The 24-year-old started the race offensively and was in the lead until the last meters, but ended up second in the heat.
It gave Kramer a ticket to the final, even though it was a bit messy about who would go to the final.
- It's been a bit tricky.
First it was 2 + 0, then 1 + 4, then 2 + 0 again.
They have had some technical problems.
It took a long time before we got to see the heat yesterday, it is clear that all athletes became a little frustrated, says Kramer to SVT Sport.
"Talked through the tactics"
One of the pre-favorites Elliot Giles, from the UK, was missing after injuring himself in the warm-up.
He should have run in Kramer's heat.
- I think he warmed up, but then he did not show up.
I just took note and talked through the tactics again, says Kramer.
Aiming for a medal
The final will be decided on Saturday.
That's where Kramer avoids one of the worst competitors now that Giles is missing.
- That was what (final) I came here for.
There are eight of them there and I am aiming for one of the first three places, he says.
