hikaru vs kids2010

Hikaru developed his dark‑squared bishop to b2 (**6.Bb2**) and castled long (**11.O-O-O**) to keep his king safe while the rook on d1 could later swing into the center. By playing **14.Bf5** and later **15.Rc1**, he placed his pieces on the open c‑file, creating threats that forced Black to defend rather than develop. This demonstrates the principle of coordinating pieces on open lines before launching an attack.

After the exchange on c5 (**12.dxc5 Nxc5**) Hikaru exchanged rooks on c8 (**24.Rxc8+ Bxc8**) and kept the bishop pair active, while his king stepped out to b1 (**13.Kb1**) and later to c3, supporting pawn advances. He also used the pawn break **22...f5** to open lines for his pieces, and his rook lift **16.Rhd1** prepared central play. These moves show how simplifying to a favorable endgame and improving king activity can turn a small material edge into a win.

With an extra pawn on the kingside, Hikaru advanced his h‑pawn with **49.h5** and then **50.h6**, creating a passed pawn that Black could not stop. Meanwhile his king and knight supported the pawn march, while Black’s bishop was stuck on the long diagonal. This illustrates the endgame principle of creating and advancing a passed pawn with the help of an active king.
