I’m referring to the easy looking, tricky to solve problems. I’ve heard them referred to by that term because they have been used at Moscow University to discriminate against Jewish students but I don’t know if they have other names.

There is some discussions and examples of such problems at https://arxiv.org/pdf/1110.1556.pdf and http://3038.org/press/shen.pdf.

Of course, just the phrasing made me think the "trick solution" was eugenics, not a university admission trick. Unfortunately, historically "Jewish question" or "Jewish problem" has referred to these concerns [0]. Of course, following your first link it seems like the native phrase for it is in no way better, but that seems predictable as it's stemming from a racist premise in the first place.

It's interesting that doing competitive math makes it really easy to spot these kinds of problems and guess at their "true" difficulty. Honestly, I'm kind of surprised that "this problem is short" or "the solution is short" would ever fly as a measure of how easy a problem is, but I assume that a system that is intended to encode racism doesn't need a whole lot of logic behind it…
