The Benoni Defence is a very double-edged weapon, well suited to play for a win but also dangerous. On his recently released DVD, Rustam Kasimdzhanov, one of the world's most renowned opening experts and one of the second former World Championship Challenger Fabiano Caruana, claims that "The Benoni is back in business". IM Roven Vogel took a close look at Kasimdzhanov's latest DVD to check this claim. This could be a perfect DVD to increase one's arsenal of openings and enrich themselves in these difficult times. The DVD has almost six hours of content including exercises, multiple lines and also a video on how to avoid Benoni. Photo: ChessBase

Roven Vogel won the World Youth under-16 Championship in 2015. At the beginning of this year, he qualified for the next Tata Steel Challengers Tournament in Wijk aan Zee, Netherlands by winning the Qualifiers in Wijk. To get a better understanding of how the best players study and work, he took a close look at Caruana's DVDs about the Ruy Lopez which he considers to be entertaining and helpful for chess players of all levels. What better way to delve into Caruana's mind before the Candidates, than by studying about Ruy Lopez, straight from the former World Championship Challenger's voice and analysis. Photo: ChessBase
