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?

    Another beginner here but I think the pin in this case is the knight on e6 pinned to the rook e8. If that black’s knight moves to take g5 then the exchanges end up with white losing both rooks.

      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.
