Debiut Grob: Keene Obrona, Główny Wariant
A00Główna idea białych
White aims to fianchetto the light-squared bishop to pressure Black's center, while using the g4 push to provoke weaknesses. The plan is to undermine Black's pawn chain with c4 and d4, targeting the d5 square and preparing Nc3 to challenge Black's central control.
Główna idea czarnych
Black builds a strong pawn center with d5 and e4, supported by c6. The knight on e7 eyes f5 and g6, while the bishop on d6 pins potential Nf3 moves. Black seeks to consolidate the center and launch a kingside attack against White's weakened g-pawn.
