The organisers if the Mainz Chess Classic have announced the tournament will not be taking place this year. The usual reason, a lack of money, is the major reason for its demise, and it is hard to argue with that. Also hinted at by the organisers is the paradoxical effect of it being an event somewhat out of the ordinary (Chess 960, Rapid Chess etc) making it popular with players, while at the same time being taken less seriously by the same players.
Also in doubt are a couple of other events like Linares and Sofia. It seems that the GFC is still biting organisers with sponsors a little shy of putting up big dollars for big names.
