You thought you were going to St. Louis but it is really in Chesterfield itself.
I live in St.Louis and go to a chess club called, "Chess Cardinals." I play OTB here and I am now 1300 USCF after a few months of going there. I am trying to find a new club near the Chesterfield area of St.Louis. If you know any, please let me know. ALSO, please subscribe to my youtube channel linked here!
