I’m failing to understand the lichess.org practice exercise ‘Exploit the Pin
#3’. I’ve arrived at the ‘correct’ move (Nxg5), but without any understanding of where there is a pin, and how it has been exploited. Can someone please enlighten me?

    Ah, thank you, I think I see now. If black knight takes g5, then black loses both rooks while white loses only one. Overall, white gains the pawn and a rook.

    I think I was confused that black’s response of Ng7 moved off the pinned file and so seemed to ignore the pin. Now I see that by moving to defend the e8 rook it ensures all rooks are exchanged and so limits white’s gain to only the pawn.
