How to go from 800 to 1200 in chess: what changed in my 1,234 games
To go from 800 to 1200 in chess, the first thing to fix is losing pieces in the opening, then learning to take the pieces your opponent leaves loose, and then finishing the games you win. That's what changed in my own climb on Chess.com: 1,234 rapid games from January 10 to December 24, 2024. My overall accuracy barely moved (76% to 78%), but the share of games where I blundered in the first ten moves fell from 48% to 30%.
This guide splits that climb into its four 100-point stages, with the engine numbers for each one, two positions that show how the same mistake changed shape, and a plan you can follow. Every number comes from the Stockfish analysis of my games (account nacsol3, rapid only). Your path will be different, but you can measure the same things.
If you've already reached 1200 and stopped there, the plateau has a different cause, and I wrote a separate guide on being stuck at 1200.
How long does it take to reach 1200 in chess?
There is no deadline I can give you from one player's history. In this rapid series, the first crossing of 1200 was on December 24, 2024, after game #1,237. The 800-to-1200 segment above starts at game #3, on January 10: 1,234 games between those milestones. That is an observation about my account, not an average for beginners or a prediction for you.
Keep three questions separate when you compare your own progress:
| Question | What to record |
|---|---|
| How much calendar time passed? | Dates of the first game and the first crossing, including breaks |
| How much did I play? | Games in the same time-control pool, rather than all formats combined |
| Did the improvement last? | Results after the crossing, rather than the highest number on one day |
A first crossing is a milestone, not a permanent floor. My December week 51 diary documents the first crossing; week 52 documents what happened next. These are examples of one player's path. If you want a timetable for yourself, start by reviewing a small set of your own finished rapid games and naming one recurring mistake. Measure whether that mistake becomes less frequent before deciding that your schedule is failing. A rating target alone cannot tell you which move to change.
My path from 800 to 1200, in four stages
| Stage | Reached at game | Games needed | Dates | My accuracy | Games with a blunder in the first 10 moves | Opening blunders per game |
|---|---|---|---|---|---|---|
| 800 → 900 | #32 | 29 | Jan 10 – Jan 15, 2024 | 76.0% | 48% | 0.90 |
| 900 → 1000 | #232 | 200 | Jan 15 – Feb 28, 2024 | 77.3% | 37% | 0.64 |
| 1000 → 1100 | #656 | 424 | Feb 28 – Jul 4, 2024 | 77.3% | 31% | 0.57 |
| 1100 → 1200 | #1,237 | 581 | Jul 4 – Dec 24, 2024 | 77.9% | 30% | 0.56 |
Three things stand out:
- Each stage took longer. 29 games, then 200, then 424, then 581. Early on, a few good games move a new account a lot. My first rating was 631 and I was already at 800 by game 3 (the story of that start). After that, every 100 points cost more games. If going from 1000 to 1100 feels much slower than going from 800 to 900, that's normal.
- Accuracy is a poor progress bar. It rose less than two points over the whole climb. My opponents got better at the same pace, so the percentage stays flat while the rating goes up.
- The opening is where I clearly improved. Almost every other number stayed in the same range. I made about 2 blunders per game at every stage (1.93 at the start, 2.18 at the end), and so did my opponents.
"Blunder" here means a move that drops at least 15 points of winning chance according to Stockfish. If those labels are new to you, this page explains inaccuracy vs mistake vs blunder.
Common advice for this exact jump is similar. In a Chess.com thread about going from 883 to 1200, replies list learning opening principles, converting basic winning endgames, practicing basic tactical patterns and thinking before each move, and one reply sums it up as not blundering pieces and taking the ones your opponent blunders (Chess.com forum, January 27 – February 2, 2023). My data agrees on the order: first stop giving pieces away, then take theirs.
Stage 1: 800 to 900. Stop losing your queen in the opening
At 800, almost half my games had a blunder by move 10. Many of them were the same type: my queen came out early and went to a square where something cheap could take it.
January 27, 2024, game #106. I'm Black against ViktarSplinfao (888), rated 873, 20-minute game (game on Chess.com). White has brought the queen to h5 and the bishop to c4, both aiming at my f7 pawn, and has just played d3.
What I played (red arrow): queen to f5 (Qf5). It attacks White's queen and the pawn on f2 at the same time, a double attack, which is a move that threatens two things at once.
What I missed: the pawn on e4 can simply take my queen. That's what happened, and I resigned on move 5.
The better move (green arrow): queen takes the pawn on f2 with check (Qxf2+). My bishop on c5 protects the queen there, so the king can't take it and has to walk to d1. Stockfish rates it −6.18, winning for Black.
The lesson: before you move a piece, look at every enemy piece that could take it on its new square, including pawns. Pawns are the attackers beginners forget most, because they capture sideways but move straight.
