0. Blueprint

Spend sixty percent of your time on endgame and middle game, leaving forty percent for openings. Focus on a few openings that are inherently sound structurally, are not as dependent on move order, and where there is less memorization required. As White, consider the London System. As Black, pick a response to 1.e4 (e.g., Petrov Defense, Caro-Kann Defense, French Defense, Pirc) and something for 1.d4 (e.g., Slav Defense, King's Indian Defense).

2. The Endgame

Daniel Rensch advises: (a) master the basic checkmates, (b) master the basics of technique, (c) push the passed pawn, (d) activate your king, (e) play backwards-to-forwards chess, (f) beware "German words", (g) find and use the pawn majority, (h) use the principle of two weaknesses, (i) be concrete and calculate, (j) FEWER PIECES = LESS ROOM FOR ERROR!

C. Knight + Bishop

Some experts consider this capability not the best use of your time, as you are unlikely to confront this need. On the other hand, it's very satisfying--more than seems rational--to know it. There are three phases. First, learn the checkmate when you have the opponent's King limited to two squares in the same-colored-corner as your bishop. Next, learn to force the opponent's King, limited to the back rank, from the different-colored-corner as your bishop to the same-colored-corner as your bishop. Finally, learn how to force the opponent's King from any square on the board to a different-colored-corner than your bishop.

3. The Middle Game

Important middle game principles include: (a) centralize your pieces, (b) trade your flank pawns for your central pawns, (c) avoid pawn weaknesses, (d) avoid creating weak squares in your position, (e) always blockade your opponent’s isolated pawn with a knight, (f) 0ccupy open files with your rooks, and (g) keep the bishop pair, according to thechessworld.com.

4. Opening Principles

You advantage going into the middle game will primarily be the result of your optimization of opening principles, including: (a) the principle of harmony, (b) the principle of the center, (c) king safety, (d) the principle of development, (e) the principle of time, (f) taking the initiative, and (g) weakening the opponent's king defense.

7. Semi-Open Games

A semi-open game is an opening in which White plays 1.e4 and Black breaks symmetry immediately by replying with a move other than 1...e5.

The Sicilian Defense

1.e4 c5 is well established. The dragon variation is the best for beginners, according to Rozman, who suggests avoiding the defense totally until you have a 2000 ranking.

The Stonewall Attack

1.d4 d5 2.e3 is a good Queen's Pawn opening for beginners, according to Gotham Chess (GM Levy Rozman).

The Catalan Opening

Rozman also endorses the Catalan Opening for advanced players, where White adopts a combination of the Queen's Gambit and Réti Opening.

10. Flank Openings

A flank opening is typified by play on one or both flanks, the portion of the chess board outside the central d and e files.

A. The English Opening

1.c4 is the fourth most popular opening and is considered reliable and flexible. White begins the fight for the centre by staking a claim to the d5-square from the wing, in hypermodern style. This opening is often used as a transpositional device in much the same way as 1.Nf3 - to avoid such highly regarded responses to 1.d4 as the Nimzo-Indian and Grünfeld Defense.

11. Indian Defenses

Indian Defenses take the form 1.e4 Nf6. Whereas classical defenses fight for initial center control using pawns (e.g., 1.e4 e5), hypermodern openings such as the Indian Defenses fight for initial central control using pieces.

The Nimzo-Indian Defense

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 is a highly regarded response to 1.d4.

The King's Indian Setup

This is a good general approach playing as White or Black, and the best defense for beginners, according to Rozman. Naroditsky advises players to wait until they reach 1600 to use this opening.

The Trompowsky Attack

Rozman advises advanced players to consider the Trompowsky Attack (aka Ruth Opening aka The Zot), where White sidesteps immense bodies of opening theory of various Indian defenses like the Queen's Indian, King's Indian, Nimzo-Indian, as well as the Grünfeld Defence.

17. Academic Findings

Researchers found: (a) a strong correlation between chess skill and number of hours of practice; (b) group practice was a better predictor of high-level performance than individual practice; (c) masters had a higher chess rating than expert players after only three years of serious dedication to chess, although there were no differences in the number of hours of practice. The difference that may explain the variation in rating is that masters start practising at an earlier age than experts. (d) Activities such as reading books and using computer software (game databases, but not playing programs) were important for the development of high-level performance.
