Why would you automatically reject this idea? Here is one plausible explanation for it.

* Spatial ability is an important part of chess
* Boys have an higher standard deviation of spatial ability than girls.
* If the mean of boys and girls spatial ability is the same, then both extremes would be dominated by boys. The boys with high spatial ability would typically dominate girls with high spatial ability when it comes to chess.

There are of course exceptions. I know an extremely talented young girl player, who routinely dominates skilled boys that are a few years older.
