Hi jarkov. Welcome to the group. I too have a difficult time staying on top of upcoming events. I just check the major websites frequently. The biggest events are regular every year like Wijk aan Zee in January, Linares in February, Amber in March, etc. Did you know there is a World Championship Match scheduled for April?
thanks for having me. about 1900 on this site and glad to be invited to this group. I never watch enough prime chess matches because I can never find them. do you guys have a list of where each upcoming event is?
