Hmmm.... results can always be grouped-by using the gamelist sort feature.
But a proper resolved query would need a "count" feature... and rewriting
SQL is probably beyond the scope of the project. ! :)
Jose Chess already uses SQL and perhaps this query could be done in it.
Also, Scid's opening report already gives this information on a 10-year
timeframe.
