Hello.
A week ago I asked a question about the difference between 3. Nf3 and 3. Nc3 in the Queen's Gambit Declined. And today, after another week of exploration of the Queen's Gambit, I have another question. This time, it's regarding the Queen's Gambit Accepted : 1. d4 d5 2. c4 dxc4.
What is the difference between playing 3. Nf3 and 3. e3 ?
But this time I've made some searchs on my own, I've looked in an opening database/explorer, and here's what I found.
Firstly, 3. Nf3 is three times more popular than 3. e3.
But, 3. e3 scores much better for white than 3. Nf3 :
- With 3. Nf3, white won 38.5% of the time and lost 24.2% of the time
- With 3. e3, white won 41.9% of the time and lost 21.9% of the time.
A big difference.
Also, here is what black plays against 3. Nf3 :
3... Nf6 : 67%
3... a6 : 15%
3... c5 : 7%
3... e6 : 5%
And here is what black plays against 3. e3 :
3... Nf6 : 51%
3... e5 : 18%
3... e6 : 14%
3... c5 : 6%
So it seems that 3. e3 allows black to play 3... e5 instead of 3... Nf6 (in the 3. e3 line, if you add up the 51% of 3... Nf6 and the 18% of 3... e5, you get 69%, which is very close to the 67% of 3... Nf6 in the 3. Nf3 line).
When I found out this, I thought 3. Nf3 was simply better.
But, after looking more closely, I saw that after 3. e3 Nf6 4. Bxc4, black plays this :
4... e6 : 84%
4... a6 : 5%
While after 3. Nf3 Nf6 4. e3, black plays this :
4... e6 : 65%
4... Bg4 : 19%
(again, if you add up the 65% and the 19%, you get 84% )
So it seems that 3. Nf3 allows black to play this 4... Bg4 move.
While after 3. e3 Nf6 4. Bxc4 a6 5. Nf3 black can't play 5... Bg4?? because of the tactical shot 6. Bxf7+ Kxf7 7. Ne5+ Ke8 8. Nxg4.
So, if what I found out is correct, it seems that I should just play 3. Nf3 if I want to avoid 3... e5, or play 3. e3 if I want to avoid 4... Bg4.
But I have still no idea which of those two move to choose... Should I just go with 3. e3 simply because white strangely scores much better with it than with 3. Nf3 ? And do each of those two moves allow white to avoid other things that I didn't see?
Thanks in advance for your answers.
