After all the forwards and backwards analysis, at 45 plies I had g5, but then it switched to Rg8.

I am trying to really prove the superiority of g5 over Rg8, but I cannot get a clear answer.
Any opinions?

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

The positions I analyzed came from the following plans, collected from the original thread:

I have these lines stored from latest thread (there was another one last year already, I think) and some analysis of mine:

Re:

For the following position, after I analyzed carefully:

Rg8 has a score of 170 at a depth of 51 plies
g5 has a score of 142 at a depth of 45 plies
Rf7 has a score of 87 at a depth of 42 plies
No other move has a positive score

Because of the discussion about the excellence of the move g5, I analyzed the following positions backwards and forwards several times at ten minutes per position per cycle on a fairly powerful machine (and some for much longer after the hash was loaded with interesting analysis):

After all the forwards and backwards analysis, at 45 plies I had g5, but then it switched to Rg8.

I am trying to really prove the superiority of g5 over Rg8, but I cannot get a clear answer.
Any opinions?

Everything I tried on SF and Lc0 turned into a draw. I could find no win, just better moves for white. If true that would make g5 and Rg8 =.

At a depth of 51, I get a score of +170 for Rg8.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

I have these lines stored from latest thread (there was another one last year already, I think) and some analysis of mine:

Using your stored lines, I found two things of note:

In this position, the opponent's move in your line is Bf1, but Bc2 is much stronger:
acd 43; acs 1410; bm Bc2; c3 "Bf1"; ce -187; pm Bc2; pv Bc2;

In this position, the opponent's move in your line is Nxc7 but Rah1 is much stronger:
acd 44; acs 1410; bm Rah1; c3 "Nxc7"; ce -183; pm Rah1; pv Rah1 Bg5;

With the improved defense, the value of the position is just under two pawns ahead for black, about the same as for Rg8.
All the other moves are optimal for both sides except for much later in the line where it is fully decided either way for black.

I guess I found most of what you found, better moves for white. Nice job on finding the win. I could not find it. Can you post the winning PV?

Both searches give an advantage of about 2 pawns, so I do not think it is clearly a win. It's a $17 or maybe $19 NAG.

My main PC is busy at the moment, Dann, but do you have any lines for your claims?

Attached you will find the raw analysis (from back to front) of your original positions one by one.
It shows each ply of search.

I plan (over the weekend) to analyze both positions (after the pawn move and after the rook move) at 24 hours for a more definite result. (I am speaking of the root position after g5 and Rg8).

I no longer have the raw analysis for the Rook move, which was made some weeks ago.
