A Subtle Miss

Hi everyone, and welcome to my new post!  Here is the position we will be analyzing today.

Black to play, White just played Rg4-Rg6. We are in trouble. We're down one pawn, and probably will be more, and I will be helpless once the b5-pawn and a4-pawn run up the board. I played 46... Nd2+, hoping for something out of nothing. Feel free to take the position above as a tactics trainer... rated, ohh, I don't know, you discuss in the comments!

I hope you enjoyed the post... I ended up losing the game of course!  Have a wonderful day, and I will see you all next time!
