Intro
1. d41… d52. c42… e63. Nc33… Nf64. Bg54… Be75. e35… O-O
What you're training
Hold the centre with ...d5 backed by ...e6, develop classically with ...Nf6, ...Be7 and ...O-O, then free the position with the right break: usually ...c5, sometimes ...e5.
Strengths
- Declining with ...e6 keeps a firm pawn on d5 and a sound chain — Black trades a little space for great solidity.
- The whole middlegame revolves around Black's freeing breaks: ...c5 to challenge d4, or ...e5 when it can be prepared.
- Black's main practical task is the light-squared bishop on c8, hemmed in by ...e6 — develop it to b7 (after ...b6) or trade it off after a timely ...dxc4.
- It's a complete, principled system: easy to understand, hard to break, and a foundation that improves your whole positional game.
Watch out for
- Don't leave the c8-bishop buried — without a plan to free it (...b6 and ...Bb7, or ...dxc4 and ...b5) it stays the 'problem bishop' all game.
- Sitting passively invites White's minority attack (b4–b5) to chew up your queenside; you need an active break of your own.
- Releasing the central tension with an early ...dxc4 without a follow-up just hands White a free, strong centre — time that capture carefully.
