At move 6 Black chose the pawn push 6…e6. The move does not develop a piece and leaves the knight on g8 still undeveloped. It also blocks the c8‑bishop’s diagonal and creates a permanent weakness on d6/e5. The only concrete threat in the position is the capture on d4, but by playing e6 Black does not increase that pressure. Moreover White’s knight on e4 is completely undefended, yet Black’s move does nothing to exploit it; instead Black’s own pieces on a8 and g7 remain undefended.

The engine recommends 6…Nf6. Developing the g8‑knight attacks the undefended e4‑knight and prepares to recapture with the queen after 7.Nxf6+. This line wins material (exchange) and simultaneously increases pressure on the d4 pawn. By contrast, 6…e6 merely wastes a tempo, blocks the dark‑squared bishop and leaves Black’s position passive. The engine’s move creates an immediate tactical target and follows the opening principle of rapid development.

Develop before pushing pawns: In the opening, each move should increase piece activity or create concrete threats. Unnecessary pawn moves that block your own pieces give the opponent time to seize the initiative.
