in the Petrov- 5.5/6! Who dares claiming that the opening can be borning after
that?} 3. Nc3 {Surprise! Anand has played the Four Knights back in 1992-96 via
a different move order though...} Nc6 4. Bb5 Bb4 ({Ruinstein's recipe is

The last round of the tournament on the next day was rather peaceful with only one game being decisive. The world champion Magnus Carlsen exploited a blunder by the birthday boy Rauf Mamedov to finish the tournament clear first a full point ahead of Vishy Anand.

It looks amazingly like Cheap Archeage Gold ballistic gel. So, if you extrapolate, you can imagine what it Archeage Gold would look like if you submerged a person in liquid nitrogen and shot them with a twelve gauge. At least that's what I did. Far Buy Archeage Gold less gruesome than the unwarranted murder of a gummy bear.
