7. N1c3
7. N1c3 defends White's e4 pawn while developing their knight.
Black usually continues 7...a6, compelling White to retreat to the passive a6 square. However, at least from there White will overprotect the c4 pawn and keep d5 in sight of their queen.
Black can delay a6 until after they have castled: 7...Be7 8. Be2 9. O-O O-O 10. a6.
