Moves: 1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. g3 Ba6 5. b3 Bb4+ 6. Bd2 Be7

The move 5...Bb4+ is characteristic of the Check Variation, forcing White to react immediately and slightly disrupting White’s natural development.
The subsequent 6...Be7 is an intermezzo (in-between) move that prepares Black to castle quickly and keeps flexibility in the position.
Characteristics: Black's fianchettoed bishop on a6 targets the critical c4 pawn and exerts influence on the long diagonal. The check with Bb4+ is a tactical motif designed to gain a tempo and provoke a concession from White.
From Black’s perspective, this opening is solid and somewhat defensive, focusing on controlling key squares and preparing counterplay rather than immediate attacking chances. White, meanwhile, maintains a strong center with pawns on d4 and c4, aiming for central control and flexible development.
Center Control: White clearly aims to control the center with pawns and pieces, while Black applies indirect pressure rather than contesting the center outright at this stage.
