Put up a puzzle of it so we can see it better.
Tarrasch Defense?

Mikhail Tal played the Tarrasch Defense quite successfully. He liked the moves ...1.Nf6 and ...2.e6. That way he could switch in and out of the Modern Benoni, Nimzo-Indian or the Queens' Gambit Declined.
Black will play with an isolated queen pawn in this defense.

The Tarrasch is a fine defense just know the IQP positions. If you want to mix it up use the Henning-Schaara variation of the Tarrasch. Not for the faint of heart.
this occurs after 1 d4 d5 2 c4 e6 3 Nc3 3 c5 4 cxd5 exd5.
What do you think about it? I haven't played it yet but it looks interesting because white has the option of giving black an isolated d pawn but it does a good job of controlling the center and preventing e4. So with a better center, wouldn't this give black dynamic chances?
