Fingerfehler

Norway Chess witnessed another amazing day. Round five saw three decisive games. Magnus Carlsen finally won his first game against Alexander Grischuk. However, it was the former world champion who stole the show as his win lifted him to the remarkable 4.5/5 and clear first place.
A game that I liked (ChessBase 13)
