This robust, multipurpose opening system (in which Black plays d6, Nf6, Nbd7 and e5) looks quiet, like a sleeping lion - hence the name. But when this predator is provoked, and the game heats up, Black eats its prey in an extremely swift and efficient way. The story of The Black Lion is remarkable: Jerry van Rekom and Leo Jansen are two strong Dutch club players who developed the system and wrote a book about it in 1997. Their work attracted a lot of attention and had to be reprinted many times. This is a fully revised and updated edition. Further information about the book is available at newinchess.com
