If you activate the reference view in the notation window the program continually carries out a search in the background based on the current board position. It uses the games it finds to show useful information about the variation line being played.

 

There is a new column called “Hot”.

 

 

The board shows a standard position in the Spanish opening.

 

 

 

The main continuation is 8…d7-d6. However, the “Hot” column shows that at top level the continuation 8…d7-d5 is preferred. In the game list the games of the strongest players are displayed first.

 

 

The complete line of the fashionable jot line is shown as the main line. The number of games is displayed in which the hot variation was played.

 

The criteria for the classification as “hot” are the date when the games were played and the average Elo of the players.
