Carlsen's Kd2 vs Wang Hao might be the worst move I've ever seen him make in a classical chess game. Yes, tactical blunders and stuff happens, but this... You can't call this a blunder, I don't even know how to call it
I was in this chess camp this weekend and we were all watching this game live. About 10 people, all rated 2100-2300. After Kd2 the entire room just went nuts, we thought it is an error in the transmission or something.
Seriously, if you ask any 1600+ player what move he would consider in that position h5 or Kd4 would be an answer 100% of the time. I don't understand how could Carlsen play it..
