Extremely difficult puzzle that showed up in a game I played

I was analysing a rapid game I played and the computer said on move 15 "missed win!" I don't feel too bad about this one because it was extremely tough to find:

Can any of you solve it?

I tried Rxd5 because cxd Bb5 Kd8 Qxd5 is clearly winning

But playing Bb5 first is very nice. One of those fantasy moves you don't take seriously enough.

And anyway, engine points out after Rxd5 Bxc3 white has an edge but has to be accurate (and it's not instantly winning like Bb5 would be)

If this was on tactics trainer, I think it would be one of the toughest problems out there. Probably 3500+ rating imo.

I don't have much experience with TT, but from what I've seen 3000 puzzles are study-like positions with non-intuitive quiet moves. Bb5 is a pretty move, but not very surprising. Sure it would have a high rating, but I don't think it would be that high.

The second move is harder to find than the first move, because Bxe7 is the obvious move and winning. Bb5 is easy to find if this is a puzzle, but in a game you may not expect it.
