Thomas Biedermann wins 13th North American Invitational CC Championship

Thomas Biedermann is no stranger to this column. He has been here many times before – he tied for first in the 16th US Correspondence Chess Championship and was second in the 18th.  He received his International Correspondence Chess Master and Senior Master title.  He played on Board 5 in the 20th Olympiad and on Board 2 in the Pan-Am games. And now he has annexed the North American Invitational Championship. Congratulations, Thomas!
