What does the "WR" stand for in "WR chess masters"?

Title. I was wondering and couldn't find it anywhere.

World Record? Maybe.

Women rule?

Named after Wadim Rosenstein, CEO and founder of the WR Group, the WR Chess Masters is a classical chess tournament which boasts the participation of 10 world-class Grandmasters. - :]
