Romanishin Variation against the Nimzo-Indian - Repertoire for White

The so-called Romanishin Variation is getting very popular recently. White goes for a flexible setup with the idea to build a long-term positional pressure. The fact that Black has plenty of ways to meet the Romanishin Variation makes its preparation arduous. Black’s available lines are fluctuating from solid equalizing attempts to highly complex and risky tries. As we can see Black faces an annoying dilemma, playing solid aiming for equality would mean in practice being under pressure for several moves. On the other hand, the interesting unbalanced lines tend to be risky. This line was first played by Akiba Rubinstein, later by Alekhine and much later in the 70s Oleg Romanishin used it extensively and with success, but perhaps the most important milestone for the variation came in 1985 when Kasparov used it successfully to beat Karpov. Nowadays, it is employed by the World’s best players occasionally.

Complete Najdorf Repertoire for Black - Part 2

In Part 1, IM Renato Quintillano wrote a quick summary of Black's main ideas and goals in the Najdorf, explaining the reasons why he thinks it is the most reliable option for Black in the Sicilian. In that database, he dealt with the positional lines, in which White wants to keep the position under control and prevent Black from taking the initiative, playing for a small advantage and a strategic approach. Time has come now to deal with those uncompromising lines, in which White seeks a direct attack against the black king, initiating a bloody battle for the initiative. Here the game tends to develop in a very concrete way, and both sides need to search for tactical resources and attacking ideas, instead of strategic motifs and positional maneuvers, as in the first database. Some move orders and subtleties gain in importance now, and strong calculation skills are required.

1.d4 Nf6 2.c4 e6 3.Nf3 d5 - Ragozin and Queen's Gambit with 4...a6 for Black

In the second installment of 'Repertoire for Black against 1.d4', GM Kuljasevic suggests an opening repertoire against 3.Nf3 based on the Ragozin Defense (4...Bb4) and Modern Queen's Gambit (4...a6). Similarly to the Repertoire against the Catalan, the idea is to have one equalizing opening system that you would be comfortable playing against strong opponents, as well as one sharp system that you would use to imbalance the game, get your opponent out of his comfort zone, or just get a playable game without much opening theory, hoping to outplay him in the long run. In this database, the Ragozin Defense will have the role of a solid equalizing weapon, while the Modern Queen's Gambit will be the sharp one.

Complete Najdorf Repertoire for Black - Part 1

The Najdorf is the most popular Sicilian played in tournaments, and our author IM Renato Quintiliano considers it the most reliable option in the Sicilian universe. It promises an active game for Black and real chances of playing for a win. The main practical problem for Black, however, is that White has a really wide range of options to face the Najdorf. White can even avoid an open and sharp battle for the initiative and instead go for more solid and positional lines, which can prove a problem for aggressive Black players. It means that if you want to develop a deep knowledge about the Sicilian Najdorf, in order to use this opening as a weapon in your repertoire, it is necessary to not only be aware of long and sharp theoretical lines, but also of positional ideas, typical maneuvres and structures, developing a good strategic understanding about them. These positional lines will be the subject of our first (of three) databases dedicated to the Sicilian Najdorf.
