Catalan Opening Open Defense Fork Beginner Chess Puzzles

In the Catalan Opening Open Defense, White usually starts with 1.d4 Nf6 2.c4 e6 3.g3 d5, then develops the bishop to g2 and often pressures the long diagonal. The fork theme appears when a knight or pawn can attack two valuable pieces at once, often after the center opens and Black's pieces become slightly loose.
