Default Re QGD what is wrong with 3. c5?


My opinion on 3. c4-c5 is that:

a) Violates the GENERAL PRINCIPLE of moving the same piece (or pawn) twice
instead of rapid development of your pieces.

b) One idea of the Queen's Gambit is for Black to play 2...d5xc4 (accepting
the gambit) so that White can get a slightly longer lead in development and
space via 3. e2-e4 giving White the classic center. In most lines White will
evenually win the pawn back.

c) By playing 3. c4-c5 you allow Black to play 3...e7-e5 4. e2-e3

(if 4. d4xe5 Bf8xc5 5. Nc1-c3 Ng8-e7
( if 5 ...d5-d4 6. Nc3-e4 f7-f6 7. Ne4xc5 Qd8-a5+ 8. Qd1-d2 Qa5xc5 9. e5xf6
Ng1xf6 and White maintains his slight advantage mainly due to Black's weak
d4-pawn.)
6. Ng1-f3 0-0 and Black gains the 'first move' tempo that White had.)

....Nb8-d7 5. Nb1-c3 Bf8-e7 and Black gains the 'first move' tempo that
White had.

d) After White plays 3. c4-c5 Black can elect to develop his pieces
normally and keep the position closed (on the queenside) and expand on the
kingside where he can contend with White on almost equal terms.

These things may not mean much to White at the club level and he may be able
to contend, but a strong Black player can exploit 3. c4-c5 with advantage.
