Lilienthal variation D44 Botvinnik variation 11. g3 · Lilienthal variation White prepares to fianchetto the light-squared bishop. Blacks main response is /11...Bb7/, fighting for the a8-h1 diagonal. /11...Rg8/ is a sideline, preparing to exchange the rook for White's powerful dark-squared bishop. White ends up having a rook, a pawn and open lines on the kingside for the two pieces. History This move made its debut in 1944, in a game between Andre Lilienthal (whom the opening is named after) and Mikhail Botvinnik.https://www.chessgames.com/perl/chessgame?gid=1032094 Theory table all 11. ...
