Right, it took 45 minutes and depth 46 to give Bd5 100cps.
Certainly, until depth 45, Nd5 was best choice, right?

Again, with similar strength, SF will miss to win all similar positions in TCEC.

Thank you very much, Andreas, but neither you, nor Bram can convince me SF really sees most of these test positions.

What if it were part of a suite of 100 positions that should be solved in 100 minutes?

SF's score on Fischer's positional suite would be somewhere 12/100, right?

"Much to learn SF still has." - Yoda would say.

This is just to show how much analytical effort has gone into developing the right strategies to overpower the top engines.
With each move consistently analysed for half an hour, and Stockfish using 16 threads, the amount of knowledge one gets from similar sessions is certainly tremendous.

And that is only one of maybe more than a thousand similar analytical threads on talkchess during the last 5 years.

Some might try to raise cheating allegations against me, but I am worth

Where's the complete game of your Qf6+ game, that's brilliant but I also saw a game 10 years earlier (2004) than yours (2014) doing the same mating attack.

Before the Qf6+ sac of Henrikas.

edit: I tried your Fischer positions above, SF8 dev finds h4 as best (7 secs on my old machine), and on another position Nikolic
lost because he allowed Bxf4 when Nh3 could give slight plus for white according to SF8
dev. So Bg4 was not considered as best by SF8 dev because there are refutations. In short,
all positions you posted above is easy for SF8 dev on my archaic 32 bit machine running only at
2.0 GHz.
You are mostly talking BS, as usual.

1. in Nikolic-Fischer, Bg4 is a proven best move, Andrew already posted about it a whole thread on the main forum 2 years ago or so, Bg4 is winning, no doubt about it, and it ONLY confirms the validity of my chess knowledge concept, twice backward shelter pawn on f2/c2; what SF considers as REFUTATION on your computer is completely off the point, SF can see nothing in this position, as it is very deep
2. in the other position, SF might see h4 by a miracle on your computer, but what is the score? On my computer, SF does not pick it easily.
3. Asauskas played a great game, but then Malisauskas played very weak...:); well, just the pattern is the same, twice backward shelter pawn on f7, but the game itself and the key position is very shallow and dull, don't you agree, mate in 5 or so, every engine will see, even Skipper? You can't compare my position, which is much deeper, mate in 20 or so, and much more beautiful, and which neither top engines sees, with this one, can you?; if you mean I copy-pasted it, it is the first time I see this game :)

Concenring my game with SF, no full record, it started a bit later into the game, please read the whole thread, should I read it instead for you.
I am talking BS? You're funny.

First, I am still waiting for the complete PGN of your amazing Qf6
combination, since I already caught you lying more than 3 times without
even a single apology from you. Why lie just to prove a point?
This is just a chess engine forum with nothing to prove here.

I can also post something like this:
[d]N2r4/1k3p1p/3p2p1/3p1p2/1P1B4/bPqpP1P1/P4P2/RK1Q4 b - - 0 1

And claim I can win easily with QxB and all engines are blind on this
Q sac combination, and take credit that I am stronger than any engines on
the planet. But of course this is just a modified test suite to
fit my argument. Seems like this is what you did. (If you CAN NOT post the complete game of your above Qf6! brilliancy, then I will doubt your credibility, due to a dozen lies of you posted on other threads)
Please prove the authenticity of that game by posting the complete game
and the engine version you used so I can check and verify.

1.Your first point, yes, Bg4 is dubious according to SF latest dev version and there are other
stronger winning moves. I already told you, that after Nh3, there is no way black can proceed a win according to SF, otherwise you can prove me wrong if you can post the winning line.

2. Your second point,, the move h4 in latest SF dev is the only positive score given by SF dev,
I don't lie like what you're always doing, where you even modify a PV intentionally and then conveniently escape by claiming your engine is buggy and it displayed wrong PV.
Here: Image
Does that satisfy you? Because no other moves are better than h4, doesn't matter what engine score is on this move.
Because no other better alternative in a Multi-PV.
To think this is just 7 seconds on a 10 year old 32bit machine, using a 32bit SF8 dev.

3.No you are caught lying for the 4th time, Qf6 done by Asauskas is difficult for current engines. You just modified a difficult test suite and claim you have beaten an engine to prove your point that you're stronger
than any engines.
Concenring my game with SF, no full record, it started a bit later into the game, please read the whole thread, should I read it instead for you.

This is your 5th lie, because you can even remember the winning
combination because this game is very special, and yet you can't
remember the whole game? LOL even a 1200 player can remember the
complete game by heart of his amazing combinations. I can remember
complete games (more than 30) of my combinations and amazing sacrifices since grade school.

You EVEN CLAIMED THE GAME WAS LIVE, isn't it? Now you can't trace your online LIVE game done in talkchess? Even if it is not live, you can still remember it, because you claimed you are 2100+ in strength. 5th lie.
I also do not believe him but 2100+ players do not always remember their games.

Note that I will never believe people who claim that they are 3000 under quiet conditions when they do not play in tournaments against humans.

Players that is 3000 under quiet conditions can get easily the GM title and I do not believe people who even do not try and claim they are strong.

White to play and win, single winning move.
This is from Fischer-Rossetto, Mar del Plata 1959.

Anyone able to find it?

Engines are reputed to be very good in the endgame, due to diminishing number of lines.
Do the 64/16 cores see it?
This is yet another not winning position Lyudmil
Black has a refutation and this time also easy to find with your 4cpu PC

Lyudmil is a complete liar. These phonies who believe that they are even remotely close to today's strongest engines are simply idiots. It's like saying that you could race the world's fastest sports car with a horse. This guy never stops. Let's see how strong Lyudmil really is. Go play a Super GM Lyudmil. Go play in super-strong tournaments if you have such superior chess skills. People like you are more delusional and arrogant than Trump himself. You are not even ten percent of what Stockfish is. You have no place, and absolutely no right even believing that you belong in that same sentence with Stockfish.

You are nothing more than child's play to these super-strong engines.

Lyudmil and ARB should be tag-team buddies; they thrive in their own fantasies.
