Indian: 1.d4 Nf6 2.Nf3 e6 3.e3 c5 4.Bd3

Definition

This move-order is a branch of the Queen’s Pawn Game that often transposes to the Colle System against an Indian-type set-up by Black. By delaying c3 and rapidly developing the dark-squared bishop to d3, White sidesteps large chunks of Nimzo-Indian and Queen’s Indian theory while keeping a solid central grip. The Encyclopaedia of Chess Openings (ECO) usually files the position after 4.Bd3 under code D05: “Queen’s Pawn Game, Colle System versus Indian Defences.”

Typical Move Order & Basic Ideas

1.d4 Nf6 – Black adopts a flexible Indian set-up.
2.Nf3 e6 – Prevents Bg5 lines and hints at a Nimzo/Queen’s Indian.
3.e3 – White locks in the c1-bishop for the moment but prepares Bd3 and a later e4. A key Colle hallmark.
3…c5 – Black hits the d4-pawn immediately, often aiming for …d5 or …b6.
4.Bd3 – The signature move. The bishop eyes h7 and supports a future e3–e4 thrust.

Strategic Themes

Central Tension: White maintains the pawn on d4 while preparing c3 or e4. Black must decide whether to capture on d4, play …d5, or adopt Benoni-style structures with …c5-cxd4.
Light-Squared Activity: The early Bd3 gives White pressure on the h7-square; typical attacking motifs involve Qe2, 0-0, and sometimes Ng5.
Flexibility vs. Theory: White avoids allowing …Bb4 (the Nimzo-Indian pin) and chooses a system less reliant on memorised lines.
Black’s Counterplay: Common plans include …d5 (transposing to a Tarrasch-like IQP position), …b6 & …Bb7 (Queen’s Indian flavour), or …g6 (King’s Indian set-up) followed by …d5.

Historical Perspective

The Colle System (named after Belgian master Edgard Colle, 1897-1932) was originally aimed at 1…d5 structures. When Indian defences surged in popularity in the mid-20th century, players searched for Colle-style move orders that avoided the Nimzo-Indian. The sequence 1.d4 Nf6 2.Nf3 e6 3.e3 became a practical weapon for club players and professionals alike—Boris Spassky and later Vladimir Kramnik employed it occasionally to limit Black’s choices.

Model Game

A short but illustrative encounter:

White achieved the typical Colle development with c3–c4 (here c4 came in one move) while Black reached an IQP structure. White’s pieces harmonise toward e4 and the kingside, showcasing the system’s strategic aims.

Practical Usage Tips

Do not rush c2-c3 if Black has already exchanged on d4—sometimes the knight belongs on c3 instead.
If Black plays …b6 and …Bb7, consider a quick c4 to fix the bishop’s diagonal and gain queenside space.
After castling, typical attacking set-ups are Re1, Nbd2, Qe2, and e3-e4, or the more direct Ng5, Qf3, and Bxh7+ sacrifices if Black is careless.

Interesting Facts & Anecdotes

Anand’s Youthful Surprise: Viswanathan Anand used this exact move order in the Asian Junior Championship 1986, scoring a 20-move miniature after a swift e4 break.
Computer Age: Engines evaluate the starting position as roughly equal (≈ 0.20) but practical results at club level heavily favour White due to the system’s coherence and Black’s greater choice of possible missteps.
Colle’s Legacy: Edgard Colle himself rarely faced Indian defences, yet his name lives on in this modern adaptation of his ideas.
