  Against the Indian Defenses

  373 games, 50.9%: your Nf3-Bf4-e3 system holds up, but three reflexes cost you points — castling too early against the fianchetto, 6.c3 against …c5, and 3.c3 where you should have advanced.

  22 cards, one idea each. Swipe to move on.

• The big idea

  Against 1…Nf6, you don't argue theory: you set up your system. Nf3, Bf4, e3, the bishop to d3 or e2, castle.

• The big idea

  Your file groups 373 games under this name (169 wins, 42 draws, 162 losses) for 50.9%, a hair above your overall score of 49.6%.

• The big idea

  1…Nf6 directly in 120 games, but also 1…d5 in 118 games, where the knight reaches f6 a move later and the positions merge.

• The big idea

  The system's deal is simple. You pay in ambition: no c4, no fight for the center from the start, and your opponent picks the structure.

• The big idea

  What you buy: a position you know by heart, a bishop on f4 that comes out before e3, and plans that repeat from one game to the next.

• The big idea

  The downside: when your opponent does something unusual, your autopilot keeps playing the same moves.

• The big idea

  That's exactly what your numbers show. Against …e6/…d5/…Bd6, your 5.Ne5 line scores 71% over 14 games: that's your weapon.

• The big idea

  Against the fianchetto, you castle out of habit and the 6.O-O Nc6 position drops to 14% over 7 games. Against …c5, you support d4 instead of advancing: 2.c3 after 1.d4 c5 in 22 games, 48%.

• The big idea

  This course plugs those leaks one by one.

• Principle

  The f4 bishop needs a retreat square

  Against the fianchetto, Black plays …Nh5 to chase your f4 bishop. With h3 played, it drops back to h2 and keeps the diagonal; without h3, it has to go to g5 or get taken on g3.

• Principle

  The e5 knight lives off its defenders

  Your games: 8× · 12% of points

  Qc7, Bd6 and Nd7 all target e5. Your knight holds as long as Bf4, d4 and a second knight on f3 support it. Count the attackers before every quiet move.

• Principle

  A check that costs castling

  When Black plays …c5 before castling, Bb5+ forces their king to move or a piece to block on d7, where it cuts the queen off from d6.

• Principle

  Against …c5, advance

  Supporting d4 with c3 gives back the advantage. With d5, you grab space and turn the c5 pawn into a pawn that no longer bites anything.

• Principle

  Your system is not a gambit

  Your games: 5× · 20% of points

  Your strength is a sound position you know better than your opponent. A move like 2.g4 hands them a pawn and the initiative in one go: the opposite of your deal.

• Imbalance

  Bishop f4 vs bishop d6

  Your games: 92× · 49% of points

  …Bd6 offers to trade your best bishop. If you let it happen with …Bxf4, your structure gets damaged; with 5.Ne5, you put your knight in front and keep the tension.

• Imbalance

  The d4 center vs the g7 bishop

  The fianchetto targets d4 and prepares …e5. If the center opens, the g7 bishop becomes Black's best piece; your h2 bishop is then its answer.

• Imbalance

  Space vs majority

  After d5 and exd5, you have space and a d5 pawn that splits Black's camp in two. Black has a queenside majority that will take a long time to roll.

• Imbalance

  h-file vs bishop pair

  When …Nxg3 takes your bishop, you give up the bishop pair. By recapturing hxg3, you get an open h-file aimed at the h6 pawn in return.

• The trade-off

  What you gain

  • A system you play with your eyes closed: the same plans come back game after game.
  • Against …e6/…d5/…Bd6, 5.Ne5 gives you the best line in your file: 71% over 14 games.
  • Concrete traps against Black players in a hurry: Bb5+ when …c5 comes before castling.
• The trade-off

  What you give up

  • Autopilot: you castle and play c3 where the position asks for something else.
  • Against the fianchetto, your f4 bishop becomes a target for …Nh5 if you forget h3.
  • Against …c5, supporting d4 with c3 gives back the advantage d5 would have kept.
  • Fancy moves: 2.g4 has brought you 20% over 5 games.
• That's all
