Uh it's not trolling, the puzzle code probably just saw there was a passed pawn somewhere on the board, so it decided to add the "Passed pawns" theme.
Puzzles suggestion "Passed Pawns" is just major trolling.
It's a well-known bug. A passed pawn somewhere on the board does not turn it into a theme. That's why having a chess interface is not the same as having Artificial Intelligence.
Yeah...the natural language advice isn't all that good. I mean, it is good, but it's no better than the lines the engine can already give you. I pretty much always get "absolute pin" and "relative pin" every single time. I dunno. Apparently this is hard. I've never seen it done well even though I know smart people work hard on it.
I've noticed that almost EVERY new chess puzzle has the suggestion "Past Pawns", while this is usually not relevant at all. This must be a bug, or it is major trolling by some "funny" dudes suggesting this for every single puzzle. I always put thumbs down for this, but it really makes me feel annoyed every time I see it over and over again. Please fix this next level trolling now.
