I've just finished one party against StockFish and when I've asked the computer analysis, it gives me a continuation I can't understand.
Could someone explain me why analysis proposes that?

After Ref1, analysis says is one inaccuracy (ok, I can agree with that) however, in the continuation, he proposes 20. Be2 Nxc5?
Why Nxc5? What is wrong with Nc7? Why analysis propose that sacrifice? Ok, you win 2 pawns, but it really worth to sacrifice the knight now?
