hikaru vs abhidabhi

White started with **b3** and **Bb2**, placing the bishop on the long diagonal where it eyes the central e5‑square (a fianchetto). After Black played ...d5, White answered with **d3** and later **e4**, establishing a solid pawn center while keeping the king safe by castling on move 9. This shows how a early bishop fianchetto can control key central squares and give the king a safe haven before the middle game begins.

White seized the initiative after Black’s queen entered the attack on move 19 (**Qc3**). By playing **Rad1** and then **Rb1**, White placed a rook on the open d‑file and later on the b‑file, ready to infiltrate the seventh rank. The queen’s move **Qf3** forced Black’s queen onto c2, allowing **Rxb7** to win a pawn and open the b‑file. Finally, the knight jump **Nxf6+** (move 29) sacrificed the knight to expose Black’s king and win material, forcing resignation. This sequence demonstrates the principle of coordinating heavy pieces on open files, creating multiple threats, and using a tactical sacrifice to finish the attack.
