Catalan for White – Part 3 + PGN January 7, 2026

When Dreev and Basso concluded their previous two volumes on the Catalan, they left one critical junction unexplored—the moment after 4.g3 Bb4+, where Black’s check forces White into a labyrinth of transpositions. This third installment confronts that complexity head-on, offering not just a repertoire but a conceptual framework for understanding why the same positions arise from wildly different move orders.

The leitmotif here is transposition as weapon rather than obstacle. Where many players see confusion in the multiple routes to similar structures, Dreev and Basso reveal a unifying logic: the early Bd2 creates a tempo advantage that subtly reshapes familiar Catalan positions. After 5.Bd2 Be7 6.Bg2 O-O 7.O-O, Black’s responses split into distinct strategic families—and White’s extra move proves useful in each.
