So Black needs to be prepared for this if he wants to play the Zindzi-Indian Defense. MB}] 4...Bxc3+ 5.bxc3 The Zindzi-Indian Defense, named after its inventor, GM Roman Zindzichashvili. He first played it against Dmitry Gurevich at the 1984 US Championship in Berkeley, CA and obtained a draw. Black has traded his valuable fianchettoed bishop to destroy the White queenside pawn structure. Black's hope is that he can keep the game closed and that the Black knights will prove to be better pieces than the White bishops in this strange pawn structure . Incidently, there are 254 games with this position in the Chessbase Mega 2000 database. MB}
