The Indian Defense: Anti-Grünfeld, Basman-Williams Attack opens with the sequence d4, ♘Nf6, ♙c4, and ♙g6, showing a typical hypermodern approach, where Black allows White to occupy the center with pawns, intending to undermine it later. The move ♙h4 marks an aggressive choice by White, aiming to launch a pawn storm on the kingside while neglecting immediate central development.
Best Moves
The Solid ♙c5
The move ♙c5 challenges White’s center and aims to open lines quickly for Black’s pieces. This move prepares for an early ♙d5, increasing influence over the critical central squares. By choosing ♙c5, Black looks to derive play against White’s advanced h4 pawn, which weakens the kingside and distracts from White’s usual center control strategy.
The Developmental ♗Bg7
Developing the bishop to ♗Bg7 follows the main idea of the fianchetto setup. This reinforces control over important central squares and supports plans involving ...d5. The bishop on g7 is also ideally placed to oppose White's pawn center and prepare for rapid kingside castling.
The Controlling ♙c6
Playing ♙c6 bolsters Black's pawn structure, intending to establish a robust center with a quick ♙d5. This setup can defend against the aggressive pawn thrust h4 while gradually aiming for a solid setup to coordinate piece activity effectively against any overextension of White.
The Defensive ♙d6
Selecting ♙d6 is a more conservative approach, intending to maintain solid positioning. This move maintains flexibility, allowing future development moves like ...e5 or ...c5 to combat White's central ambitions, while preparing for the king's safety with ♙O-O.
The Direct ♙d5
Playing ♙d5 immediately confronts White's center, striving to disrupt the coordination between White's pawns. Tension in the center creates opportunities for piece-play and undermines the aggressive ♙h4 pawn advance by questioning White's central occupation early.
Important Alternatives
The Adventurous ♙h5
Although less optimal, the move ♙h5 intends to directly oppose White's pawn on h4 and prevent further advance. This creates a dynamic pawn structure where both sides may contest control over the kingside. However, it leaves Black's own kingside slightly compromised and is more of a tactical restraint than a structural improvement.
Critical Mistakes
The Tempting ♘Nh5
While ♘Nh5 seems like an attempt to counteract the h4 pawn aggressive advance by White, it critically misplaces the knight and allows White to gain strong central control and outpost occupations. The knight on h5 can be vulnerable to attacks from White’s pieces, leading to potential tactical blows that disrupt Black's coordination and piece safety.
Conclusion
In the Indian Defense: Anti-Grünfeld, Basman-Williams Attack, play revolves around striking a balance between counter-attacking the center and maintaining piece safety. Moves like ♙c5 and ♗Bg7 offer sound structural advantages by preparing to challenge White's central ambitions while ensuring safe development of Black's key pieces. Meanwhile, avoiding mistakes like ♘Nh5 ensures that Black maintains a strong foothold without compromising piece placement or coordination.
