Dealing with Colle, London and Barry after 1.d4 Nf6 2.Nf3 d5: Repertoire Preparation

I would love to play Benko Gambit after 1.d4 Nf6 2.c4, but White does not play 2.c4 always. He often opts for 2.Nf3. I am thinking of replying 2.d5 and deal with the openings that arise from there.

This of course includes a large number of annoying openings such as Colle, London, Torre, Veresov. Against all of them, I intend to play ...g6, ...c5, ..Nc6, ..Qb6 and equalize.

Game 1: Bareev - Judit Polgar

Game 2: Minzer - Dreev

Game 3: Juegel - Horvath

Game 4: Zichichi - Lalic

Game 5: Hebden - Palliser
