Why is this position -2 in black's favor?

I'm the one who came up with the philosophical "Pedestrian/Cyclist Theorem," so I decide who is better.

That face means victory.

After cxd4 and cxd4 and Qc7 then Black has some targets to attack.

b1z I am not as good as you at chess...

But I would say that there are positional weaknesses in white's position. 

Possible ng4 trying ne3, mostly positional stuff

hope this helped b1z

Positional is such a boring and big word.

Just say, "relating to position." 

Weak e4 square, more weaknesses on the kingside, and white has grave problems completing his development.

not really 

I think development is the problem for white. Because the pawn is on c3, the knight cant naturally develop there, so the bishop has to leave first. the problem is that f5 is blocking the bishop from having an active role. so if you fix that with f5 for instance, white's king is also still in the center and it'll take at least 3 - 4 more moves for white to get settled. just my opinion.

You are a far stronger player than I am.  That said, I'd have to guess piece coordination and development.  

Because you've gotten your king out of danger and are ready to put your rook on the open file, which pins the knight to the king

Ng4 seems to be a recurring theme after I played around with the position with stockfissh.

     After 8....0-0, white needs to play 9.h3 or the pinned knight will be in a lot of trouble. Then with  Re8, Qe7, and c4 (or cxd5 cxd5 Nxd5) black puts tremendous pressure on the knight on e2, winning the d pawn and/or perhaps the f pawn--depending how white defends--while maintaining an initiative and greater activity.

Hmm that’s seems plausible 

yes im literally right ha

White knight and bishop are horrible

Why did you bump

They didn't. They shoved.
