hikaru vs Tunartank

Hikaru developed his pieces naturally: after **3.c4** he met Black’s bishop check with **4.Nbd2**, then played **5.a3** to force the bishop exchange and recaptured with the knight on **6.Nxd2**. He fianchettoed his dark‑squared bishop to **6...Bb7**, giving the queen‑side a long‑range defender and controlling the central e4‑square. This illustrates the principle of completing development while keeping the king safe (castling later at move 14).

When the position opened on the queenside, Hikaru seized the initiative with **24.Rxa8** followed by **24...Rxa8**, forcing an exchange of rooks that left him a piece up. He then used the open a‑file to bring his queen into the attack with **26.Qxa1** and later **30.Qc2**, while his pawn on b5 created a passed pawn and restricted Black’s pieces. The key tactical blow came at **28.Bxc5**, eliminating a defender and allowing the queen to infiltrate; after **32.Bxd3** and **33.Qxd3**, White’s queen dominated the board, culminating in the winning check **37.Qb3+**. This demonstrates how winning material at the right moment and then activating the queen can convert a small advantage into a full win.
