1of 9 patterns
Pattern A · The bishop escaped

Anti-Colle Defense (…Bf5 / …Bg4)

  1. What Black wants: To get the bishop out early before locking it behind e6.
  2. When Black plays Bf5. Black wants to solve the “bad bishop” problem before …e6 and trade White’s attacking Bd3.Once Bxd3 Qxd3 is played, the position becomes stable but less dynamic
  3. Hidden trick: They want to swap your bishop on d3, your best attacking piece.
  4. Main adjustment: Consider c4 early so Black cannot enjoy a completely comfortable setup. Challenge d5 before starting a kingside attack.
  5. Simple goal: Develop with tempo, protect d4, and decide whether exchanging bishops helps your centre.
  6. When Black plays Bg4, ask what is really pinned. Use Nbd2, Be2, or h3 only when each move improves your position—do not push kingside pawns automatically.
When Black plays Bf5, swap the bishops — then take over the town square with c4 and e4!
When Black plays Bg4, first finish development. Nbd2, Be2, or a carefully timed h3 can question the pin.
Bf5 = Fight for the center! Aim for open files and a safe king.
Bg4 = Defend against the pin, then look for Bxh6 and kingside attack.
Playing c4 as White is the best response when Black gets their bishop out early!
Pattern B · The centre was challenged

Classical Defense (...e6 and ...c5)

  1. What Black wants: To strike early with ...c5 and weaken your Colle triangle (pawns on c3, d4, e3).
  2. How Black wins: If your wall falls, Black gets the center and open lines for their pieces.
  3. White’s plan: Build up safely with Nbd2, O‑O, Qe2, then break open the center with e4!
  4. When to attack: Wait until all pieces are ready — then go for e4 and Bxh7+ (Greek Gift)! If the king is weak, sacrifice is the secret weapon.
  5. Winning clue: If Black’s king has no helpers, look for the Greek Gift combo. If it’s not safe, use open files and outposts for your pieces.
Build your Colle triangle: c3, d4, e3. That's your super-strong wall!
Watch out for ...c5! If they try to break your wall, fight back in the center!
Pawns are keys: When you play e4, your pieces get super active!
Greek Gift Alert! Bishop to h7 (“Bxh7+”) can surprise the king, but only if you built up first!
Swing your rook: Bring Re1 and Re4 or Rh4 — teamwork wins.
When in doubt... If a direct attack’s not ready, use the open files and control the center!
Pattern C · A kingside fianchetto

King's Indian Setup (...Nf6, ...g6, ...Bg7)

This setup asks you to change gears.
If Black gives you room, use it to prepare a well-supported central break.

Against the King’s Indian setup, White must eventually break the center — usually with e4.

  1. What Black wants: To keep a flexible pawn wall (…d6, …g6, …Bg7) where their bishop is like a laser and e5 is a key break!
  2. White’s plan: Build a Colle triangle, then fianchetto the queen’s bishop with b3 and Bb2—this is the Zukertort twist!
  3. When to break: Pause until all your pieces are ready; then try e4 or d5. You can swap pawns and use open files for your rooks.
  4. Watch out: If Black plays …e5 and attacks the center, defend with trades and use your fianchetto bishop as a helper!
  5. How to win: Use teamwork: knight, bishop, and queen all pitch in. If Black tries kingside attacks, stay calm and defend — then counterattack with your powerful pieces.
If Black plays ...g6 and ...Bg7: Their bishop is strong, but your Colle triangle and fianchetto are mighty too!
Try b3 and Bb2: The “Zukertort” trick lets your bishop help defend and attack.
Don't rush e4! Wait until every piece is ready, then open the center.
When you play dxe5: Open the center and activate your rooks—they love open lines!
If Black attacks kingside with their queen or bishop: Defend carefully, and remember your fianchetto bishop protects you!
Teamwork wins! Knights, bishops, queen and rook all help—when pieces are working together, your attacks and defenses are strong!
Pattern D · A pin or long diagonal

Nimzo & Queen's Indian Ideas (...Bb4 / ...b6)

  1. What Black wants: To pin your knight with ...Bb4 or use their bishop and pawns to control the center from afar.
  2. How Black wins: If you panic about the pin, you lose time and might miss your attack.
  3. White’s plan: Block the pin with Nbd2 and complete your Colle triangle. Don't let their bishop boss you around!
  4. When to break: Wait until your rooks are connected, then play e4 or c4 to open the center and remove Black’s control.
  5. Winning clue: Stay calm! Unpin, defend, and use your triangle to fight for the center. Your pieces become strong when they work together.
If Black pins your knight (Bb4): Don’t panic! Block the pin with Nbd2 and keep building your triangle.
If Black plays b6/Bb7: Their bishop is far away. Your plan is still Colle—aim for central control and open lines.
When you’re fully set up: Break with e4 or c4 to challenge Black’s hold on the center!
Remember: Pins aren’t forever. Once your queen and rooks are ready, you can unpin, trade, and attack!
Don’t rush: Develop calmly—let your triangle (c3/d4/e3) give you power, then play actively.
Teamwork makes you strong: Knights, bishops, and queen all help to defeat annoying pins and distant bishops!
Pattern E · A c4 transposition

