Beyond Blitz : How Fast Chess Games Impact Performance in Slow Games
Welcome back to my chess blog!
I know it's been a while since my last post, and for that, I apologize. Work has been incredibly demanding lately, leaving me little time for writing. But I'm committed to sharing my thoughts and insights with you.
Before we dive in, a quick note: I welcome all comments, questions, and constructive criticism. Your feedback helps me grow and improve, so please don't hesitate to share your thoughts.
Also, a gentle reminder: this isn't a professional blog, and I'm not vying for the "Top Bloggers" badge on (chess.com) I simply love chess and I am eager to connect with fellow enthusiasts. So, if you're looking for polished, expert-level content, you might want to look elsewhere. But if you're willing to engage with a chess enthusiast who's still learning and sharing their journey, then you're in the right place!
With that said, let's get started!

As chess enthusiasts, we've all been there - engrossed in a rapid-fire online tournament or feverishly trying to checkmate our opponent in a blistering 5-minute game. Fast chess can be exhilarating, but have you ever stopped to consider how it affects your performance in slower, more strategic games?

INTRODUCTION
‘Your knight for my pawn, and you have to take it. Things are about to get worse, sunshine. This is my game now. You have been out-calculated. I don't want the piece, I want your soul. My attack hurts like a school disco and I'm going to sac sac mate until... wait. What? 10 seconds left. But, I'm winning, right? I must be like +5 right now. Just play any move. But how do you have 10 minutes on your clock? Anyway, just play any move. That one will do, fine. For. Fuck's. Sake. Any move but that move! How could I instantly find the one move that loses? Literally, I could have played anything el...

At first, chess seems to be about the moves you play. But, after a while, you'll notice something weird. You can know more, think deeper, and play better moves, and still lose. That's because better chess is not about playing better moves. It's about playing good enough moves, quickly enough.
Playing moves faster means you play worse moves. If you have to play a game with only 3 minutes on your clock, you'll play about as well as someone 700 points lower rated than you would in a 90 minute game. Put another way, the 3 minute version of you beats the 90 minute version of you roughly 2 in 300 games(That’s what 700 point mean ) Ben Johnson and Ken Regan go in to detail Here.
It's hard to think of anything that can affect your chess strength this much. How many openings have you learned? How many strategies have you formulated? How many tactics have you solved? How many endgames have you studied? And yet, for better chess, the most valuable skill might be how you use your time.
This feels cruel. You can Improve your tactics, openings, and everything else, but if you don’t combine them in the right way, you’ll still lose. You’re like a mathematician who never learned BODMAS. You might perfectly add, subtract, multiply, and divide, but if you do it in the wrong order you get the wrong answer.
Unfortunately, after a year of maniacal chess playing, I do not have this skill. How could I? When I play chess, I just play. I have no idea what I should be doing, let alone how long I should be doing it for. And, somehow, among the endless drift of chess content, it seems few have much to say about to actually practice using the right amount of time on the right things. Only that you should.
It’s not clear what playing chess even means. Only I’m pretty sure it’s not what I’m doing: think an arbitrary amount of time until there's a move I reckon is best, or least bad, then play it. This means I run out of time, all the time. I checked Aimchess and I'm behind on the clock 90% of the time. I get sucked in to all the possibilities, especially when any move will do. The more I've learned about chess the more there is to think about and the slower I’ve got. I win the game the hard way, through calculation and planning. I then lose the game the easy way, because I'm watching the clock more than the board. Clearly, this is wrong.
How long to spend per move
The two triggers:-
A lot of what I write here is a summary or extrapolation of Dan Headman’s A guide to chess improvement. It's really phenomenal, so go buy it and read the whole thing.
You might say it's not possible to say precisely how long you should spend per chess move. Some moves are harder than others. You'd of course be right. But I suspect you're being pedantic, and we can get a practical answer and improve our game.
If you are optimizing for time alone, you should move as quickly as possible. But it is possible to spend too little time on a move. If you miss a win or blunder because you moved faster than necessary, that's a mistake. On the other hand, if you aren't optimising for time at all, you should think almost infinitely. But it is possible to spend too long on a move. If you miss a win or blunder later because you now have insufficient time, that's a mistake.
