Botvinnik System

1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.g3 Bb7 5.Bg2 c5

Black plays an early ...c5 to hit White's center immediately. This creates a more dynamic Queen's Indian where timing and tactical awareness matter: the long diagonal is strong, but the position can open quickly.

Main Idea

Strike with ...c5

Typical Plans

Black: Pressure on d4

...c5 and ...Bb7

Black tries to force exchanges or create targets in the center, often opening lines for pieces.

White: Stabilize the Center

d5 or e3 setups

White chooses between advancing, exchanging, or supporting the center, depending on piece placement.

Watch Tactics

Pins and discovered attacks

As the position opens, tactics on the long diagonal and the c-file become more common.

More Dynamic Queen's Indian

If you want earlier contact and a more open position, this ...c5 approach is a good choice.
