PostSubject: How strong can the smartest chess engine in the world play intuitive chess?   How strong can the smartest chess engine in the world play intuitive chess? EmptySun Jan 08, 2023 11:59 pm

Intuitive chess is where the chess engine decides on a move with no calculation. But plays based on positional understanding only.
Lc0 is by far the smartest chess engine I have tested. With this kind of play.

Lc0 vs Stockfish at intuitive chess. Lc0 wins 100% of the games.

I define intuitive chess as setting the chess engines to play a move at only 1 node.

When playing a match of 50 games. Lc0 was able to score 2 draws with just intuitive chess play. Against Stockfish DEV playing with at time control of 1m+1s.

And Lc0 was able to score a accuracy of .45 centipawns in the 50 games playing against Stockfish DEV. A accuracy just below GM level of play at 3 minutes a move at .40. And Lc0 is doing so with zero tactical calculation or look ahead.

Lc0 v0.29.0:   53/55/24/72/48/65/56/37/48/55/81/83/28/36/23/55/50/80/54/41/45/33/53/82/49/58/40/49/42/34/30/4/69/28/38/26/20/23/40/27/69/18/4/37/27/38/32/1/69/45  => Average=0.45

Here is the accuracy score of GM Magnus Carlsen last 50 bullets games played at 1m+1s on Chess.com. And GM Carlsen is achieving this accuracy with 2 mins of thinking time in a 60 move bullet game.

MagnusCarlsen:   60/54/68/51/44/71/38/29/55/49/28/27/68/31/51/77/25/23/69/18/54/57/20/28/49/11/29/47/58/16/33/16/59/26/8/25/14/10/11/18/8/6/39/20/42/14/24/37/13/14  => Average=0.38

Here are some other scores that were GM Magnus Carlsen's opponents at 1m+1s time controls.

Hikaru:   68/63/12/55/16/8/20/42/37  => Average=0.38
Duhless:   55/28/49/51/12/76/25/55/37/63/11/65/12/23/14/75/61  => Average=0.41
LyonBeast:   56/34/23/8/86/35/35/84  => Average=0.43
FabianoCaruana:   74/46/31/30/46/93/71/8/25/47  => Average=0.50
NikoTheodorou:   70/46/71/42/71/114  => Average=0.66

It is amazing that chess can be played at this level by just looking at the chess position. And it is very depressing for us human chess players. Who thought we knew more about positional understanding then the chess engine. And that is true, except for Lc0.

Here is Lc0's 2 draws playing Stockfish with intuitive play vs. Stockfish DEV playing with 1m+1s on 16 CPU's.

I strongly approve of this testing: IMO "knowing" is more intelligent than "calculating".

I like learning new things about chess and chess engines.. And to do this you have to push the chess engines. And do crazy types of testing.

I never would have guessed you could play chess well enough to draw Stockfish with zero calculation. Or play chess at this type of strength. With just positional understanding.

I am not buying it totally. As if you know your opponent is not calculating. You would change your playing style. But clearly Lc0 can play chess at some type of master level. With zero look ahead and just with positional understanding.