So we need one principle to stop us moving too fast, and one principle to stop us moving too slow. Dan calls these 'move triggers'. You should move when:-
Trigger 1 (if you move too fast): You have proven which move is best, so no further time is necessary. You would be willing to stand up in front of a room full of grandmasters and argue that it would not be possible to find a better move; or
Trigger 2 (if you move too slow): You have not proven which move is best, but time constraints (good time management) make it efficient for you to play the best move you have found so far. There is a time 't' which is the reasonable time to think for that move.
The first trigger is straightforward. You move as fast as possible when you're sure it's opening prep, or when you're sure of the best move. If, like my good friend @lindabell4, you're used to playing too fast, you probably move before Trigger 1. And, you might wonder 'what do I do with the rest of my time?'. We'll get to that.
The second trigger is more complicated. If, like me, you're used to playing too slow, you might wonder about the mistakes you’ll make by playing a worse move because you've hit Trigger 2. That's the trade off you make to avoid losing in time trouble. Smaller mistakes now instead of bigger mistakes later. But if reasonable time is our trigger, how long is it?
How long is it?
To answer this, we first need to understand three principles: average moves per game; Botvinnik's Rule; and critical moves. At times some of the numbers below might sound fiddly, but don't worry - you don't need to remember them. The guidelines they generate will be straightforward.
Average moves per game
There are roughly 40 moves in the average chess game (Source Here). If you use all your time in 40 moves, that's an average of ~2.5% of your time every move. If your average move time is much faster than that, you're often going to leave time - and chess skill - on the table. If your average move time is much slower than that, you're often going to run out of time. It's crude, but our first estimate for t is just 2.5% of your total time. Assuming you play some moves faster because of Trigger 1, that should give you a little buffer. But we can do better.
BOTVINNIK’S RULE
Botvinnik was a chess world champion, and his time management rule was this: In slow games, use about 20% of your time for the first 15 moves. In fast games, use less than 20% of your time for the first 15 moves (Dan has more here).
This rule is fairly intuitive. Games are not usually decided in the first 15 moves, 'the opening', and it's the most predictable and familiar part of the game so preparation and principles can speed up your play. I personally find this one tricky to stick to, though, and there are some situations where this can be ignored. For example, where you are in book for a long time or out of it very early, or where the position is highly critical move after move.
But Botvinnik knows what he’s talking about, so let’s take it as a good aim. 20% of your time divided by 15 moves is ~1.3% of your time per move. So now we have a better estimate, t is ~1.3% of your total time for the first 15 moves, and ~2.5% of your time after that. Our buffer is quite large now: by moving faster in the opening we saved time compared with if we'd just moved at our original 2.5% speed the whole time. We save ~1.1% of our time per move for 15 moves, which is ~17% of our total time. Add that to the time saved by moving faster than Trigger 1, and we've got a lot of buffer.
Now Let us analyze a game between Indian Grandmaster Praggnanandhaa vs Fabiano Caruana. Focusing more on the endgame.
Knight endings are like pawn endings. Zugzwang, king actvity and outside passed pawns are crucial. Of course, in pawn endings you do not have to think about forks and the consequences of exchanging your knight. Without the knights the position shown in the diagram would be a simple win for White. With the knights, the position is still won, but the win is more complicated. What should White do?
Some Games Played by Mikhail Botvinnik
You can find more games of Mikhail Botvinnik Here.
CRITICAL MOVES
Some moves are more important than others. Some positions have many easy to find moves which are playable. These are not critical. Some positions have one complex move which can win or lose the game. These are critical positions. Obviously we want to spend more time on moves in critical positions than non critical positions.
“Identifying critical positions is an important skill”
We have some tactical heuristics:
- When the best move may be clearly better than the second best move.
- When you have a tactical (short-lived) advantage which will disappear if not exploited now.
- When you see a move which seems to win.
And some strategic heuristics:
- When the game changes from known theory into unknown territory, from opening to middlegame, or from middlegame to endgame.
- When any pieces are exchanged, especially queens.
- When there is any change, or possible change in the pawn structure – especially in the center.
In some cases, it may be warranted to use almost all your remaining time on a critical move - for example when deciding the almost certainly final critical move in a concrete endgame position. But, most games will have several critical moves. One easy to remember suggestion here is just to double t on critical moves compared with non critical moves. If t for non critical moves is ~2.5%, on critical moves t is 5% of your total time. Given the buffer created by our faster opening play, and Trigger 1, we have time for roughly 7 or 8 critical moves per game. This seems about right based on our heuristics.
