lvcfThe Las Vegas International Chess Festival will be June 4 to 7 at the South Point Hotel. Prizes of up to $100,000, with $70,000 guaranteed to be awarded.

At the same time will be the Susan Polgar World Open for Boys and Girls, with sections for players up to age 7, 10, 13, and 18, divided by sex (not sure why they need to be divided by sex, but there you go).
