The Van't Kruijs begins with 1.e3, a modest move that opens the f1-bishop and waits for Black to reveal a center. Its value is not a forced advantage but choice: White can transpose into d4, c4, or b3 structures, while Black can equalize by taking space. Learn both sides of that bargain, including the one concrete queen trap Black must respect.
Study eight direct lines: the symmetrical 1...e5 center, the Amsterdam Attack, two 1...d5 structures, the 1...Nf6 fianchetto, the 1...g6 broad center, and Black's classical and ambitious counters. Each line names the structural decision that makes the move order useful.

Based on the full guide: every move and board comes from the Van't Kruijs Opening guide, its four playable branches, and its complete position set. The five guide tests retain Bb5+ (+4.62), ...e4 (+0.44), ...Bb4 (-0.05), ...e5 (+0.40), and ...e5 (+0.12).
The 16 boards train the d4 challenge, Amsterdam development, Caro-Kann exchange structure, overextended center, queenside fianchetto, King's Indian-style break, Black's classical setup, and the forcing Bb5+ queen trap. Every wrong move receives an immediate legal reply.

Choose one of six verified starts and set the opponent from 600 to 2500. Twelve direct coach rules recognize the central choice, h3 prophylaxis, Amsterdam pin, c3 support, queen trap, c4 and e5 breaks, fianchetto recapture, and both Black counterplans.
The six starts contain the exact 1.e3 base, verbatim seeds for 1...e5, 1...d5, 1...Nf6, and 1...g6, plus the queen-trap position after ...Bxd1. Every paired goal uses the same original identities and deadline.
