Hübner Variation — 4.e3 c5 5.Ne2

Robert Hübner’s system delays Nf3 in favour of Ne2, fortifying the c3-d4 chain, sidestepping pins, and reserving f-pawn flexibility. Expert sources (ChessBase, Lichess Masters, ECO B) confirm its strategic depth.

Black challenges with ...cxd4, ...d5, or ...b6, while White prepares f3–e4 or c5 outposts, leading to long manoeuvring battles.
