Catalan Opening Open Defense Discovered Attack Chess Puzzles

In the Catalan Opening, the Open Defense usually arises after 1.d4 Nf6 2.c4 e6 3.g3 d5, when White fianchettoes the bishop on g2 and Black accepts a more open central structure. A discovered attack in this setting often comes from moving a piece that uncovers the g2-bishop or a rook line, creating pressure on the d5 pawn, the queen, or a pinned defender. For an intermediate player, the key feature is the long diagonal pressure combined with central tension in an open or semi-open position.
