Qb6 {The former champion of Europe Nisipeanu has earned enough criticism
because of his opening choice in this important game. Wojtaszek has cooperated
with Anand in the team helping him against Topalov and thus is theoretically
very well prepared. What is more the variation of the Poisoned pawn with the
moves 7...h6 8.Bh4 included is widely tested on the computer servers. Despite
the fact, that Black is playing in this line in the style of a "drunken
sailor" white players have not been able to punish him for this undue courage.}

and Nisipeanu chooses the most popular one. In the special database that I
have the privilege to consult there are more than 1mil computer games. From
them in 8,000 games the position on the board was tested! Despite everything
the most promising for the future could be the retreat 17.Qe1 tested more than
2,500 times. If these games should fail to convince you, that chess has
changed thanks to the computer age then nothing probably ever will...} (17. Qd3
