Opening Library
Every opening worth knowing — from the Italian Game and Caro-Kann to the Stafford Gambit and the Grob. Each one has its own page with video lessons, key ideas, and common mistakes.
Benoni Defense
1.d4 Nf6 2.c4 c5 3.d5 e6 — asymmetric structure, dynamic play, kingside fianchetto, queenside counterplay.
Berlin Defense
Ruy Lopez with 3...Nf6 — the famous "Berlin Wall" used by Kramnik to neutralize Kasparov. Leads to a tough, slightly drawish endgame.
Bogo-Indian Defense
1.d4 Nf6 2.c4 e6 3.Nf3 Bb4+ — Nimzo-Indian style pin against the white knight on f3. Solid and flexible.
Catalan Opening
The Catalan combines a Queen's Gambit setup with a fianchetto bishop on g2. Long-term pressure, technical positions, world championship favorite.
Dragon Sicilian
Sharp Sicilian variation: Black fianchettoes the king's bishop on g7 and attacks the queenside while White attacks the kingside in opposite-side castling battles.
Grünfeld Defense
1.d4 Nf6 2.c4 g6 3.Nc3 d5 — let White build the giant center, then dismantle it with piece pressure.
Jaenisch Gambit
Ruy Lopez with 3...f5!? — Black sacrifices a pawn for sharp counterplay and an open f-file.
King's Indian Defense
1.d4 Nf6 2.c4 g6 — let White build the center, then attack it with ...e5 or ...c5. Hypermodern, double-edged, beloved by attacking players.
Latvian Gambit
1.e4 e5 2.Nf3 f5!? — the King's Gambit reversed. Wildly aggressive but objectively bad.
Najdorf Sicilian
The most respected Sicilian variation: 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6. Played by Fischer and Kasparov. Massive theory, flexible plans.
Nimzo-Indian Defense
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 — pin the knight, ruin White's pawn structure, play strategically. The most respected defense to 1.d4.
Queen's Indian Defense
1.d4 Nf6 2.c4 e6 3.Nf3 b6 — fianchetto the queen's bishop and contest the long diagonal. Solid, drawish, classical.
Reti Opening
1.Nf3 with a flexible kingside fianchetto. Hypermodern attack on the center from the flanks.
Scheveningen Sicilian
The "small center" Sicilian: Black plays ...e6 and ...d6 with flexible piece development. Often reached via Najdorf move orders.
Semi-Slav Defense
1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.Nf3 e6 — the fighting Slav. Combines solid structure with sharp counterplay (Meran, Botvinnik, Anti-Meran).
Sicilian Defense
1.e4 c5 — the most popular and combative response to 1.e4. Black fights for d4 and creates an asymmetric battle. Favored by Kasparov, Carlsen, and most attacking players.
Traxler Counterattack
After 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 — Black plays 4...Bc5!? sacrificing material for a vicious attack on f2.
