The question is if 70 plies from 2018 are better than 60 plies from 2022
I am not sure.

I also expect different analysis if you run 60 plies again today.
Not sure even if the first move is going to be the same.

[Dann Corbit]

I replaced the70 ply search in my database with the 60 ply search I just made.
I am re-running the four most important first moves at 70 plies.
So far, I have this:

If you ran a 60 ply search a month ago, SF picked a knight move for the opening position. I never saw that before.
This was the pv:
Nf3 Nf6 c4 e6 g3 d5 Bg2 dxc4 Qa4+ Bd7 Qxc4 c5 Ne5 Qc8 Nxd7 Qxd7 O-O Nc6 Nc3 Be7 b3 O-O Rd1 Rac8 Bb2 a6 Qa4 Rfd8 d3 h5 Qh4 b5 Rac1 Nd4 e3 Nc6 Bf1 Nb4 Qh3 g6 Be2 Qa7 Qg2 Qb6 Ba1 Nc6 Ne4 Nxe4 Qxe4 Bf8 a3 Bg7 Bxg7 Kxg7

I replaced the70 ply search in my database with the 60 ply search I just made.
I am re-running the four most important first moves at 70 plies.
So far, I have this:

If you ran a 60 ply search a month ago, SF picked a knight move for the opening position. I never saw that before.
This was the pv:
Nf3 Nf6 c4 e6 g3 d5 Bg2 dxc4 Qa4+ Bd7 Qxc4 c5 Ne5 Qc8 Nxd7 Qxd7 O-O Nc6 Nc3 Be7 b3 O-O Rd1 Rac8 Bb2 a6 Qa4 Rfd8 d3 h5 Qh4 b5 Rac1 Nd4 e3 Nc6 Bf1 Nb4 Qh3 g6 Be2 Qa7 Qg2 Qb6 Ba1 Nc6 Ne4 Nxe4 Qxe4 Bf8 a3 Bg7 Bxg7 Kxg7

Assuming you use more than a single core I expect different lines at depth 60 even if you use the same SF and I will not be surprised by a different first move.

You probably can build some big opening book only by running the opening position to depth 60
10 times and add the moves that stockfish suggest to the opening book and later do the same for every position in the opening book at ply 1 and later do the same for every position in the opening book at ply 2 and continue in this way.

Depth 60 is a very big depth so it is going to take a lot of time but it may be nice to have some interface to do it for a specific depth and every engine that you choose that is not deterministic (because of using more than one core or because of different reasons) when there may be 2 options (one with clearing hash between searches and one without clearing hash between searches).

It may be interesting to compare the size of the opening book when you generate them in this way(for example if you decide depth 10 and ply 10 or if you decide depth 20 and ply 10).

[Dann Corbit]

The knight move astonished me, so I did it twice at 60 plies.
I did get a different reply to the knight move:
First pv:
Nf3 d5 g3 g6 d4 Bg7 Bg2 Nf6 c4 c6 b3 dxc4 bxc4 c5 O-O O-O e3 Nc6 Bb2 cxd4 exd4 Ne4 Qe2 Nd6 Nbd2 Nf5 Nb3 Nfxd4 Nfxd4 Nxd4 Bxd4 Bxd4 Rad1 e5 Rfe1 Be6 Bxb7 Rb8 Nxd4 exd4 Bd5 Bxd5 Rxd4 Bxc4 Qxc4 Qb6 Rf4 Qb7 Qe4 Qxe4 Rexe4 Rb1+ Kg2 Rb7 h3 Rd8 Re5 Rd2 Ra4
Second pv:
Nf3 Nf6 c4 e6 g3 d5 Bg2 dxc4 Qa4+ Bd7 Qxc4 c5 Ne5 Qc8 Nxd7 Qxd7 O-O Nc6 Nc3 Be7 b3 O-O Rd1 Rac8 Bb2 a6 Qa4 Rfd8 d3 h5 Qh4 b5 Rac1 Nd4 e3 Nc6 Bf1 Nb4 Qh3 g6 Be2 Qa7 Qg2 Qb6 Ba1 Nc6 Ne4 Nxe4 Qxe4 Bf8 a3 Bg7 Bxg7 Kxg7

It is very rare to get different first moves from SF after a long search unless they are permutations.

It is very rare to get different first moves from SF after a long search unless they are permutations.

I see that already the second move is already different so I doubt if it is very rare to get a different first move.

I find different moves with 7 cores at depth 34 from the opening position and I see no reason to have a different picture with a longer search.

Did you clear the hash between searches?

Yes
