Open Catalan

1.d4 Nf6 2.c4 e6 3.g3 d5 4.Bg2 dxc4

The Open Catalan occurs when Black accepts the gambit pawn with dxc4. This leads to sharp tactical play where White gets excellent compensation through the powerful bishop on g2, superior development, and central control. The resulting positions often feature complex pawn structures and dynamic piece play.