The rest of this stage was a roller coaster: I reached 900 in game 32, then lost nine in a row and was back at 860 by mid-February. I wrote about that week in my diary: stuck in the 800s after nine straight losses. The 900 milestone post covers how fast that first jump was.
Stage 2: 900 to 1000. Fewer free pieces, same opening
This stage took 200 games. The share of games with an early blunder fell from 48% to 37%, and opening blunders from 0.90 to 0.64 per game. I didn't learn a new opening to do it: my most played line was the same Queen's Pawn setup throughout. What changed was a habit: before each move, asking whether the piece I'm moving can be taken.
Two things didn't improve yet. I still walked past my opponents' gifts about 1.3 times per game, and when I got a winning position I won only about two thirds of them. Those became the next two stages. The full story of the last games before 1000 is in reaching 1000.
Stage 3: 1000 to 1100. Take what they give you
This was my first real plateau: 424 games, with my rating stuck between about 950 and 1050 for months. At 1000 both I and my opponents blundered about 2.2 times per game, so the results depended on who took advantage. I wrote a whole guide on it: stuck at 1000 Elo, with three positions and the three "leaks" I measured.
The short version: my opening blunders kept falling slowly (0.57 per game), but my rating only moved once I started asking, after every opponent move, what did that move leave undefended?
Stage 4: 1100 to 1200. The same question, later in the game
The last stage took 581 games, all of them 10-minute games. By now my early blunders were down to 30% of games, but the old mistake didn't disappear. It moved into the middlegame and started to look less obvious.
December 15, 2024, game #1,186. I'm White against Tepelke (1107), rated 1120, 10-minute game (game on Chess.com). Black's knight has just jumped to d5, right in front of my rook on d1, and nothing defends it. Stockfish gives me +6.17.
What I played (red arrow): knight to d4 (Nd4), aiming at the e6 square (it went there next move). I had almost nine minutes left.
What I missed: two things at once. The knight on d5 was free: my rook takes it (Rxd5) and Stockfish rates that +6.42. And my own knight on d4 can be taken by Black's e5 pawn. After my move the evaluation went to −2.76. My opponent didn't see it either, and I won the game later, which is exactly why a mistake like this survives: the result hides it.
The lesson: the question from 800 still applies at 1100, in both directions. Can my piece be taken where it lands? and is any of their pieces already free? At 800 I missed these in the first ten moves. At 1100 I missed them on move 13 or move 30.
A plan to go from 800 to 1200
- Pick one simple opening for White and one answer each to 1.e4 and 1.d4. Play them every game. The goal is to reach move 10 without losing material, not to learn theory.
- Ask two questions before every move. Can the piece I'm moving be taken there? What did my opponent's last move leave undefended? Example 1 fails the first question; example 2 fails both.
- Review every game for 10 minutes. Look for the first big swing in the evaluation graph and what you could have done instead. Here's a step-by-step routine for beginners.
- Track one number per stage. At 800, count games with a blunder before move 10. At 1000, count opponent mistakes you didn't punish. Near 1200, count winning positions you didn't win.
- Turn your own misses into puzzles. Retry the positions from your games until you find the move without help (puzzles from your own games).
- Expect each 100 points to take longer. In my case, about 30 games, then 200, then 400, then 600. Plan for months, not weeks.
Common mistakes on the way from 800 to 1200
- Judging progress by accuracy. Mine went from 76% to 78% while my rating went up 400 points.
- Changing openings after every loss. At 800 the games are lost to loose pieces, not to theory.
- Bringing the queen out to chase pawns. Example 1 was a queen adventure on move 4.
- Playing on tilt. Nine losses in a row in the 800s felt like a collapse. Less than three weeks later I reached 1000.
- Assuming a win means you played well. My game #1,186 was a win with a +6 to −3 swing in it. Review your wins too.

Frequently asked questions
How long does it take to go from 800 to 1200 in chess?
It varies a lot between players. For me it took 1,234 rapid games on Chess.com, from January 10 to December 24, 2024. Each 100 points took longer than the one before: 29 games, then 200, then 424, then 581.
What is the most important thing to fix between 800 and 1200?
In my games, blunders in the opening. The share of my games with a blunder in the first 10 moves fell from 48% at 800 to 30% at 1100. My overall accuracy barely moved, from 76% to 78%.
Do I need to learn openings to reach 1200?
You need a simple opening you play the same way every time, not a lot of theory. My most common opening barely changed from 800 to 1200; what changed was that I stopped losing pieces in the first ten moves.
Is it normal to go back down after reaching 900 or 1000?
Yes. I reached 900 in game 32 and, less than a month later, was back at 860 after nine losses in a row. Look at your rating over a month, not a week.
Should I play faster or slower games to get from 800 to 1200?
Forum advice usually says slower games. I played mostly 20-minute games up to 1000 and only 10-minute games from 1100 to 1200, and the climb kept going. Few of my blunders came in time trouble at any stage.
