Very interesting research. Maybe I missed something you wrote somewhere or that is somehow implicit or obvious (in the case, I am sorry for the dumb question), but I can not figure out which side is to move in the proposed problems. Always White to move? It depends on the chessboard orientation? TIA.

In mate in two problems it is always white to mov first :)

So I'm one of the only people who got the first problem wrong?

Cool. Cool.

you don’t have to tell anyone ;).. but you did get some of the harder ones, right?

I did. I think all the others. Above average speed for the last one, I think

I'm obviously missing something, because I have what I think is a really dumb/naive question: how does an engine need a depth of 31 find a mate-in-two (as it seems like you described at the very end)?

Hope my explanation on twitter made sense

I also meant to say: now I understand why looking at depth as an indicator of complexity makes some sense.
