I do not agree on that as preparing against GM Anand is not very easy. I think
he has a very wide opening repotoir and can play most any position exelent,
given a suffisently long time control. Remeber he won the 40/2 games 1 1/2 - 1/2
last time if I remember right!

I think Jeroen can build a complete new book until the match, making van Welys
spesific preparation useles. He probably know this very well, so if he prepare
much at all, he is going to look for known computer weakness in Rebel!
