White repertoire

Italian Game

The Italian Game is one of the oldest classical openings for White. With Bc4, White takes aim at Black's weak f7 pawn. In most variations, White has options to dictate the pace of the game, making the Italian a flexible weapon.

London

The London System is an opening system that has gained enormous popularity in recent years for its simplicity and consistency. The London piece setup is naturally well-suited for a kingside attack, with the light-squared bishop aimed at h7 and both knights ready to hop into action on the kingside.

Queen's Gambit Declined

The Queen's Gambit Declined is one of the most common ways for Black to decline the Queen's Gambit, reinforcing the d-pawn in the process. It includes a wide range of solid, deeply analyzed variations.

Scotch Game

The Scotch Game occurs when White breaks in the center with 3.d4, immediately opening the position. Black can equalize with accurate play, but the Scotch offers practical opportunities for active and tactical play.

Black repertoire

Caro-Kann

The Caro-Kann Defense is one of the most positionally sound replies to 1.e4. Black prepares to contest White's center with ...d5 and builds a solid pawn structure that is difficult to attack.

French Defense

The French Defense is a solid response to 1.e4. Like the Caro-Kann, Black prepares ...d5 to contest White's center, while retaining strong counterattacking chances.

Sicilian Defense

The Sicilian Defense gives Black strong counterattacking chances against 1.e4. It is an intensely theoretical opening with many sub-variations for both White and Black.

1 chapter · 38 positions

King's Indian Defense

The King's Indian Defense is a popular system where Black prioritizes kingside development. Although the setup is flexible, Black must know concrete middlegame ideas to meet White's many possible replies.
