The repertoires below are just examples of what can be achieved using the editor. It is up to you to build your coolest openings theory!
The Traxler counter attack
An example of the Traxler counter attack can be downloaded here.
It is a reply from black to the fried liver attack. Highly recommended if you like dynamic games!
Queen pawn reply: a stockfish trap
If, just like me, your are out of ideas against a queen pawn opening, the following queen pawn reply can be downloaded here. It is short but it may be the starting point of a larger repertoire for black!
