The Steinitz Defense Deferred

The Steinitz Defence Deferred is an interesting and still relatively unexplored system against the Ruy Lopez (3.Bb5). Apparently passive, yet extremely solid and quite flexible, it has survived the test of time since the late 19th century. Chess greats like Janowski, Schlechter, Capablanca, Alekhine, Keres, Smyslov, etc. The aim of this opening survey is to provide you with an easily understandable and concrete Steinitz Defence Deferred (in further text SDD) opening repertoire against the Ruy Lopez. SDD is a relatively rare occurence on the top level, but this can be a blessing in disguise for a club or a casual tournament player. Many white players dismiss such opening variations as second-rate and pay less attention to them than to Breyers and Marshalls of the world, on which they are ready to spend countless hours of analysis. If your knowledge of SDD is solid and deep, while your opponent's is superficial and coupled with "today I play against that off-beat Ruy Lopez line" approach, guess who has the upper hand?

Positional Repertoire against the French

French Defence is a tough nut to crack. This opening has a reputation for being a very good counter-attacking weapon. It was used with success by almost all the great players at the past and nowadays. Since the arising middlegames are extremely complex, usually, all three results are possible. Above-mentioned considerations explain why the choice of weapon against the French Defence is so important when we play 1.e4. In the current database, IM Renier Castellanos suggests a positional repertoire against the French which is based on the so-called Tarrasch Variation.

Classical Repertoire Against Bogo - Indian Defence

The Bogo - Indian Defence is one of the most topical opening after 1.d4. Every 1.d4 player should be very well prepared against it. White has several ways to meеt 3...Bb4+, but 4.Bd2 - is the most natural option, which would be the topic of the current survey. White is not aiming to get the pair of bishops but is continuing the normal development, counting on his space advantage in the center. What I like about the line 4.Bd2 is that White's play is natural and positionally sound. It's true that often White's advantage will be marginal. However, I strongly believe that when your opening is based on a good positional ground, it's easier, at least from a practical point of view, to handle the position in the middle game as well
