Grandmaster Ruslan Scherbakov examines an opening system for Black based on the Semi-Slav Triangle, an ambitious way to fight the ever-popular Queen's Gambit. Black's weapons include the Abrahams-Noteboom Variation - a dynamic counter-attack which takes White out of his comfort zone and offers Black the chance to dictate the game from the outset. Scherbakov also considers options for Black against the aggressive Semi-Slav Marshall Gambit, as well as White's quieter tries such as the Exchange Variation. Scherbakov has over 20 years' experience in studying and playing these opening variations, which have been tried and tested successfully at grandmaster level and are specially designed for players who want to challenge White in the opening. It is written by a renowned Semi-Slav Triangle expert. It is packed with new ideas and critical analysis. It explains typical plans and tactics for both sides.
