GM Michael Roiz keeps building his 1.e4 e5 repertoire with another fascinating work - Expert Repertoire against the Scotch Game. The Scotch Game has always been considered a challenging and ambitious antidote to 1...e5. If you are an 1...e5 player, you should take this opening very seriously.
In this database, GM Michael Roiz provides an expert solution for Black based on 1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Nf6
The move 4...Nf6 has always been considered Black's most ambitious system against the Scotch Game. White should immediately decide how to deal with the defence of the e4-pawn. Objectively speaking, 4...Nf6 is Black's only way to completely solve the problems. Therefore, it's not a surprise that this is the top choice of the elite players.

We are pleased to present another fascinating opening survey by GM Davorin Kuljasevic - Play the Neo-Seirawan System against King's Indian Defence.
The starting position of the repertoire arises after 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Bd3
In the introduction to the database, the author writes, "At first, this seems like a mixup between the two different systems. Usually, we develop our bishop and knight either in the ''classical'' Be2-Nf3 or the ''Seirawan'' Bd3-Ne2 formation. By comparison, Bd3-Nf3 (which I decided to name the ''Neo-Seirawan'' variation) seems less principled because it allows Black to pin the knight with Bg4. However, things are not that simple for Black after this move, as we will see.

This is one of the most thorough courses on the Alekhine Defence that you will ever see. This database provides something more that usual opening repertoire.
In the introduction, Marin writes, "This time I adopted a different approach than in all my previous courses published by Modern Chess. Usually, I examine one line against all the opponent's systems. This time, I have analyzed two or more alternatives for Black, whenever the case was given (not in the minor lines, though). I had two main reasons for that. First of all, the way I built this database can offer a reliable repertoire for a long time."
