I've been playing c5 as black in Queens Gambit Declined lately.


[FEN ""]
1. d4 d5 2. c4 e6 3. Nf3 Nf6 4. e3 c5

I just want to know, how bad an idea it is to play in this way? I saw someone play it in bullet game but I don't know when it's best to play.

  • Have a look at the moves again. 4. Bd3 isn't possible in that move order. Commented May 24, 2017 at 19:26
  • @DagOskarMadsen That's true😄

  • Kf6 Kf3? U wot? Also, why are you asking how bad it is? You should be asking how good it is. Commented May 24, 2017 at 19:53
  • 4.e3 is very rare move and intuitively it can be changed by 4...c5. After 4...c6!? 5.Nbd2 c5! is the main line, even though it is often reached via Slav move order. Here you are tempo up, on the other hand white knight can go to c3. I don't think this option is so great for white that it is worth more than one move.

  • Evaluation is +0.2, seems like an OK move. Commented Jul 9 at 0:20

The move 4... c5 is good because:

  • It is thematic in the Queen's Gambit Declined to break with either ...c5 or ...e5. With 4...c5, this is done without loss of time
  • White isn't putting pressure on the centre, so Black can take it

Here is a sample game, which ended in a draw, between top players Karpov-Sveshnikov

[FEN ""]
[White "Karpov"]
[Black "Sveshnikov"]
