4nrqk/R4bbn/1p1pppp1/PKpppp2/7P/1PPPPPPN/2BB2QN/6R1 b - - 0 1 (FEN)

black first to move

Stockfish18+ (Dev. version) eval: -0.5

Description:
Welcome to this CP submission! 
I forgot the openings
This is cool anyways
Have fun testing this!

Status: Declined

Yellow only has one line (which is not very easy to find) to reduce the material disadvantage. 

I tested this a long time before with yx, i would say -1 because the opening is pretty forced and requires accurate play to not get into disadvantage by red

It's a custoom position for arena ahhhh
also red doesn't need accurate play to not get in disadvantage, (for example simply running king works in every lines)

Yeah, red doesn't really need to play accurately, but the opening is pretty damn forced.

:/ okay
may I provide the version after these forced sequences?

Nf2+, Kh5, Bd1+, Kh6, Ng4+, Kg7, Nxh2, hxg3, Nf3, b5
is the blatantly optimal line. If you play even the second best move before that it's at least a mistake.

my analaysis

So is this a testing game or something else

Verdict when

i dont like forced opening, maybe something else? (-0)

-1. Opening is forced + looks like an opp-castling position but only 1 king is in danger.

so this is -2 now?

yes

Testing game is needed before voting

Another issue: The starting move, (Nc7) is hard to find for beginners, and by defenition the first move shouldn't be an only one

I will abstain from voting on all C8’s unless they are actually amazing
