The new opening report

The opening report is a comprehensive treatise on all variations of the current board position. Based on historical development, the success statistics of a variation in different Elo ranges are shown. The usual statistics sum up the success and popularity of a variation across all skill levels and thus ignore exciting information. The new report opens your eyes to how different openings work for different skill levels. For example, the Scandinavian is simply bad for Black at top level, but up to Elo1800 it is a convenient, theory-saving way to equalize.

Grandmasters don't like the Scandinavian

After 1.e4 d5 2.exd5 Qxd5 3.Nc3, 3…Qd6 is better than 3…Qa5 in nearly all Elo regions

Furthermore, the opening report shows 3…Qa5 as the most frequently played main system, which is also at the top in all treatises. But the practical chances are higher at every level with 3…Qd6. GMs know this, amateurs apparently don't. The opening report shows that the frequency of 3…Qd6 clearly increases with the Elo rating.

The opening report naturally provides the frequent variations for each main variation. There is a lot of help when deciding what to play: Statistics – of course. But also how popular the system is currently. Then the style of the variation with numerous statements about the positional character, which are known from the style report.

What character does a variation have?

Once you have decided on a move, you play the “instructive” games. These are clear winning games in which a strong player is better or equal against a weaker player after the opening and then shows how to do it right. The report also provides the typical moves of a piece and pawn advances. And finally, the typical tactics. Anyone who has solved all 40 tactical tasks, for example those offered in the Marshall Attack from the Mega Database 2026, has seen the most common motifs. This is practical training!

Plans in the new Reference Search

The new filters catch the eye in the reference search: For example, you can switch off the blitz games with a click. A player filter is also provided, which makes preparation completely easier. With one click you can switch back and forth between a player's repertoire and the overall search.

If you move the mouse over pieces on the board, their typical piece paths and the associated success rate are visualized: The better the results achieved, the greener the move:

The typical knight manoeuvre against Winawer: Nf3-g5-h3-f4-h6. On the other hand, Nf3-h4xg6 is not very successful
