why is this position completely lost for white?

i need some help with this position. ive been analyzing the italian and i dont understand why lichess says this position is -8

i dont see the win, and i would appreciate it if people commented
  

It appears from the Stockfish lines, it is making use of the open files, open diagonals with LSB and DSB, whereas white doesn't have an open file to work with until after tempo loss and only one bishop. Before I looked at the Stockfish lines in depth (no pun intended), I was thinking of an attack on the kingside. After looking at Stockfish lines with an attack, I see one straight from Stockfish (without choosing the path) for white where it gets punished, and then one with black that might occur I think after I chose certain moves. Those sequences went: 13. O-O (13. Nc3 Bb4 14. O-O O-O 15. d3 Bxc3 16. bxc3 Rd8 17. Bxh6 (17. c4 exd3 18. cxd3 Qe5 19. d4) 17... gxh6 18. Qc1 Qh5 19. Qf4 Qg6 20. f3 exd3) 13... Bd6 14. Nc3 O-O 15. d3 Bg4 16. Qe1 Qh5 17. h3 Bxh3

I tried to make pragmatic moves, castle, knight before bishop, etc... and it landed on 17...Bxh3!. This is the part: 13. O-O Bd6 14. Nc3 O-O 15. d3 Bg4 16. Qe1 Qh5 17. h3 Bxh3

Is this a trick question?

We don’t need stock fish to literally see black is better.

And we don't need mind readers. People who come off assuming don't know how to communicate the whys. But they will tell you they know the whats to hide their insecurities.

Would you want the black or white pieces in that position?

I would want you to contribute thought. I would want you to give a sequence you like. If the answer is SO obvious to you, tell us a sequence of moves YOU would do.

Black's pieces are out in the open playing, while White's pieces are inside (probably playing League of Legends). Whose pieces are more active?

.\

a piece for 2 pawns

also lichess says its -8 and im asking why

Black is simply a piece up are you dumb or something?

Activity and piece up. It's common sense that black is way ahead

Keep in mind that Chess.com gives the position a -2.73

At what depth? You have to let it calculate longer.

White has two pawns for the piece, but this those pawns are pretty much worthless now. They don't control any important squares and they are a long, long way from queening. For the moment, Black is simply a whole piece ahead. Black is also way ahead in development, with plenty of active pieces and open lines for his pieces. . White will go to his grave clinging to those two pawns

11 feet

It's a lot like asking "why is a queen better than a rook. I don't see a tactic."

The queen is better because it's more mobile. Loose pieces, weak pawns, weak king, these things always exist eventually, and when they do, the mobile pieces are likely to have tactics available.

Play the position against yourself multiple times, then play it against the engine multiple times, then against yourself multiple times etc... until you're convinced.

That's not enough.

By the way, the NNUE engines sometimes give enormous evals like that... they're a bit too high, at least compared to what I'm used to seeing.

Don't think of it as "black has a forced win." Try to understand some practical elements (like all of black's pieces will be more mobile for the foreseeable future). And when looking at lines, play the moves YOU want to play. If the advantage drops from 8 to 5 that's completely meaningless. Black is still far ahead, your move was good.

As long as you can play moves you like while keeping a winning position then it's good.

I'm not convinced it does evaluate to -8. Stockfish at depth 20 gives it -3.7 which at infinite depth almost certainly maps to Checkmate for Black but what depth do you need to use to get -8?
