I was searching for a question I read last week because want to share with my brother. The problem is when you search the term "chess" the question I want appear on the first position (because is the most recent), but the link take me to the same question as the one on second position.
I notice that you just created your account - probably when you came to ask this meta question.
This isn't a bug, it's status-bydesign.
From the Duplicates FAQ on MSE:
Furthermore, if the question is unanswered, and there is only one target, then anonymous visitors are automatically redirected to the duplicate.
If you're logged in, you get the actual question you click on, which is why it "works" now... you created an account here.
This was implemented back in 2012.
