Grob Opening
Overview
Grob Opening is one of the foundational chess openings, sitting at the root of an entire branch of theory under ECO code Flank Openings in the A00 group.
The Flank Openings group covers flank openings — systems that delay the central pawn break and instead develop pieces and pawns on the wings.
Play reaches this position via 1. g4, after 1 ply of opening development.
It is the root of 7 named variations, with Alessi Gambit, Double Grob, Grob Gambit, and others among the most studied.
In total, the branch covers 19 sub-variations across all depths.
