4. e4
[edit | edit source]The most principled move, with 4. e4, White takes over the centre that Black has conceded.
Black's main move is 4...d6. The d-pawn prevents White from playing 5. e5 and kicking Black's knight, opens a line for the queen's bishop, and will be a springboard for later attacks on the centre, ...e5 or ...c5. White has a variety of responses: the mainline is 5. Nf3 O-O 6. Be2 e5 7. O-O.
4...O-O is also playable as, if 5. e5, Black can save the knight on the newly-available e8 square (5...Nh5?? 6. g4 traps the knight) and the game may continue 5...Ne8 6. f4 d6 7. Nf3. More commonly however White plays 5. Nf3 and after 5...d6 the game transposes.
4...d5? now loses a pawn, as White's c and e pawns clamp down on d5. If Black had been planning to play a Grünfeld, then they have missed their chance.
