Catalan Formation

1. g3 d5 2. Bg2 e6

White's kingside bishop takes the long diagonal.

The first 4 moves, explained

• 1. g3 Prepares the fianchetto: the bishop will take the long diagonal via g2. Theory calls this the Hungarian Opening.
• 1... d5 Stakes a claim in the centre, controlling e4, and frees the bishop and queen.
• 2. Bg2 Fianchettoes the bishop onto the long diagonal, pressuring d5 and e4 from a distance.
• 2... e6 Supports the centre, adding control of d5. Theory calls this the Catalan Formation.
