The Four Knights reaches symmetry quickly, but the fourth move can turn it into five very different games. Learn how d4 changes the pawn structure, why Bb5 invites Spanish plans, when Bc4 allows ...Nxe4, and how g3 keeps White flexible. From Black's side, practice the ...d5 break, Rubinstein liquidation, and two concrete tactical punishments.
Study four White roads and four Black responses. The lines cover the Scotch structure, Spanish Metger plan, Glek fianchetto, Anti-Petroff route, Rubinstein liquidation, Italian refutation, and ...Bc5 trap. The board supplies move context while per-move editorial notes wait for the later Opus pass.
