The most common fourth move for White, which leads into the main lines of the Berlin, is 4. 0–0. The typical continuation is ...Nxe4 5. d4 Nd6 6. Bxc6 dxc6 7. dxe5 Nf5 8. Qxd8+ Kxd8 (sometimes called the l'Hermet variation), which was played in all four Berlin games of the Classical World Chess Championship 2000. The queens are exchanged off the board early, leading to a position that is difficult for White to win. Vladimir Kramnik assesses the endgame as better for white, but believes that this advantage is usually insufficient to win and that Black should be able to draw. Black's alternatives are generally regarded as inferior, such as 4...d6 which is considered too passive, and 4...Bc5 which allows white to play 5.Nxe5 (preparing to respond to 5...Nxe5 with 6.d4) or 5.c3.
