The Berlin Defence, 3...Nf6, has long had a reputation for solidity and drawishness and is commonly referred to as "the Berlin Wall". The Berlin Defence was played in the late 19th century and early 20th century by Emanuel Lasker and others, who typically answered 4.0-0 with 4...d6 in the style of the Steinitz Defence. This approach ultimately fell out of favour, as had the old form of the Steinitz, due to its passivity, and the entire variation became rare. Arthur Bisguier played the Berlin for decades, but always chose the variation 4.0-0 Nxe4. Ever since Vladimir Kramnik successfully used the line as a drawing weapon against Garry Kasparov in their 2000 World Chess Championship match, the Berlin has experienced a remarkable renaissance: even players with a dynamic style such as Alexei Shirov, Veselin Topalov, Hikaru Nakamura, and Kasparov himself have tried it, and Magnus Carlsen and Viswanathan Anand both used it (Carlsen extensively so) during the 2013 World Chess Championship and 2014 World Chess Championship. Today this variation is the most common opening after 1.e4 e5 and almost all the top players regularly play it.

Since Black's third move does not threaten to win the e-pawn—if Black captures it, White will win back the pawn on e5—White usually castles. After 4.0-0, Black can play either the solid 4...Nxe4 (the Berlin Main Variation) or the more combative 4...Bc5 (the Berlin Classical Variation). After 4...Nxe4 5.d4 Nd6 (5...Be7 is the Rio de Janeiro Variation) 6.Bxc6 dxc6 7.dxe5 Nf5 8.Qxd8+ Kxd8 (l'Hermet Variation), White is considered to have a small advantage from a somewhat better pawn structure and Black's awkwardly placed king. Black, by way of compensation, possesses the bishop pair and has no positional weaknesses, so it is difficult for White to exploit the structural superiority without opening the game for Black's bishops; all four of the games in the Kasparov–Kramnik match in which this line was employed ended in draws. An alternative for Black, though seldom seen since the 1890s, is 6...bxc6 7.dxe5 Nb7, although White keeps an advantage despite Black's two bishops, as it is difficult for him to gain active counterplay. However, despite its drawish tendency, the Berlin Endgame remains the sternest test of the entire variation beginning with 3...Nf6, and a lot of theory has evolved here. Today's consensus is that Black will hold with accurate play in the Berlin Endgame, so players have moved on to the lines with 4.0-0 Nxe4 5.Re1, the modern main line, considered to be White's best try for an opening advantage, and advocated by Fabiano Caruana in his Chessbase Series on the Ruy Lopez opening.

White's move 4.Nc3 transposes to the Four Knights Game, Spanish Variation.

Blitz chess (also known as speed or fast chess) is a type of chess in which each player is given less time to consider their moves than normal tournament time controls allow. Openings, tactics and strategy are same.
