Czech Benoni - Closed Centre
In the Czech Benoni Black closes the centre with ...e5 and develops calmly (...Be7, ...Nbd7, ...O-O). The play revolves around pawn breaks: ...f5 for Black, f2-f4 or b2-b4 for White.

Move by move
- 1.d4 – White occupies the centre with the queen's pawn and frees the c1 bishop. Against 1.d4 this course offers two systems based on ...c5: the Benko and the Benoni.
- 1...Nf6 – A flexible move: it controls e4, stops 2.e4 and does not yet reveal the structure. It is better to wait for 2.c4 before ...c5, so that White cannot answer with a comfortable e2-e4.
- 2.c4 – White gains space and controls d5. However, the c4 pawn will support a future pawn on d5: it is exactly the target the Benko will hit with ...b5.
- 2...c5 – Black hits d4 at once. After 3.Nf3 cxd4 the structures become symmetrical; the main reply is 3.d5, which gains space but creates the c4-d5 chain that Black will undermine.
- 3.d5 – White advances, gaining space and taking c6 away from the b8 knight. Now the d5 pawn depends on c4: Black can choose between ...b5 (Benko) and ...e6 (Benoni).
- 3...e5 – The Czech Benoni: Black closes the centre at once with pawns on c5 and e5. The play will be slow and manoeuvring, with flank breaks such as ...f5 or ...b5.
- 4.Nc3 – White develops and prepares e4. With a closed centre the knights are valuable pieces, because outposts matter more than diagonals.
- 4...d6 – Black completes the c5-d6-e5 chain. Now his c8 bishop is free, while the f8 bishop will stay behind the dark-square pawns.
- 5.e4 – White occupies e4 and gains space. He has more space in the centre and on the kingside; his typical plans are f2-f4 or b2-b4.
- 5...Be7 – Modest but coherent development: the bishop defends d6 and the kingside and allows castling. With a closed centre a long diagonal is not needed.
- 6.Bd3 – The bishop goes to d3, behind the e4 pawn, leaving e2 free for the g1 knight, which can then go to g3 and support f4.
- 6...Nbd7 – The knight develops without blocking the c8 bishop and prepares to manoeuvre: it can go f8-g6 or to b6 depending on the chosen plan.
- 7.Nge2 – The knight goes to e2 so as not to block the f-pawn: White keeps the f2-f4 option open and can bring the knight to g3.
- 7...O-O – Black castles. Now he must choose his break: ...Ne8 and ...f5 on the kingside, or ...a6, ...Rb8 and ...b5 on the queenside.
- 8.O-O – White castles and keeps the f2-f4 and a3-b4 options. With the centre closed nobody is in a hurry: the side that carries out its break better will prevail.
How to exploit the position
A closed position: White has more space, Black has a solid structure and the e5 square as a base. The side that executes its break better will prevail.
- The ...f5 break after ...Ne8 and ...g6: it attacks e4 and opens the f-file for the f8 rook.
- Alternative on the queenside: ...a6, ...Rb8 and ...b5, using the rook on the b-file.
- If White plays f4, answer ...exf4 and bring a knight to e5, the strong central square.
Master tips
Prepare ...f5 with ...Ne8
In the Czech Benoni Black's main break is ...f5, attacking e4, the base of White's chain. First the f6 knight must move.
