To quote the author: “If I had been told before that the whole database would be required in order to cover one position, I would laugh hard. But, the arising positions turned out to be so complicated and interesting! I am very happy with the result of this research as I believe I've done a great job and now the readers can be very confident about the opening outcome and the arising middlegame positions.”.

Meet 1.Nf3 with 1...d5 - Complete Repertoire against 2.b3, 2.c4, 2.g3

In his second database for Modern Chess, the Ukrainian FM with 2 IM norms and an experienced coach Yuriy Krykun analyses the pesky sidelines and interesting mainlines that arise after 1.Nf3 d5. He focuses on three continuations: 2.g3, 2.c4 and 2.b3. As Yuriy himself explains, “While for some players those move orders don't present much of a difficulty: say, most Slav players would meet 2.c4 with 2...c6, while QGD players will play 2...e6, it is a very important subject to cover. The reason is that for one, those move orders are often tried to get you out of book or move-order you in some line you might not want to play. Secondly, the suggestions presented here are universal and would suit you no matter what your main opening after 2.d4 is – whether it is the Slav, Queen's Gambit Declined, Queen's Gambit Accepted, or anything else. And, finally, it is always nice to have some variety as opposed to being forced to play what White wants: the Anti-Meran, the Anti-Queen's Gambit, etc”. The current database contains 11 theoretical chapters and 15 test positions that would check both your tactical and positional knowledge, as well as how carefully you have remembered some important opening ideas and move orders.

Play the Owen Defense against 1.c4

The Owen Defence is one of the most interesting and original among hyper-modern openings. It combines ideas from several different openings, such as the Queen's Indian, the Bogo-Indian, the Nimzo-Indian and the Dutch. Black completely refrains from occupying the centre with his pawns and controls it with his pieces from afar, frequently involving the f-pawn in the process. This database aims to offer a complete Owen repertoire against 1.c4 that avoids transpositions to the Queen's Indian or other main openings. The database consists of 24 theoretical chapters and 16 interactive test positions.

Play Queen's Gambit Declined against 1.d4 Nf6 2.c4 e6 3.Nf3 - Part 1

In the introduction to the current database, GM Eljanov writes: The Queen's Gambit Declined is truly a lifetime opening. Like no other it passed the test of centuries of chess practice. This opening was employed by almost all old maestros including Morphy, Chigorin and Steinitz as well as by modern super grandmasters like Carlsen, Ananda, Caruana and many others. Different move orders were popular at different times. If in the old days it was considered safe to allow the Carlsbad Variation after 1.d4 Nf6 2.c4 e6 3.Nc3 d5, nowadays most modern maestros tend to avoid typical Carlsbad pawn chains with Black and opt for 3...d5 only in response to 3.Nf3. Strangely enough, yours truly almost never played Queen's Gambit Declined with Black. Nevertheless, I suppose that it perfectly suits my style and chess philosophy. In this database, I decided to analyse Queen's Gambit Declined from Black's point of view and chose the most straightforward way to challenge the main move 5.Bf4 (after 1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 Be7 5.Bf4) with 6...c5!?. At some point, this move was a bit in the shadow of the solid 6...Nbd7 but recently it began to gain popularity again thanks to top GMs Nakamura, Caruana and Anand first of all.
