ChessBase is a personal, stand-alone chess database that has become the standard throughout the world. Everyone uses ChessBase, from the World Champion to the amateur next door. It is the program of choice for anyone who loves the game and wants to know more about it.
Before we get to the slumming here are some interesting statistics compiled with the help of ChessBase 10.
The graphical presentation of draws, wins and losses shows quite vividly the difference between the three groups. Apparently the stronger the event the more draws we are likely to encounter. And the smallest number of black wins. In weaker groups there are considerably more decided games, and more end in a victory for Black.

Group A: The draw average in the top group is rather high, with 14 games drawn in 24 moves or less. The shortest draws were Radjabov-Dominguez in 14, Radjabov-Aronian in 15 and Adams-Radjabov in 15. There ere only six black wins, with Ivanchuk losing three and Wang Yue two with the white pieces. Karjakin scored the greatest number of white wins, three, followed by Aronian, Dominguez, Morozevich and Movsesian with two white wins each.
Group B: There were only three games in less than 25 moves, one of them a win by Short aganist l'Ami in 19 moves. Reinderman, Sasikiran, Vallejo and Werle lost two games each with the white pieces. Caruana won four white games, which was more than Hou Yifan, l'Ami, Navara, Short, Vallejo and Volokitin, who won two white games each.
Group C: The shortest draw in this tournament was a 12-mover between Holzke and Bitalzadeh in round seven. There were only two more games drawn in less than 25 moves. Oleg Romanishin lost three white games, Gupta, Howell, Iturrizaga, Nijboer and Pruijssers lost two white games each. Hillarp Persson won four white games, followed by Leon Hoyos, Iturriziga, Howell, Gupta and Bosboom with three white wins each.
In the above graphs, generated by ChessBase 10, you can see the number of games (y-axis, 0-5) that were played in 12-99 moves. The longest game in Wijk aan Zee so far was played in Group C: Anish Giri, the youngest player overall, defeated Oleg Romanishin, the oldest player, with the black pieces in a bishop and pawn ending in 99 moves.
The performance takes into account the average rating of the opponents and the score of the player. Levon Aronian's 2826 means that against the opposition he has faced so far one would expect a player with that rating to score as well as he did.

With the Wijk aan Zee tournament having its final rest day today, we once again turn our attention to the B and C Groups. Only two rounds have been played since our last report, and the leading situation in the B Group has not changed that much. Draws with Mecking and Motylev have left Nigel Short half a point clear, with a group of five players now hard on his heels: Caruana, Kazimdzhanov, Motylev, Navara and Volokitin. As reported two days ago, David Navara had already won one of the daily Ivan Sokolov Expert's prizes, for the best game played in each round. In the ninth round, he added another, with a very nice demolition of a sadly out of form Sasikiran.

1.e4 c5 2.Nc3 d6 3.g3 Nc6 4.Bg2 g6 5.d3 Bg7 6.f4 Rb8 7.Nf3 b5 8.a3 e6 9.Be3 Nge7. 9...Nd4 is more usual in such positions, preventing the advance d3-d4. 10.d4 b4 11.axb4 Rxb4 12.dxc5 d5?! 12...Rxb2 looks a better try, with a murky position after 13.e5. 13.exd5 exd5
14.Ne5! Nxe5 15.fxe5 d4. If he does not take the piece, Black is clearly worse, so Sasikiran decides that he may as well have some material to suffer for. However, the position after taking the piece proves to be hopeless. 16.Bg5! dxc3 17.Qxd8+ Kxd8 18.bxc3 Rg4 19.0–0–0+ Ke8 20.Bf6! Bxf6. The text loses simply, but after 20...Rg8 21.Rd6 Black is tied hand and foot. Against the threat of Rhd1, the only attempt to defend is 21...Ra4 22.Kb2 Ra6 but then simply 23.Rxa6 Bxa6 24.Ra1 is overwhelming. 21.exf6 Ra4 22.c6! Better than taking back the piece on e7, since the latter is not going anywhere. 22...Bg4 22...Nf5 23.Rhe1+ Be6 24.c7 mates. 23.Rd2 h5 24.c7 Bd7
25.Bc6! A most elegant final blow. 1–0. 25...Nxc6 26.Re1+ Kf8 27.Rxd7 forces mate in 15 (!), as Fritz 11 politely points out. [Click to replay]
For Sasikiran, the top seed on rating, the tournament has turned into an absolute nightmare. After losing to Efimenko with white the following day, he is now rooted to the bottom of the table, with just 3/10, and is losing Elo by the hatful. The other 2700-rated player in the group, Vallejo, is also failing to shine, having just +1 at this stage. In round ten he was instructively outplayed by Kazimdzhanov, who gave a textbook lesson on the subject of weak pawns.

The final three rounds of the tournament should be great, thanks to the luck of the draw. In tomorrow's 11th round, Short faces Navara with black, and he has black against Caruana in the final round on Sunday. Other key match-ups in the final few rounds include Motylev-Volokitin tomorrow, Volokitin-Navara on Saturday, and Motylev-Kazimdzhanov on Sunday!
In Group C, the lead remains in the hands of Tiger Hillarp Persson, who is half a point ahead of the young Filipino, Wesley So. The latter's challenge has been strengthened by back-to-back wins with the black pieces, in rounds nine and ten. At the other end of the table, it is very sad to see veteran Oleg Romanishin propping up the field, with just 3/10. Despite falling back after his good start, Manuel Bosboom remains the source of much of the most entertaining chess played in the event. Sadly, he lost the ninth round game against Holzke, which he needed to win for a GM norm, but he bounced back in typical fashion the next day, to smash Bitalzadeh.

The draw for this group has also thrown up a potentially decisive clash in
the closing rounds, as Hillarp Persson and So meet in the penultimate round,
on Saturday. Today being my birthday, I am now off to celebrate – if that
is the word – the expiry of yet another of the Biblical threescore and
ten, but I will be back again tomorrow evening, with a report on round 11 of
the A Group.
