This course presents a complete White repertoire against the Dutch Defense based on 1.d4 f5 2.Bg5, a positional approach that immediately removes Black's Classical and Stonewall setups from the board. Against Black's most critical response, 2...h6 3.Bh4 g5 4.e3 Bg7 5.Bg3 c5 6.c3 Qb6, the repertoire centers on the novelty 13.Qd1!N, which yields White a lasting edge in the line Black relied on for equality. All major alternatives to 2.Bg5 are covered, including 2...Nf6, 2...g6, 2...d6, 2...c5, and 2...c6.
