0-1000 Player has just learned the game, they constantly leave pieces en prise, and make many blunders. Player has no tactical, endgame, or positional knowledge. Absolutely No evaluation or analytical skills.
1000-1100 Beginning player now has several games under their belt. They have very basic tactical knowledge and they continue to make blunders and to leave pieces en prise. Plays without plan.
1100-1200 Beginning player continues to make many blunders. At this level they have learned basic tactics. Occasionally leaves pieces en prise, but this is not a common occurrence. Sometimes plays with a plan, but the plan is usually incorrect. At this point the player sees many offensive tactics but they miss most defensive tactics.
1200-1300 Player begins to understand that chess is a two player game, and begins to ask what the opponent’s last move is threatening. Blunders still occur but less frequently. One major reason for their rating increase, is that player stops leaving pieces en prise. Player has intermediate tactical skills but still misses many defensive tactical shots. Starts to build an opening repertoire, which gets them into the middlegame with a better position. Very limited endgame and positional skills. Starts making better plans due to limited endgame and positional knowledge.
1300-1400 Advanced beginner. Players at this level have reached an intermediate thought process. player Looks for Checks, Captures and threats after opponents moves. Does not leave pieces en prise. Very good with offensive tactics and improving on the defensive tactics side, but still misses some. Still building opening repertoire. Starts learning basic endgame and middlegame strategy, but knowledge is still very basic. This level is an important milestone for the beginning chess player because they are on the verge of being an intermediate player.
1400-1500 Intermediate level player. Good thought process, does not leave pieces en prise. Advanced tactically, both on offense and defense (might occasionally miss a defensive tactic). Has an opening repertoire and plays pet openings. Has intermediate endgame, positional and analysis skills. One of the reasons for low rating is players poor positional evaluation abilities. Will probably need a chess coach to improve further.
1500-1700 Advanced intermediate player. Advanced tactical skills and thought process. Player has Intermediate endgame and positional skills at this stage. Intermediate positional evaluation and analysis skills. Should have a chess trainer, and play against strong opposition in order to improve as well as a strong focus on the endgame, positional and evaluation skills.
1700-1900 Near expert level player. Advanced tactical skills and thought process. Very strong endgame and positional skills. Intermediate evaluation skills. Very good analyst. Player needs to continue focusing on evaluation and analysis skills. Opening theory knowledge becomes an important component for further improvement. Player has a good database of structures that that can help them when they reach unfamiliar positions in OTB play. Player should reach expert level in approximately 2 more years, which falls in line with expert theory which claims that it takes 10 years to become an expert in any field.
I did not had any plan really or opening(as black after 1.d4 d5 he plays Bf4 and i was like what strange opening, maybe he wants to sac on c7...) , or tactical or endgame knowledge (besides common checkmates, forget about king and pawn endgame zero knowledge) until i reached 1400-1500. To reach 1500 you need two things. General opening principle and safe check. Check if it is safe after each move. Thats it. Havent study patterns or tactics or strategy. Just put 2 pawns at center, develop pieces and castle and try not to blunder. And with black i played ugly stuff. For example 1.e4 d5 and then exd5 and i play 2...e5! (many did not know an pasant rule!) I played my own opening moves to get out of book my opponents early to have a mess on the board so i can take all the free pieces they give me.
I analyze my games with computers and i am 1300-1400 i have to say that description is pretty accurate and i see can relate to my games in the present and in the past
Well if you are interrupted during play incessantly you DROP in score.
If you start a game and need to rush to another task ...game abandonment you drop in score. However I really think that some players CANNOT ...are not euipped brain wise to handle chess moves. You must remember this is chess requires an enhanced RIGHT BRAIN hemisphere. If you have an enlarged RIGHT BRAIN you will be a good player. Some ambidextrous players who have EQUALLY enhanced RIGHT and LEFT brain hemispheres play better. Homosexuals actually have a wider corpus collosum connecting the 2 brains and you find these people are quite clever. JUST LIKE there are MATHS dummies and LANGUAGE dummies ...the same applies to chess. Greta Chess players are not better than PRIME MINISTERS or top athletes ...they only play chess with ease
I doubt that Anish Giri has any right brain on his head
