3...Be7 · Charousek variation
[edit | edit source]Black stops White from playing the immediate 4. Bg5, practically forcing White into one of three options:
4. Nf3, simply developing the knight. This is the most common and flexible response, since White doesn't reveal anything about their setup yet. If Black plays 4...Nf6 then 5. Bg5 transposes back into the main lines.
4. Bf4 develops the bishop to f4 instead. White intends to enter the Harrwitz attack.
4. cxd5 transposes into an exchange variation where Black has already played Be7, preventing White from usefully developing the bishop to g5.
