Taking on c4 is best after white has moved his light bishop to not give him a tempo when he does Bxc4
When to take on C4 in QGD?? (Reply here)


LMAO U can perfectly take the c4-pawn almost any time (whenever U want) and QGD will become (delayed) QGA. U have misunderstood the Wikipedia.
For the Queen's Gambit,

might serve as a general introduction. We have often seen recommendation of the somewhat older book, Queen's Gambit Declined by Matthew Sadler (2000).

Perhap it would help to make an explicit choice of a QGD possibility favored by Lasker, Chigorin, Tarrasch, Tartakower, or Capablanca.

For reasons below I agree I misread the wiki. But you should know that the based on my topic titles that I wasn't even talking about a QGA in the first place.... I am talking about when to take on C4 in the QGD not an immediate dcx4.....
Here is the exact wiki quote ''In its broadest sense, the Queen's Gambit Declined is any variation of the Queen's Gambit in which Black does not play ...dxc4. Variations other than the Orthodox Line have their own names and are usually treated separately'' (QGA)

In two classic variations, Black plays dxc4 as part of a set of freeing exchanges
Laskers Defense
And Capablanca's freeing maneuver
Thanks and sg_1999 as well. I have the C5 to strike back at the center. It wasn't a Tarrasch defense because it was a well into a few moves in the QGD. Is this reasonable?

I seen master games when black takes the dxe4 after a few moves in the QGD. But I also read that black shouldn't take c4 pawn at any time in the QGD (Wikipedia)
Am I confusing something?