Budapest Gambit: Black's Surprise after c4

Move-order truth: This is not forced by a pure Colle setup. It appears only after White chooses an early c4 and transposes into Queen’s Gambit territory.
  1. What Black wants: After White has committed to c4, Black strikes with ...e5, develops quickly, and uses ...Bb4+ or queen pressure to regain the pawn.
  2. Black's tricks: If you play f3 or build your Colle wall too soon, watch out for sudden Bb4+ and Qh4 shots. Black's pieces swarm when you try to be solid!
  3. How White should defend: Don't fight for the pawn! Instead, develop quickly, return the pawn if needed (try e4!), and never rush f3 unless you’re sure.
  4. Best tip for White: If you see e5 and Black’s knight on g4, play e4 and finish development. Castle early and block checks with your knights—not with pawns or bishops. Don’t let them pin your knight and attack your king!
  5. When safe, exchange pieces and steer to the endgame—your Colle bishop grows stronger as the board opens up.
Black’s surprise: The Budapest exists only after your c-pawn reaches c4. Develop quickly, and don’t play f3 too soon.
If Black pins you with Bb4+, block with a knight (Nc3 or Nbd2) rather than a bishop.
Best defense: Play e4 early if safe, or simply develop and castle. Don’t chase pawns in the opening!
When in doubt: Don’t let Black pile up on your king! Exchange queens or trade attackers if you feel under fire.
Pattern F · A solid pawn triangle

Slav Triangle & Chebanenko Setup (...d5, ...e6, ...c6, ...Nbd7)

  1. What Black wants: Build a strong triangle with pawns on c6, d5, and e6 to wait and see what you'll do.
  2. This setup is extra solid—Black doesn't attack quickly, but blocks your Colle plans and keeps every piece waiting.
  3. How you win: Use quick development: Nbd2, Bd3, O-O, and play e4! If Black doesn't play ...c5, you can sometimes push c4 and open the center.
  4. Simple goal: Don't rush—build up your Colle triangle, look for opportunities to play e4, and get your pieces working together for a central break.
  5. If Black ever plays ...c5, use your Colle “B” plan and break the center with e4. If they wait, prepare to open the board in the middle or swing your rook to fight for open lines!
Black's triangle is tough, but you can break through with e4 and teamwork!
Be patient—wait for the right moment to push e4 or c4, then open up the center and launch your attack.
If the board stays closed, use your knights and bishop to look for outposts.
Pattern G · A closed Stonewall

Stonewall Defense (...f5, ...e6, ...d5, ...c6, ...Nf6)

  1. What Black wants: Build a wall with pawns on f5, e6, d5, and c6 to create a fortress and attack your king-side later.
  2. This wall is strong but leaves a big hole on e5—your knight loves outposts!
  3. How you win: Put a knight or bishop on e5 to attack the wall from behind, or play c4/e4 to break the wall down.
  4. Simple goal: Play slowly, use pawn trades, and sneak your knight to e5 or c5. Your pieces are sneaky outpost explorers!
  5. If Black gets busy with queenside pawns (like ...b6), look for chances to open the center and swing your rook around.
Find the weak spot—outpost on e5! Your knight is a superhero here.
If the Stonewall is too strong to break, swap pawns and open files slowly.
Team up with your pieces—rook swings and bishop attacks can help crash through the wall.
Pattern H · A queenside pawn race

Hybrid: Early Queenside Expansion (...a6, ...b5, ...Bb7)

  1. What Black wants: To play …a6 and …b5 and push their pawns quickly on the queenside, then attack with their bishop.
  2. This plan is very common in blitz and online games—watch out for quick attacks on your Colle triangle!
  3. How you win: Stay calm, develop with Nbd2, Bd3, O-O, and interrupt their plan with c4 if their pawns get too close.
  4. Swing a rook to the queenside, or use your bishop to defend. If you open the a- or b-file, your rook becomes a hero!
  5. Simple goal: Don't panic. Let Black push on the side, but control the center and use open files for your attack.
If Black rushes their pawns on the queenside, defend the center—then strike back with c4!
Swing your rook to the open file—rook teamwork wins prizes.
Bishops on the long diagonal can block their attacks—don't let Black’s pawns distract you!
Pattern I · Fast knight pressure

Chigorin Defense (...Nc6 early pressure)

  1. What Black wants: Develop quickly with ...Nc6 and put pressure on your pawn on d4.
  2. This move blocks Black’s c-pawn, so they are playing actively instead of solidly.
  3. White’s plan: Don’t panic! Continue your Colle setup with e3, Bd3, O-O, and Nbd2.
  4. Important rule: If Black pins your knight with Bg4, play Nbd2 before pushing e4.
  5. How you win: Once your pieces are ready, break the center with e4 and start your kingside attack.
If Black plays ...Nc6: Stay calm and build your Colle setup.
Don't rush! Develop Nbd2 and castle before attacking.
Center break: When ready, push e4!
Remember: Black blocked their c-pawn, so their center may become weak later.
