gmwso vs Sanan_Sjugirov

White set up a flexible opening by fianchettoing the king's bishop with **3.Bg2** and castling early with **4.O-O**, keeping the king safe while retaining central tension. By playing **5.c4** and later **6.b3**, White prepared the long diagonal for the bishop and kept the pawn structure fluid, showing the principle of developing pieces to active squares before committing the central pawns.

White created a powerful passed pawn with **30.c5**, forcing Black's knight to retreat to **30...Nf6** and opening the c‑file for the rooks. The move **42.Rb6** placed a rook on the seventh rank, directly attacking Black's pawn on b6 and limiting the king's mobility. After winning the b‑pawn with **45.Qa4** and **46.Qxa6**, White exchanged queens and then seized the initiative with **47.Rxc6**, removing a key defender and preparing the decisive infiltration with **48.Rc8+**. This sequence demonstrates how advancing a passed pawn and using rooks on the seventh rank can generate overwhelming pressure.

In the final phase White turned the material edge into a winning endgame by promoting the c‑pawn with **49.c6** and then capturing on d7 with **50.cxd7**, creating a second passed pawn and forcing Black's rook onto the second rank. The coordinated attack of the bishop on b4 and the rook on g1 (later **52...Rg1**) trapped Black's king, and the series of checks (**53...Rg3+**, **54...Rg2+**, **55...Rf2+**) forced the king into a corner. This illustrates the endgame principle of using active pieces to restrict the opponent's king while advancing passed pawns to promotion.
