9), Peter Leko (#12), Teimour Radjabov (#16), and Dmitry Jakovenko (#19). Carlsen scored 8/10 (six wins, four draws) -- no one else scored above 5.5/10.
