Chess is a combination of the science of making accurate moves, and the art of making the opponent to make inaccurate moves.
The five most remarkable players in chess history:
1. Paul Morphy
2. Emanuel Lasker
3. Jose Raul Capablanca
4. Robert James Fischer
5. Garry Kasparov

My homepage, dedicated to analyzing the level of chess play of various chessplayers:
http://www.chessanalysis.ee/chessan...
I'm currently doing an analysis study, where I compare roughly 2650-rated players according to chessmetrics elo rating throughout the history of chess. The aim is to find which level of play corresponds to a certain rating in different decades.
The latest version is available here:
http://www.chessanalysis.ee/Quality...
The methods are as follows:
I analyze games between 2600-2700-rated players. Moves by both sides are subject of the analysis. Results are displayed by decades from 1860s till 2000s. Plus, I also analyze games by 2000-2700-rated players after each 100 points from 2008 for comparisons.
The games are randomly chosen from the decades.
The start point of the analysis of every game depends on a period: 1860s-70s 8-th move, 1880s-90s 9-th, 1900s-10s 10-th, 1920s-30s 11-th, 1940s-50s 12th, 1960s-70s 13th, 1980s-90s 14th and 2000s 15th move.
The minimal length of a game is 20 moves + the start point; depending on a period it may vary from 28 to 35.
The maximum length of games is unlimited. Positions with fewer than 10 pieces are not taken into account, except blunders.
Rybka 3 Default with default settings is used for the purpose of the analysis. The time per position was 5 minutes on an older computer. Now it's 65 seconds per move.
Moves outside [-2; 2] interval are discarded.
The maximum value for an error is 4.00.
A separate engine is used to calculate the complexity of positions, Stockfish 14. The complexity of a position is determined from depths 2 to 15 and by adding differences between the eval of the best and the second best moves each time Stockfish 14 finds a new move. Differences found on the depths 10-15 are multiplied by 2.

Dec-06-21 E Williams vs Staunton, 1851

nimh: My first reaction on seeing this was like "A Williams game?! Surely, it can't be a coincidence!" But it likely is

Nov-06-21 Iivo Nei

nimh: <Palju õnne tema 90. juubelil, Iivo Nei.> I'm sure he'd be glad to know that someone far far away congratulates him. But correct would be "Palju õnne tema 90. juubeli<ks>. The transitive case instead of the adessive.

May-29-21 Wilhelm Steinitz

nimh: <then find a few more words, please!> The most inferior among them? On absolute level he sure is due to rising level of play but in terms of greatness or superiority to contemporaries you can easily name several ones in turn inferior to him.

Feb-06-21 Jeremy Lim

nimh: <FVCK TOM BRADY!> Well, you definitely need to be an attractive woman, in the first place...

Feb-07-20 Paul Keres

nimh: The statue at the previous location was indeed easy to miss walking on the street. Trees were around it and the monument itself several meters away from the sidewalk.

Jun-02-19 Norway Chess (2019)

nimh: <JimNorCal: Is it Finnish and Magyar which form a group unto themselves?> Yes, both are members of Finno-Ugric family which itself is a subfamily of the Uralic language family. But this distinction is quite broad, those languages you mentioned (along with Estonian, a close ...

May-01-19 Jeremy Lim

nimh: <For example, Steve Kerr is the all-time leader in shooting pct. on threes, at 45%. But no way is he close to the best shooter. He only shot when wide open, when Jordan or Pippen or Duncan drew the defense and kicked out to him.> And what type was Drazen Petrovic with his .437, ...

Mar-03-19 Kaido Kulaots

nimh: Just reversion to the mean at work.

Feb-23-19 Aeroflot Open (2019)

nimh: And down goes Dubov! Three wins with black over Maghsoodloo, Firouzja and Dubov is an incredible achievement, and if the Estonian GM can avoid losing in the next rounds it will surely be his best tournament of the life.

Feb-05-18 Emanuel Lasker

nimh: Estonian has 'Saksamaa' and Finnish has 'Saksa' - it clearly originates from the words 'Saxony' and 'Saxon'.
