Are you struggling to play against London, Jobava London, Colle systems? Ten years after I published "Beating 1.d4 sidelines" I am presenting my new file with extensive coverage of White major sidelines after 1.d4 d5. You will find Black powerful solutions against London, Jobava London, Colle Zukerort, Blackmar -Diemer Gambit and all other major variations White can offer. My file contains 376 novelties/improvements! As always I truly believe it will set you up for many years ahead playing against these variations.
