Tata Steel Rd.5: Anand, Carlsen win, Grischuk loses to Wang

Viswanathan Anand applied systematic pressure on Jan Smeets until the Dutch GM blundered and gave the World Champion the sole tournament lead. Magnus Carlsen did pretty much the same to Erwin l'Ami, only to blunder the won position to a theoretical draw – which the amazingly determined Norwegian GM went on to win! Alexander Grischuk lost to Chinese GM Wang Hao.
