There are only a few days left until the start of the 2016 Zurich Chess Challenge, so it's just about time to have a closer look at some statistics.

First of all, let's see how the players perform against each other in classical time control. The rows show the results of each player with the white pieces while the columns present the corresponding headups with black.

Calculating all individual results together, it's a little surprising to see the Armenian Levon Aronian clearly ahead of his rivals. Four percentage points are quite a gap on that level. On 2th to 4th place, the performance of Nakamura, Kramnik and Anand is almost equal, while Giri and especially Shirov are well below 50%. However, as usual these statistics have to be treated with a little caution: Giri's negative score mainly arises from his desastrous results against Kramnik and Aronian, while Anand can undoubtedly be called Shirov's personal Nemesis, as his overall performance is clearly in the Indian's favour (+13 =27 -2).

Classical ranking according to percentages:

2 Nakamura +22 =49 -18 46,5/89 52,2%
3 Kramnik +39 =130 -31 104/200 52%
4 Anand +31 =135 -25 98,5/191 51,6%
5 Giri +7 =47 -14 30,5/68 44,9%
6 Shirov +15 =76 =42 43/133 39,8%

Considering the time control that is applied in Zurich this year, the headups for Rapid are also highly interesting. Not surprisingly, the overall performance sees Anand clearly in front, followed by Aronian and Nakamura. Kramnik is a little below the 50% line, while Giri and Shirov can be found at the bottom of the table again. However, the results are a little distorted, as "old hands" as Anand and Kramnik have more than 100 recorded rapid games in the databases, while Giri has only played 18 "official" encounters so far.

6 Shirov +11 =42 -22 32/75 42,7%

Blitz is and has always been an important part of the Zurich Chess Challenge. The overall winner is determined by the rapid games, where a win is awarded 2 points and a draw one, and the blitz games, where win and draw count one, and half a point respectively.

Not surprisingly, Blitz rather favours the indisputed ICC bullet champion, Hikaru Nakamura, who is clearly ahead of his rivals by scoring a whopping 60,4% out of 48 games. Giri is now in 2nd place, still clearly above the 50% line, followed by Kramnik with 51,3%. One who is probably not expected to be at the bottom of the table is Viswanathan Anand with only 38,6%, which is mainly due to his very bad score against Nakamura and Giri (+2 =3 -7).

And finally the inevitable: An overall ranking table with all points of all three time controls brutally put together. According to these calculations, the American Hikaru Nakamura is a slight favorite to win the tournament - and indeed that's what he already did last year. But already a short glance at the bottom of the table makes it clear that it's not that simple - the Latvian Wizard Alexei Shirov will definitely not enter the stage of the Savoy Baur en Ville just to be the sacrificial lamb. I wouldn't be surprised if things turn out quite differently in the end...and I'm looking forward to an exciting weekend of world class chess!
