[edit] 2. c4

2.c4 strengthens White's control of the center, particularly the important d5 square. It also allows White's queenside knight to develop to the active c3 square without blocking the c-pawn.

Black has a number of possibilities at this point:

• 2...e6 - This move is solid and flexible. Depending on how white plays, black will end up in a Queen's Indian, Nimzo-Indian, Bogo-Indian, Queen's Gambit Declined, or a Benoni.
• 2...g6 - This tends to be more aggressive (and riskier), though still solid if one knows the important strategic points. Black has the choice to move into a King's Indian Defence (KID) (regardless of white's play) or possibly a Grünfeld if white plays 3. Nc3 and black wishes.
• 2...c5 - This will likely end up being a Benoni (often aggressive, risky), Benko-gambit( positional pawn sacrifice by black on queenside), a symmetrical English (a bit quieter, but active pieces), or even a Tarrasch QGD (active for both sides).
• 2...d6 - This is the so-called "Old Indian," and it can either transpose into a KID or follow less popular lines with a strategy similar to the KID.
• 2...e5 - The Budapest Gambit. It has a unique character and often allows black active play. White usually gives the pawn back eventually, and usually gets a slightly better position, but black can do well against the ignorant white player.
• 2...d5 - The Marshall Defence. This is not the best idea, though not an absolute trap. Several opening encyclopedias give this a clear advantage to white if played right.
