Here is another correspondence chess game that I played back in 1978. This is also from the first round of the Golden Knights Postal Championship. We both missed a few things in this chess game, but I found enough good ideas and moves to eventually win.
Back then, the US Chess Federation (USCF) had different rating scale for correspondence chess than the Elo system that was used for Over the Board chess. Back then, a 1300 cc rating was Class A. I don’t remember exactly when they made the switch, but when the did my cc rating jumped from somewhere in the 900 range to about 1800 points.
My opponent got out of the main lines early and allowed me to play a sideline that often favors Black, especially of White does not know this variation. I believe that my notes below explain what happened in this chess game well enough.
