FM Egor Lashkin (FIDE Rating 2459) has just published his newest in-depth theoretical research - Principled Repertoire against Vienna and Ragozin. Providing an opening repertoire for White against two of the most respectable responses to 1.e4, requires hard work, subtle understanding, and a lot of dedication. After analyzing the arising positions for months, FM Lashkin managed to create practical problems for Black in all directions. Sometimes, his in-depth analysis goes to the endgame! And what is even more astonishing, the author also explains how we could put pressure in the arising endgame positions.
The current database consists of 8 very huge theoretical chapters, 10 model games, a Memory Booster, and 15 interactive test positions.
