[January 22, 2017] Updated Opening Article by GM Slaviša Brenjo:
February 2014 Revisited: Ruy Lopez, Marshall Attack with 12. d3 (17. Nd2!?)

Our original main line of this variation stems from F. Caruana – L. Aronian, Zürich 2014, which has recently been improved upon: Black seems capable of equalizing if he follows the recipe from M. Nayhebaver – C. Repka, Banska Stiavnica 2016. The most recent top-level game in this line is P. Harikrishna – L. Aronian, Wijk aan Zee 2017.

[Diagram: Black to Move] The diagrammed position had originally appeared in M. Adams – L. Aronian, Tromsø (ol) 2014, and what followed was probably still a part of the Armenian grandmaster’s deep opening preparation. White was exerting pressure all over the board, so something had to be done about that. Can you follow in Aronian’s footsteps and maintain the balance as Black?

April 2014 Revisited: Chebanenko-Schallopp Slav (14. Ba5!)

After the original key game E. Bacrot – C. Balogh, Eppingen 2014 many good players have been introducing their attempts at improvements for both sides, so we have decided to update this article with recent developments in this line. The most recent game in this line is W. So – M. Carlsen, Wijk aan Zee 2017, where Black equalized effortlessly.

[Diagram: White to Move] White had major difficulties defending his pieces and pawns in D. Bocharov – D. Andreikin, Sochi (rapid) 2016, so passive approach might not have been the best approach for him. Any ideas on how to proceed as White in the diagrammed position?

[January 8, 2017] Trusted: Opening Survey by GM Slaviša Brenjo
Ruy Lopez, Berlin Defense with 6… d5!? (9. Nbd2)

Playing an early d5 in the Open Games has become something of a trend at the highest level: that central response against the Italian Game is now a dominant choice of the players of Black, and it’s also gaining traction in the Berlin Defense, where it has to be followed by the recapture on d5 with the queen instead of the knight.

In addition to two high-profile games (A. Grischuk – P. Eljanov, Novi Sad 2016 and F. Caruana – W. So, London 2016) our examination of this approach will also include a number of engine games played in the past 2-3 years, which will surely broaden our understanding of this soon-to-be-fashionable line.

[Diagram: Black to Move] Black’s lack of piece coordination and his awkwardly placed Knight on h3 require immediate attention, or White will play Nc5 with devastating consequences. Any ideas?

May 2015 Revisited: Trompowsky Attack with 2… Ne4 3. h4 c5 4. dxc5 Qa5+  

This update is a small tribute to our late colleague GM Dragan Paunović. In memory of our dear friend, our Editorial Board will keep updating his lines and articles.

From Hodgson to Rapport, the Trompowsky Attack has been a source of inspiration for creative chess minds. This update continues to showcase some, often borderline extravagant, but always innovative ideas for both sides, including the input from our trusty silicon friends.

[Diagram: White to Move] Black has stopped the first wave of White’s attack and is now ready to chase away his opponent’s pieces and seize the initiative. How can White rekindle his attack and create good practical chances?

After the original key game W. So – H. Nakamura, Saint Louis 2016 many good players had followed suit, so we have decided to update the article with recent developments in this line.

[Diagram: Black to Move] Black had major difficulties defending his pawns in E. Iturrizaga Bonelli – J. Schroeder, London 2016, so passive approach might not have been the best approach for him. Any ideas on how to proceed as Black?
