Fortress vs Stockfish 11

I had this game against Stockfish where i managed a draw with Black by creating an impregnable fortress. Hopefully it will serve as a good example of fortress for the chess community hence posting it.

Comments and feedback are most welcome.

6.Nf3 is not a stockfish move

10.Re1 is not a stockfish move

I stopped checking there.

What was the depth?

30.

More importantly, on move 15 stockfish likes black (-0.50) so obviously white was not stockfish because stockfish doesn't like white on move 15.

Here's one at a higher depth since I know you like that

Move 17 it prefers taking with the rook.

This is also far enough into the game you can't excuse it with a bad opening book.

(and I didn't let it run until it liked Rx. It preferred capturing with the rook from the beginning)

Yeah, it's actually a fun fortress against something that was probably an engine.

It seems that everyone lately has been able to get a result against Stockfish. The poor thing has suffered enough losing to that Cpu girl. Be nice and let it beat you once in a while or it might contemplate eSuicide otherwise.

Speaking of stockfish

Stockfish is slowly getting behind in the championship- take a look at the latest games

-Lc0 is even winning with black!

Ratings are more accurate than titles.

That's great bro!

I know another four members who won or drew vs Stockfish and Komodo 11.

Don't pay attention to envious people, they can't prove their lies. What you have done is incredible! You are great!

Keep up the good work!

Are you saying I can't prove my... screenshot?

It's a screenshot, and anyone with access to stockfish 11 (which is everyone) can verify it.

Anyway, I already said it was a nice fortress against an opponent who was probably some kind of engine.

When I said envious people I wasn't referring to you, I was talking about people in general. Possible people that might come into this forum later, I don't know who will they be.

Stockfish makes different moves each time. It doesn't always choose the same move.

Your hardware, configuration and Stockfish version are different than those in the game of the OP.

57 deep moves configuration is counterproductive, Stockfish in your machine is thinking wrong moves.

I have no idea what that is. My screenshot was at depth 36 and took about 1 minute.

It doesn't matter if the moves are good or bad, it only matters if the moves are stockfish's moves. That's the only way to verify whether white was stockfish.

It's so interesting that stockfish is starting to lose vs Lc0 at the same time is starting to get draws or losing vs humans.

Maybe there really was a Ghost in the Shell.

36/57 means that in one minute it has being able to reach depth 36 out of 57 depth configuration. That configuration (too much depth) is counterproductive, is making wrong moves. From 20 to 25 depth is the best configuration so that the computer doesn't get lost in the forest of possibilities.

If you leave it to think a whole day could be able to reach 57 depth (57/57), but still a wrong move.

From a given chess position there are as many posibilities as atoms in the visible universe. There is not a computer on planet Earth able to come up with the best move given a position, that engine must have infinite elo points, that doesn't exist. That's something that only a human could reach (one with a soul).

Humans can't reach infinite elo points either.

That search depth happens when you don't touch Arena default configuration:

To adjust maximum depth: click on "Fixed search depth".

But anyways the engine could suggest different move when playing than when analyzing. Depending on many other things, like for example GUI that's running the engine, configuration in that GUI, etc.

Same stockfish file downloaded installed in droidfish and chessX I have different move suggestions than in Arena or Lucas Chess.

The elo of humans varies depending on the day. I analyzed Magnus Carlsen vs Fabiano Caruana. Looking at Lucass Chess elo points analysis I have checked that some games they reach 2880 elo points, sometimes 3200... sometimes 2700...

A human that ponders a position for weeks could reach higher elo points than a machine (for that particular position). He could do the same for the rest of the match and at the end some months later produce better moves than a machine.

We don't know if a human has reached infinite elo points for a match or a position, because we need an infinite elo points machine to compare his moves. But it is possible, why not?

1 min of analysis of Stockfish 5 Mnps on 4 cores is approx 3500, which is enough for practical use.

Insta move of SF ( force move with 30 ms thinking time) is 2500 elo

0.1 sec= 3000 elo

1 sec = 3200 elo

1 min = 3500 elo

1 hour = 3600-3650 elo
