Here is a game from the first international event that I played on the ICCF server. Both of us had provisional ratings of 1800 points at the start of this. Now, my established rating on ICCF is 2027. My opponent’s established rating is now 2192.
The opening that I played is known as both the Modern Defense and the Robatsch Defense. I usually call it the Modern Defense , even if I start off with a different move order. In chess openings there are two schools of thought. The first one is called the Classical School and it teaches players to occupy the Center with pieces and pawns. The second one was developed by Aron Nimzowitsch and Richard Réti and is called the Hypermodern School of thought. This school of thought teaches players to not occupy the Center but to attack it from the wings instead. I have played both styles and which one I will use in a particular game depends on my mood and what my opponent is rated. Also, if I know or suspect that my opponent is going to play some kind of anti Sicilian opening I will play the Pirc or Modern Defense.
Although we both played a couple of second-best moves there were no outright blunders until I decided to trade queens on move number 20. That lead to the loss of a Bishop for a pawn and then I resigned. I can’t explain that kind of a blunder in a correspondence chess game! At the time that I played this game I did not know that ICCF rules allowed me to use chess engines. If I had used an engine in this game I would not have made that blunder.
