4. cxd5
[edit | edit source]Black is down a pawn.
4...Qxd5!?, retaking immediately, has been played but concedes the initiative back to White. 5. Nc3 develops with tempo and the line continues 5...Qd8 6. d4 e6 7. Nf3 Nf6 8. Bd3 Be7 9. O-O O-O⩲.
4...Nf6 is the main move. This prepares to recapture the d-pawn with the knight. White either concedes the pawn back straight away, 5. Nc3 Nxd5, or attempts to hold onto it with the intermezzo 5. Bb5+!?, intending 5...Bd7 6. Bc4. This brings a defender to the pawn while also cutting the number of attackers (Black's bishop on d7 prevents their queen from seeing d5). Better for Black is 5...Nbd7, which can answer 6. Bc4 with 6...Nb6!.
The line after 5...Nbd7 continues 6. Nc3 (defending the pawn) a6 7. Qa4 (x-rays the rook) Rb8 8. Bxd7+ Qxd7 9. Qxd7+ Bxd7=: because the pawn is isolated and White cannot defend it with another pawn, Black can eventually pick it back up, e.g. ...Bf5 and ...Re1.
