Yet another borderline position

Another full point, Brainfish White Contempt -20, CFish Black +20.

You're using syzygy 6 right.

Try contempt = zero for both parties.

[peter]

No, Jon, it's your turn again.

Try to find a white blunder in the game above, if you don't find any, the case is closed to me.
If you do, show your next drawn line or game from your deviation onwards.

Problem is, you cannot take a proving output- line backward further then to about tenth move, so proving win or draw might be a matter of personal pov, mine is Black wins.

Pity, found one by myself again, 11.b4 instead of Nf3:

If I only could.

In this one line at least 16...Bd1 gives away a clear black winning eval. After 16...Bb5 instead: (starting with hash full from backward):

Now I still have to check 9.Bc3 instead of Ba5, which allows the black Rook to get to 2nd rank.
If I come to a conclusion about that too, I hope I'll have my opinion made up finally again.

[Nordlandia]

Peter Martan: without handicapping black side, it's hardly a draw. Now do you mind if we switch position to the following: [d]r5k1/pb3p2/1p2p1p1/3n3p/3P3P/P7/1P1B1PP1/R3R1K1 b - - 0

In the meantime I yet got stuck with Black after 9.Bc3 again:

Let's leave it for good, White can build up a fortress again and again and I simply can't tell if Black can deny that with perfect play.

Changing to your new position soon, but will need some time in between for other things right now.

Indeed there doesn't seem to be much progress in engine's output. (At least not in the first 20 moves of any of the lines below.)

16MV in depth 51 with full Syzygys after 1...a5 (which transposes to some other first black moves sooner or later e.g. to 1...Kf8 ):
