Natasha Jonas was one of four British boxers to move convincingly into the semi-finals at the European Women's Championships in the Netherlands.
Light-welterweight (64kg) Jonas, 27, produced an impressive performance to beat Russia's Anastasia Bellyakova.
Featherweight (57kg) Lisa Whiteside, middleweight (75kg) Savannah Marshall and flyweight (51kg) Nicola Adams also won to join Jonas in the last four.
But Nina Smith (featherweight) lost to Turkey's Ayse Tas on double countback.
Jonas, a two-time European Union amateur boxing champion, said: "Russia are always a difficult team. We went there for a camp in February and she beat me so it shows how far we've come.
"I'm not here for anything less than a gold. The tournament is not finished, you can relax a little knowing you've got a medal but I'm here for gold."
Six boxers travelled to Rotterdam representing England and all but Whiteside are also members of Great Britain Boxing's Olympic squad.
The three Olympic weight categories in women's boxing are flyweight, middleweight and lightweight.
