Your Sicilian doesn't have to be a personality flaw.
KGA: Bishop's Gambit
CommunityAn aggressive King's Gambit Accepted weapon — sac the f-pawn, develop Bc4, and play for a kingside crush. Deep coverage of 3…Qh4+ plus answers to 3…d5, 3…Nf6, 3…g5, 3…c6, 3…Ne7 and 3…b5.
The London System
OfficialA rock-solid d4 + Bf4 system you can play on autopilot against almost anything. Bf4, e3, c3, Bd3, Nbd2 — then strike with Ne5 and a kingside attack. 50 lines.
Caro-Kann Defense
OfficialA Caro-Kann built around the c-pawn breaks — Black's freeing ...c5 in the Advance, and the Panov-Botvinnik c4/c5 structures. Solid, with active piece play. 18 lines.
King's Indian Defense
OfficialHand over the center, then blow it up. The KID is the ultimate fighting answer to 1.d4 — Classical, Sämisch, Four Pawns, Averbakh, and Fianchetto. 50 lines.
Italian Game
OfficialThe classical 3.Bc4 — fast development, pressure on f7, and the c3+d4 center. Covers the Giuoco Piano, the Two Knights, and Black's sidesteps.
King's Gambit
OfficialThe romantic gambit, played properly: 2.f4 and 3.Nf3. The Kieseritzky (3...g5 4.h4 g4 5.Ne5) carries the main weight, with the Modern 3...d5, the Cunningham, the Falkbeer, and every declined system covered.
Ruy Lopez
OfficialThe Spanish torture: 3.Bb5 and long-term pressure on e5. Main-line Morphy structures plus the Berlin, the Exchange, and Black's early deviations.
Queen's Gambit
Official2.c4 against everything — punish the Accepted, squeeze the Declined, meet the Slav head-on. The backbone of 1.d4 chess.
Vienna Game
Official2.Nc3 keeps every option open — then f4 hits like a delayed King's Gambit. The Vienna Gambit against ...Nf6 and Bc4 pressure against ...Nc6.
Scotch Game
Official3.d4 blows the center open on move three. Forcing, theory-light, and full of open lines — Kasparov's surprise weapon turned club favorite.
Sicilian Najdorf
OfficialThe sharpest scoring weapon in chess: ...c5, ...d6, ...a6 and a fight in every line. English Attack, Bg5, Be2, Bc4 — the big White tries, met head-on.
Sicilian Dragon
OfficialThe g7 bishop breathes fire down the long diagonal. Yugoslav Attack mains with ...Rc8 and ...d5 breaks, plus the Classical and every sideline.
French Defense
Official...e6 and ...d5: give White the center, then break it with ...c5 and ...f6. Winawer sharpness, Advance counterplay, Tarrasch clarity.
Queen's Gambit Declined
Official...e6, ...Be7, ...O-O: the setup that's held up at every level for 150 years. Solid against the Exchange, active against Bg5 and Bf4 mains.
Nimzo-Indian Defense
Official...Bb4 pins, doubles White's pawns, and fights for e4 without touching the center. Every major White system met with a clear plan.
Slav Defense
Official...c6 keeps the light-squared bishop free and the structure granite. Main-line ...dxc4 with ...Bf5, plus the Exchange and early sidelines.
Grünfeld Defense
OfficialLet White build the big center, then hit it with ...d5, ...c5 and the g7 bishop. The Exchange main line and every major try against it.
Sicilian Defense — White's Open Sicilian
OfficialThe main-line answer to 1...c5: 2.Nf3 and 3.d4, meeting the Najdorf, Dragon, Taimanov and Kan setups. This is the White side — for playing the Sicilian as Black, see the Najdorf and Dragon courses.
French Defense — White's Side
OfficialHow to meet 1...e6 as White: 3.Nc3 and the Steinitz, plus the Winawer, the Rubinstein and the exchange lines. This is the White side — for playing the French as Black, see the French Defense course.
Caro-Kann — White's Advance
OfficialHow to meet 1...c6 as White: 3.e5 grabs space and 4.h4 goes straight at the light-squared bishop. This is the White side — for playing the Caro-Kann as Black, see the Caro-Kann Defense course.
King's Indian — White's Classical
OfficialHow to meet the King's Indian as White: the Classical with Be2 and Be3, answering ...e5 and ...c5 breaks alike. This is the White side — for playing the KID as Black, see the King's Indian Defense course.
Open Games — Black's 1...e5
OfficialA complete 1...e5 answer to 1.e4: the Ruy Lopez, the Italian, the Scotch and the gambits, all from Black's side. The Black repertoire that was missing while every 1.e4 e5 course covered only White.
Scandinavian — White's Side
OfficialHow to meet 1...d5 as White: 2.exd5 Qxd5 3.Nc3 gains the tempo, then take the centre. Pairs with the Scandinavian bishop-hunt trap.
