Game Snapshot
Catalan: Open, 5.Qa4+
Master Lens
GMWSO steered the Catalan Open into a comfortable lead by using an early queen check to gain a tempo and develop smoothly, then turned that advantage into a winning attack in the middlegame. The decisive queen move **18.Qb5** created unstoppable threats, forcing Black to resign. This game shows how precise opening play and coordinated piece threats can convert a small edge into a full win.
What The GM Did Well By Phase
Opening
White began with the check **5.Qa4+**, forcing Black's bishop to block on **5...Bd7**. This forced move gave White a tempo (a useful extra move) and let White capture the pawn on c4 with **6.Qxc4**, regaining material while Black's pieces were still undeveloped. The early queen sortie and quick development of the fianchettoed bishop (a bishop placed on the long diagonal) gave White a lead in piece activity, illustrating the principle of gaining time (tempo) in the opening.
Middlegame
After Black's knight jumped to **11...Ne4**, White answered with **12.Nc3**, inviting the exchange **12...Nxc3** and then recapturing with **13.bxc3**. This kept White's pawn structure solid and opened the b‑file for the rook, which later moved to **17.Rb1**. The key finishing move **18.Qb5** attacked the b7 pawn and the knight on c6 at the same time, creating a double threat (a fork) that Black could not meet. This demonstrates how a well‑placed queen can coordinate with other pieces to generate decisive threats.
