Interesting position - LC0 failure

Post by Guenther »

In this opening, which should favour White quite a bit, LC0 managed even to lose with very good hardware.
(It is also surprising that depth broke down to 17 despite using 111 seconds - RTX 2080

I would be interested in analysis from a RTX 2080 (or similar) especially for move 22. f4? (which seems to lose IMHO). Louis Zulli?
Best would be analysing when feeding the game in analysis mode and comparing to the FEN output for the exact position.

BTW according to SF in that game most of the advantage already was gone with 11. Nge2, but I still think the game should
be drawish before 22. f4.

... forgot to mention that I would prefer the usage of a late 428xx net for comparison ;-)

Not quite the method you requested, but I had Lc0 (network 42850) search several positions prior to the one in question. And for that position, here's the result. Note that f3f4 appears briefly at depth 17-18.

(It is also surprising that depth broke down to 17 despite using 111 seconds - RTX 2080

I would be interested in analysis from a RTX 2080 (or similar) especially for move 22. f4? (which seems to lose IMHO). Louis Zulli?
Best would be analysing when feeding the game in analysis mode and comparing to the FEN output for the exact position.
Not quite the method you requested, but I had Lc0 (network 42850) search several positions prior to the one in question. And for that position, here's the result. Note that f3f4 appears briefly at depth 17-18.

Thanks a lot Louis! So you leave depth 17 already at around 77 seconds, while the original user still had depth 17 in 111 seconds.
Well, somehow I had expected this after all the crazy things he did with his super duper hardware - you sure can guess who ;-)
(there are really some crazy depth to time hickups in the finally first released pgn after myriads of plain youtube links)

(It is also surprising that depth broke down to 17 despite using 111 seconds - RTX 2080

I would be interested in analysis from a RTX 2080 (or similar) especially for move 22. f4? (which seems to lose IMHO). Louis Zulli?
Best would be analysing when feeding the game in analysis mode and comparing to the FEN output for the exact position.
Not quite the method you requested, but I had Lc0 (network 42850) search several positions prior to the one in question. And for that position, here's the result. Note that f3f4 appears briefly at depth 17-18.

Thanks a lot Louis! So you leave depth 17 already at around 77 seconds, while the original user still had depth 17 in 111 seconds.
Well, somehow I had expected this after all the crazy things he did with his super duper hardware - you sure can guess who ;-)
(there are really some crazy depth to time hickups in the finally first released pgn after myriads of plain youtube links)
Ah, you are still following his posts? I don't have an ignore list, I just try to remember some names or nicknames.

(It is also surprising that depth broke down to 17 despite using 111 seconds - RTX 2080

I would be interested in analysis from a RTX 2080 (or similar) especially for move 22. f4? (which seems to lose IMHO). Louis Zulli?
Best would be analysing when feeding the game in analysis mode and comparing to the FEN output for the exact position.

BTW according to SF in that game most of the advantage already was gone with 11. Nge2, but I still think the game should
be drawish before 22. f4.

Not quite the method you requested, but I had Lc0 (network 42850) search several positions prior to the one in question. And for that position, here's the result. Note that f3f4 appears briefly at depth 17-18.

Thanks a lot Louis! So you leave depth 17 already at around 77 seconds, while the original user still had depth 17 in 111 seconds.
Well, somehow I had expected this after all the crazy things he did with his super duper hardware - you sure can guess who ;-)

I guess some subject matter experts do not know how Lc0 works in a game. I will make this short. And why you can not take a fen from a game, and compare the analysis running Lc0 from a cold position. To the game analysis without seeing "crazy depth and time hickups".

Because Lc0 stores positions from the previous moves. And Lc0 uses them in the search. :roll:

A quick example, and you can see this in the videos.


In this position Lc0 guessed Stockfish move of g6. And the depth starting the search is already a depth 14/30 with 15290Kn searched in 9 seconds.
Nps is 52kn/s. But with the stored positions we have a total of 15290Kn not 468Kn like in a cold search. This is like Lc0 running at 1,699 Kn/s

That's really exciting news for us :)

Seems you cannot read properly. I quote it again for you, as I suggested to do two ways of analysing and compare both results,
which should show 'hot' and 'cold' analysis (to stay in your terminology - we call it with and w/o filled relevant hash entries).
You also abviously missed the part, where Louis filled the hash with previous moves (but not the whole game though).
Best would be analysing when feeding the game in analysis mode and comparing to the FEN output for the exact position.

I read just fine. Making up lies is a way of life for you. And I will just keep feeding you more rope.... :lol:
