What the opening is really aiming for

After 1.Nf3 Nf6 2.b4 g6 3.Bb2, White has already committed to the b-pawn advance and developed the bishop to a long diagonal. The opening is not about immediate tactics; it is about setting a flexible structure and asking Black to respond accurately. In this line, Black to move has several sensible choices, and your task is to stay comfortable while the position remains balanced. The practical goal is simple: keep your pieces active, avoid drifting into passivity, and make sure your queenside space actually helps your game.

The critical drill position

Stockfish rates this +0.16, a tiny edge for White. That means you are dead level here, with neither side better out of the opening. This is exactly the kind of position where understanding matters more than memorising a flashy line. In the drill, focus on piece activity and on meeting Black’s most natural development without letting the position become awkward for you. The board is balanced, but you still need to play accurately to keep it that way.

What Black usually does here

The engine’s best move is Bg7, continuing Bg7 e3 b6 c4. That is also the most-played continuation in the database, with 63,162 games. The other common replies are d6, e6, d5, Nc6, and b6. Since Black often aims for steady development, you should be ready for a game where both sides build quietly rather than forcing immediate complications. The drill lets you rehearse that exact kind of middlegame start.
