I was just wondering, in the Queen's Gambit Declined, after 1. d4 d5 2. c4 e6 (or 2... c6), what is the difference between playing 3. Nc3 and 3. Nf3 ?
I looked in an opening database/explorer :
- After 2... e6, 3. Nc3 is 3 times more popular than 3. Nf3, but 3. Nf3 scores better for white (+43.6% -22.4% for 3. Nf3, versus +42.6% -26.1% for specific variations? If yes, what are those variations?
Thanks in advance for your answers.
I am not an expert on the QGD and here on RHP I just use the books to get me to a reasonable middlegame. It appears to me that the original QGD was normally played with the moves:
1.d4 d5 2.c5 e6 3.Nc3 Nf6 4.Bg5
Because 4.Nf3 was considered less aggressive in putting pressure on Black's center.
I think some masters don't like how things turn out after Black is allowed to pin the Knight at c3 with 3...Bb4, so they play 3.Nf3 which delays the pin move and also allows them to switch into the Catalan Opening System with 4.g3 if they choose.
This may be completely wrong for it is just my opinion.
In the Slave Defense variation of the QGD the move 3.Nf3 allows White to switch over to the London System with 4.Bf4 if he chooses.
I am only a class C player OTB, which is far from being an expert or master, so what I think may be wrong. Maybe greenpawn34 the real expert instructor for this Chess Forum will step in and explain it to you.