THE CONUNDRUM
With these three principles, we have a practical guide to time management. And, surprisingly, the numbers work out quite neatly. Roughly speaking, if the time control is 10 minutes, we use ~10 seconds per move for the first 15 moves, double it for ~20 seconds per move for the remaining non critical moves, and double that for ~40 seconds per move for the critical moves. If the time control is 5 minutes, it’s 5, 10, and 20 seconds per move. And so on.
Obviously these numbers are just guidelines, and should be flexed somewhat either way based on your intuition in the moment. But if you're going far longer or far shorter, you should be questioning if that's the right decision.
Here's a table for popular time controls:-

If you want to change the parameters, for example to change the time control, length of or time spent in the opening phase, average move per game, etc you can copy and edit the sheet Here.
FINDING BALANCE
I know I play too slow, but I didn’t know how to fix it. I just play, slow. Like Linda plays, fast. You’d think me playing more faster games and linda playing more slower games would be the solution. It isn’t - I’m living proof that bullet chess and time trouble are simultaneous addictions. But, I’ve found a way to practice and improve. And it starts with knowing what to think about. Poor time management is a symptom of not knowing what to think about. If you move too fast, you aren't thinking all the thoughts you need to play your best. If you move too slow, you're thinking thoughts you don't need to play your best. Practicing time management means practicing what to think about.
When I'm making a move, my thoughts often wander. I go down a chess rabbit hole and emerge in time trouble. Sometimes it's worth it, usually it's not. On the other hand, Linda doesn't wander anywhere - she plays the move she thinks is best before she's sure that it is. The answer to playing faster, for me, and the answer to playing slower, for Linda, is the same: be clear about what exactly is worth thinking about. Whether you're too fast or too slow, you need to practice your thought patterns.
If you’re used to letting your mind wander, it is brutally utilitarian. But that’s a good thing - thinking is your enemy, and now you may only think to serve the greater good. If you don’t usually think much, the extra thoughts can seem superfluous, especially if you're used to playing fast time controls. If that's the case, ask yourself, which step should you skip? The answer, I think, is none.
This thought pattern is not a prescription - it is a description of the minimum and maximum thoughts you must have to play your best chess. I suspect that's why lots of strong players recommend beginners play slow time controls: strong players can complete the necessary and sufficient thoughts very fast and mostly subconsciously. For weaker players, you can't play fast without skipping a step. Hoping you’ll develop better thought patterns by playing faster time controls is is like hoping you’ll learn Flight of the Bumblebee by playing along.
LION’S BONE’S
It can seem strange to put such a rigorous structure on our thinking in a game like chess. Are we not caging our inner chess lion? I think this is misguided. A rigorous thought pattern is not a cage, it is an x ray. It shows our lion's bones. Strong players don't notice their thought patterns - you only notice bones when they're broken. The goal is not to think, the goal is for good thought patterns to become so internalized that they form the skeleton our muscles hang on. Bones force our chess lion's muscles to work harmoniously - bones make it impossible for muscles to work any other way.
Good thought patterns allow you to figure out which muscles are weak. Do you lack quick tactical sense or calculation? Are you unable to formulate strategies or come up with candidate moves? Are you spending too long in the opening? Are you indecisive? It is impossible to answer these questions without a good thought pattern. If you calculate too long, you might mistakenly feel better in calculation than your peers. If you calculate too little, you might mistakenly feel worse. If you are playing endgames with no time on your clock, you endgames might appear bad because your openings are too slow. When your time and thoughts aren’t assembled properly, it’s impossible to build muscle in the right places.
If you complete a good thought pattern in a reasonable time and still lose, it's time to build some muscle. Until then, it’s not tactics or openings or endgames you need most. It’s time with your thoughts.
CONCLUSION
I recommend playing long 0 increment games to practice time management. Online this would be 30 + 0. There’s no way to come back after mismanaging your time with no increment. This makes them a good forcing mechanism for practicing time management.
It’s worse to run out of time than it is to play slightly ahead of time, and some games run long, so I recommend extending the move count we plan for to 45, so that we have some buffer if it looks like we’ll go to a long endgame.
Nate Solon recommends thinking in terms of time per periods or time checkpoints, rather than moves. For example, where should I be on the clock at move 15? This is useful. If we’re planning for 45 moves, the most logical periods are 15 (opening), 16-25 (middle game), 25-35 transition or mate), 35+ (endgame). So 25, 25, 35 make good time checkpoints. Including these checkpoints and planning for 45 moves makes the time table look like this:
