This line is a sharp and strategic continuation in the Queen's Indian Defense where Black immediately challenges White's setup by developing the bishop to a6, targeting White's critical c4 pawn and then delivering a check with Bb4+. The check forces White to address the pin on the knight or the potential weakening of the queenside structure.
Characteristic of the move Bb4+: This check aims to disrupt White's smooth development and provoke a weakening move or a concession in White’s pawn structure. It is a tactical and positional tool that applies immediate pressure.
