The CSVN organises for the 10th time the International CSVN Tournament (ICT). Location is again "Leids Denksportcentrum", Robijnstraat 4, 2332 KE Leiden.

Later this year the 30th Open Dutch Computer Chess Championship takes place. To celebrate this, the board of the CSVN decided to invite some prominent programmers at the ICT10.

We are therefore proud to announce that

Don Dailey (programmer of the new 3000+ engine Komodo)

and

GM Larry Kaufman (Komodo, Rybka)

will attend ICT10 in person.

There will be two tournaments: the Programmers Tournament and the Users Tournament.
