Positional Repertoire against the Dutch Defence 

The Dutch Defence has the reputation of an opening, which leads to sharp and complicated struggle. The former World Champion Mikhail Botvinnik contributed much to the popularity of the Stonewall System, proving its viability for years on end at the highest level. In recent times strong grandmasters like Nigel Short and Predrag Nikolic used it with success as well, while Vladimir Malanjuk's trademark was the Leningrad variation.
The modern engines show that it is not easy for White to get an advantage in the main lines.
Instead of studying long theoretical lines (with no advantage guaranteed), GM Kiril Georgiev provides a positional weapon that is entirely based on understanding - 1.d4 f5 2.Bf4

In this extensive survey, Roiz comes up with a number of rare concepts and novelties in topical positions. At the very least, we can say that his suggested repertoire creates tons of practical problems for Black.

Tricky Repertoire against King's Indian Defence (1h 46min Running Time) 

GM Boris Avrukh introduces his suggestion in the following way: "Thе move 5.Nge2 is usually considered merely as a surprise weapon against the KID, but it actually contains more venom than it might seem. I was quite sceptical about it at first because the knight does not seem to belong on g3 square when Black already has a pawn on g6. However, one of my students had great results with this system (often called Hungarian System) as White, so I decided to check it more deeply. After careful analysis, I came to the conclusion that this is indeed a very playable system for White that could even form a base for a long-term repertoire and not only a temporary weapon. Black needs to show very good home preparation not to be worse out of the opening, which can be seen in the analysis below."

This partner product is based on a video group lecture by GM Avrukh.

“Milking a cow.” This is how once Bronstein described the Ruy Lopez opening. Despite the heavily explored lines this remains one of the most colourful and rich openings ever. The complex nature of the arising positions, the huge variety of tactical and positional ideas make it a must for every chess player.
The more we study and the deeper we dive into the Ruy Lopez the more and more secrets will be revealed and the better the understanding of the structure and the typical ideas would become.

Complete Repertoire against Alekhine and Scandinavian 

Zahar Efimenko prepared a database for White against the Alekhine Defence (1.e4 Nf6) and Scandinavian Defence (1.e4 d5).
Both are relatively rare but quite provocative openings in the sense that Black lures White into pushing his central pawns in the opening, only to attack and undermine them later. Such an approach is often dangerous in shorter time controls as Black gives up some space in the centre and then tries to launch a counter-attack while waiting for White's mistake as he is defending his central pawns.

Another similarity between the two is that in both cases Black puts a piece on d5 (a knight in the Alekhine and typically the queen in the Scandinavian Defence) as early as move 2. In some cases, there are even overlaps in the type of position that arises out of the opening, such as the Scandinavian gambit (2.exd5 Nf6) which can lead to an Alekhine-Defence type of position once Black recaptures on d5 with the knight.
The database, which consists of 15 chapters and 15 test positions, can naturally be divided into two parts.