Pirc & Modern — White's Side
OfficialHow to meet 1...d6 and the Modern as White: 2.d4 and 3.Nc3, building the big centre Black invites you to build, then proving it.
Queen's Gambit Accepted
OfficialTake the pawn and give it back on your terms: 2...dxc4, then ...Nf6, ...e6 and a timely ...c5 to free the position. Black's side.
English Opening
Official1.c4 — the flank opening that keeps the centre in reserve. Meets ...e5, ...c5 and ...Nf6 setups, and transposes into d4 structures on your terms.
English — Black's Side
OfficialHow to meet 1.c4 as Black. The library had no answer to it at all, which meant a repertoire could look complete and leave you with nothing against one of the four most common first moves.
Réti — Black's Side
OfficialHow to meet 1.Nf3 as Black. Like the English, it was entirely uncovered — and it is the move most likely to transpose somewhere you have not prepared.
Alapin Sicilian — White's Side
OfficialMeet the Sicilian with 2.c3, build the big centre with d4, and play a normal game a tempo up in development. No Najdorf theory, no Dragon, no memorising twenty move orders — one system against everything.
French: Wing Gambit
OfficialAgainst the French, grab space with 3.e5 and then answer the ...c5 break by throwing a wing pawn at it: 4.b4! It takes the French player straight out of everything they have studied, and White scores 54% with it at club level. Tricky rather than refuting — which is the point.
Leningrad Dutch
OfficialAnswer 1.d4 with 1...f5 and fianchetto: ...Nf6, ...g6, ...Bg7, ...O-O, ...d6. Black takes the kingside space the Dutch is played for and keeps the ...e5 break in hand. Includes the Hopton Attack (2.Bg5), which is what you actually meet most often.
Evans Gambit
Official4.b4! — offer a wing pawn to rip open the centre with c3 and d4 while the bishop is still deciding where to stand. The most famous attacking gambit in chess, and it still scores.
Smith-Morra Gambit
OfficialMeet the Sicilian by giving up a pawn for the c3- and d-files. White develops fast, Black is behind, and the positions are far easier to play from White's side than the book says.
Danish Gambit
OfficialTwo pawns for two raking bishops on the long diagonals. Black can take both, decline with 3...Qe7, or hand one back with 3...d5 — all three are here.
Budapest Gambit
OfficialAnswer 1.d4 with 2...e5, throwing a pawn at the centre on move two. White keeps it with 3.dxe5 Ng4 and then has to survive the knight coming back — this is where the Kieninger Trap lives.
Albin Countergambit
OfficialMeet the Queen's Gambit with 2...e5, and after 3.dxe5 push 3...d4 — a pawn down with a wedge on d4 that cramps White for the whole game. Home of the Lasker Trap.
King's Gambit: the Cunningham Bishop
Trap4...Bh4+ looks like a free hit — it drives your king to f1. But the bishop now stands on h4 attacked by the knight on f3, and 5...Nf6?? loses it to 6.Nxh4. The most-played mistake anyone makes against this opening.
King's Gambit: the Qc6 Skewer
TrapThe Modern Defence 3...d5 gives the pawn back to free the position. After 4.exd5 Qxd5 5.Nc3 the queen is attacked and 5...Qc6?? picks the one square that loses her — 6.Bb5 pins the queen to the king.
King's Gambit: h6 and the Rook Lift
TrapAgainst 3...g5 you play 4.h4 and the g5 pawn is already loose. 4...h6 defends it — but 5.hxg5 hxg5?? forgets that the h-file opens with a rook staring down it. 6.Rxh8 wins a rook, and often a second one on f8.
Caro-Kann: the Ne5 Overreach
TrapIn the Exchange Caro-Kann, White pins with 5.Bb5 and then reaches for 6.Ne5 to make something of it. The knight is just hanging — 6...Nxe5 7.dxe5 Bxb5 leaves you a clean piece up.
Caro-Kann Fantasy: the ...e5 Battery
TrapMeet the Fantasy Variation 3.f3 by striking with 3...e5. After 4.dxe5 the queen goes to b6 — not d6, which hangs to exd6 — and lines up with the bishop on c5 against f2. The natural 5.Bc4? already loses material.
Caro-Kann: Fantasy Variation Trap
TrapAgainst the Fantasy Variation (3.f3), 4...e5! hits the center; White's greedy 5.dxe5?? loses to 5...Qh4+, when 6.Ke2 Qxe4+ or 6.g3 Qxe4+ wins by force.
Caro-Kann: Panov — the ...Bb4 Pin
TrapIn the Panov, 6...Bb4 pins the Nc3; White's natural 7.b3?? leaves the knight undefended, and 7...Bxc3+ 8.Bd2 Bxa1 wins knight and rook for the bishop.
