“Queens gambit declined knight defense” refers to a QGD line where Black meets the queen’s gambit with a knight setup rather than immediate central counterplay.

Conversely, if you’re Black, use the knight’s placement to time …c5 breaks or …Bb4 pinning ideas—these are the practical ways the “knight defense” concept shows up beyond the first few moves.
