I'm building my White repertoire.
After 1. Nf3 d5 2. d4 Nf6 3. c4 e6 4. g3 Be7 5. Bg2 O-O 6. O-O dxc4 7. Ne5 c5 8. dxc5 Qc7 9. Nxc4 Rd8 we reach the following position:
[FEN "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1"]
1. Nf3 d5 2. d4 Nf6 3. c4 e6 4. g3 Be7 5. Bg2 O-O 6. O-O dxc4 7. Ne5 c5 8. dxc5 Qc7 9. Nxc4 Rd8
My question is: which move should I choose?
- Qc2
- Qb3
- Qa4
What are the advantages and disadvantages of each one of them?
I would like to choose the move which (on average) leads to the most positional, solid, quiet and strategic positions (not sharp and tactical positions).
There are only 6 games which reached this position in my opening database: White played 10. Qc2 in 3 of them, and White played 10. Qb3 in the other 3 of them.
