Last year the Czech U18 beat Canada 4-2 in the quarterfinals! But that was a complete sensation. (I think they won silver in the end, lost the final against the US if I am not mistaken.
Only losing 2-4 against Canada is actually not too bad, given that the gap between Canada and the US on the one hand and the rest of the world on the other is much, much bigger than in the case of the men and even the juniors (where it if of course bigger than with the adults).
The Czech women (junior and senior levels) are pretty good at the knockout stages in recent years - they can lose 1-8 or, as happened this year, 0-5 against Canada in the round robin, but then keep it tighter at the knockout stages and occasionally win. I think the women are legit number 3 now. Mostly beat Sweden (junior, senior level) and marginally more often than not Finland. It used to be a very, very different situation in the past, they caught up massively in the past 10-15 years, and overtook most teams. The senior women had never even made a semi-final until 2022, and then won bronze twice and once lost to Finland (SO). The senior women's last 10 games against Sweden: 8-2 Czech wins. Against Finland: 6-4 wins.
Less than 10 years ago I barely knew that the Czech Republic even had a women's ice hockey team.