King's Gambit: Allgaier Trap
TrapWhite's Allgaier knight sac 5.Ng5 and 6.Nxf7+ overreaches — after ...Kxf7 Black returns the pawns and keeps a whole piece; the sound 5.Ne5 only draws.
King's Gambit: Salvio Trap
TrapIn the Salvio Gambit White's greedy 7.Nxf7 (or any capture on f7/g4) runs into ...Nxf7 and drops a piece; only the retreat 7.d4 and 8.Nd3 holds equality.
King's Indian: Exchange — Punishing 9.Nxe5
TrapWhite snatches the e5 pawn with 9.Nxe5?; 9...Nxe4! unveils the g7-bishop and hits the c3-knight, and a knight retreat runs into ...Nxc3 and ...Bxc3+ winning the a1-rook.
King's Indian: Sämisch — the ...Nxg3 Shot
TrapIn the Samisch, 8.Qd2 Qh4+ 9.g3 invites 9...Nxg3!; the natural 10.hxg3 opens the h-file for 10...Qxh1, winning the rook, and declining still drops the f1-bishop.
Caro-Kann: Réti–Tartakower Trap
TrapAfter 4...Nf6 5.Qd3, Black's premature 5...e5?? runs into 8.O-O-O and the crushing 9.Qd8+!! queen sacrifice mating by force; declining with 5...Nxe4 keeps Black safe but hands White an easy game.
Caro-Kann: Smothered Mate Trap
TrapIn the 4...Nd7 line, 5.Qe2 threatens 6.Nd6#; Black's natural 5...Ngf6?? allows it, while the correct 5...Ndf6 leaves White comfortably better.
Scandinavian: the g4 Bishop Hunt
TrapAfter 5...Bg4 6.h3 Bh5, White plays 7.g4 — and Black's natural-looking 7...Nxg4?? sacrifice is unsound: 8.hxg4 Bxg4 leaves Black a piece down for two pawns with no attack. 7...Bg6 is the move.
Sicilian: Magnus Smith Trap
TrapBlack's Dragon-style 6...g6 in the Fischer-Sozin lets White play 7.Nxc6 bxc6 8.e5, when the natural 8...dxe5 loses the queen to 9.Bxf7+ Kxf7 10.Qxd8.
Sicilian: Nxe4 Fork Trap
TrapIn the c3-Sicilian, snatching the loose e4-pawn with 4...Nxe4?? runs into 5.Qa4+, a double attack that forks Black's king and stranded knight and wins it with 6.Qxe4.
Queen's Gambit Declined: Elephant Trap
TrapIn the QGD, White's greedy 6.Nxd5?? runs into 6...Nxd5! 7.Bxd8 Bb4+ — the check comes with tempo and Black emerges a clean piece up.
Albin Countergambit: Lasker Trap
TrapThe famous underpromotion. After 4.e3?? Bb4+ 5.Bd2 dxe3, White's natural 6.Bxb4 allows 6...exf2+ 7.Ke2 fxg1=N+! — a knight, not a queen, winning material.
Blackburne Shilling Gambit
Trap3...Nd4 offers the e5 pawn. 4.Nxe5 is playable for White — but the greedier 5.Nxf7?? loses on the spot to 5...Qxg2 6.Rf1 Qxe4+ 7.Be2 Nf3#.
Legal's Mate
TrapThe oldest trap worth knowing: 5.Nxe5! offers the queen, and 5...Bxd1?? is mated by 6.Bxf7+ Ke7 7.Nd5#. Black must decline — but then White has simply won a pawn.
Ruy Lopez: Noah's Ark Trap
TrapAfter 5.d4 b5 6.Bb3 Nxd4 7.Nxd4 exd4, White's natural 8.Qxd4?? walks into 8...c5 and 9...c4 — the b3 bishop is boxed in by a wall of pawns and cannot escape.
Budapest Gambit: Kieninger Trap
TrapIn the Budapest, 7.a3?? invites 7...Ngxe5 — and when White grabs the bishop with 8.axb4, 8...Nd3 is smothered mate on the board.
Ruy Lopez: Fishing Pole Trap
Trap4...Ng4 5.h3 h5!? dangles the knight as bait. 6.hxg4?? opens the h-file onto White's king and Black mates. It is a genuine gamble though: if White declines, Black is about a pawn and a half worse — those lines are included rather than hidden.
Smith-Morra: Siberian Trap
TrapIn the Smith-Morra Accepted, 9...Nd4 hits the queen — and White's natural 10.Nxd4?? allows 10...Qh2 mate, the queen slipping in behind the pawn wall.
Caro-Kann Fantasy: the ...Qb6 Battery
TrapAgainst the Fantasy (3.f3), 3...Qb6 hits b2 and d4 together. After 4.Nd2 e5, the natural grab 5.dxe5?? runs into 5...Bc5 — d4 has vanished, f2 is pinned, and the g1 knight is stuck. Note it needs 4.Nd2: against 4.Nc3 the same plan does not work.
