How Top Players Treat the Same Chess960 Position

One of the features of the Chess Classic Mainz events is that all chess960 games played in the same round use the same start position. After collecting a number of games (see CCM PGN Game Scores), I discovered that the diagrammed position had been used in 2007, and its twin had been used in 2008. Let's look at how some of the world's leading players treated the opening through the 10th move.


Start Position 034
(Twin: Start Position 919)
