The Petroff Defense is a chess opening played by Black, and it is named after the Russian master Alexander Petroff who popularized it in the 19th century. The Petroff Defense is a solid and conservative defense to 1.e4, and it has been used successfully by many top Grandmasters, including Garry Kasparov, Vladimir Kramnik, and Dmitry Jakovenko.
The Petroff Defense begins with the moves 1.e4 e5 2.Nf3 Nf6, and it aims to create a solid pawn structure with the pawns on e5 and d6, while simultaneously controlling the center with the knight on f6. Black’s pieces are well-positioned to challenge White’s center pawns and create counterplay against White’s light-squared bishop.
One of the key ideas behind the Petroff Defense is that it aims to draw the game, as Black does not have many active pieces and does not have many pawn breaks. However, Black can create counterplay by exchanging pieces and creating tactical opportunities, especially if White misplays the opening.

Another line of the Petroff Defense is 3.d4 Nxe4 4.Qd3, which aims to challenge Black’s knight on e4 and create tactical opportunities. Black can either capture the knight with 4…Nxf2, which leads to a sharp and tactical position, or capture the queen with 4…d5, which leads to a symmetrical pawn structure.
The Petroff Defense can also be met with 3.Bd3, which aims to support the pawn on d4 and challenge Black’s knight on e4.
