The Improved Tarrasch Defense is a closed game and is a sub-variant of the Queen's Gambit . It develops from the rejected Queen's Gambit .

Each of its main variants begins with the following moves:

1. d2-d4 d7-d5 2. c2-c4 e7-e6 3. Nb1-c3 Ng8-f6 4. Ng1-f3 c7-c5

Unlike in the normal Tarrasch defense , Black can avoid his Isolani here after 5. c4xd5 by Nf6xd5 . That counts as an improvement.

Now 6. e2 – e4 Nd5xc3 7. b2xc3 with White overweight in the center is the most concise continuation.
