The Caro-Kann Defence, long renowned for being a solid and reliable defence against 1.e4, is undergoing a renaissance at the moment. In addition to being a mainstay in the repertoires of a recent World Champion (Viswanathan Anand) and a 2018 World Championship candidate (Ding Liren), it is being flooded with new and creative ideas from a range of other top players, notably Anand’s Indian Olympiad teammates Vidit and Adhiban. The pawn structures in this opening leave considerable room for individual interpretation.
