Catalan Opening Discovered Attack Chess Puzzles

In the Catalan Opening, the defining feature is White's fianchettoed bishop on g2, often aimed at the long diagonal after 1.d4 Nf6 2.c4 e6 3.g3. A catalan opening discovered attack happens when that bishop's line is suddenly opened by moving a blocking piece, so the bishop attacks a new target with tempo. The classic idea is that a pawn or knight steps away and reveals the bishop's pressure on the queen, rook, or a pinned piece.
