lachesisq vs Witik

White exchanged the pawn on c5 with **5.dxc5**, opening the d‑file and gaining a tempo on Black’s queen side. By developing the bishop to e3 (**6.Be3**) and then to d4 (**8.Bd4**) White placed pieces on active squares that eyed Black’s queenside weaknesses, and castled early with **12.O-O** to keep the king safe while the rook could later join the attack (king safety).

White coordinated the queen and rooks to create a decisive infiltration. After the queen reached a6 with **24.Qa6**, she captured the pawn on a7 (**28.Qxa7**) and then delivered a checking blow on b8 (**29.Qb8+**) followed by a queen lift to f8 (**30.Qf8**), forcing Black’s king onto a vulnerable square. The final rook lift **31.Rg4** brought the rook into the attack, threatening mate and winning material, illustrating the principle of using heavy pieces to exploit open lines and weak king position (attack coordination).
