Find the move before the clock runs out.
Other puzzle sites grade your accuracy. ClutchChess grades your accuracy under the clock.
- Clutch Rating
- A rating for how you play under pressure, not just how much chess you know.
- Targeted Drills
- Clutch Sprint, Conversion, Survival, Chaos, Bullet Panic, and Endgame Pressure. Train the spots where you lose on time.
- Puzzle of the Day
- One shared puzzle each day. Solve it before the reset to keep a streak going.
- Real Weaknesses
- Link Lichess or Chess.com to see where your clock management actually breaks down.
Why ClutchChess is different
The chess you actually play has a clock. Your training should have one too.
Most puzzle sites
- Solve at your own pace, with no clock running
- One rating that averages every kind of position together
- You play against a stored answer key
- “Correct” or “Wrong” is the whole feedback
ClutchChess
- The clock is part of the test, like in a real game
- Five pressure sub-ratings show exactly where you crack
- Play it out against a real Stockfish opponent
- Coach's Note explains the idea after every solve
About
Why this exists, and the idea behind it.
Hi, I'm Thomas, and I play a lot of chess. After enough tournaments online and over the board, I noticed a pattern in my losses: they almost always came down to the clock. I wanted to get better under time pressure, so I built ClutchChess.
Most players don't lose because they didn't know the move. They lose because they couldn't find it in time. The clock decides more blitz and bullet games than calculation does.
Regular puzzle trainers ignore that. They check whether you eventually find the answer with unlimited time, which isn't how a real game works.
ClutchChess isn't a puzzle solver with a timer bolted on. Time limits scale to the position, your rating climbs faster when you solve quickly under pressure, and the engine plays the position out against you instead of checking an answer key.
The goal isn't to make you better at puzzles. It's to make you better when it counts.

How it works
Chess puzzles where the clock is part of the test.
- STEP 1
Pick a category
Conversion, Survival, Chaos, Endgame Pressure, or Bullet Panic. Each scenario builds its own rating, so you see exactly which kind of position you crack under.
- STEP 2
Play it out, don’t just spot it
Every puzzle plays out against Stockfish at your chosen level, not a fixed answer key. You don’t need the top move; hold the advantage through the continuation and it counts as solved.
- STEP 3
Earn rating for how you got there
Fast and accurate gains you more. Solving with seconds left adds a pressure bonus. Slow but correct still counts, just for less.
What separates this from other puzzle apps
Most puzzle trainers ask one question: do you know the right move? Your rating only tracks accuracy. ClutchChess asks a second question: can you find it under the clock?
- Five pressure sub-ratings surface the specific scenario where you crack, instead of one rating that averages everything together.
- Speed and pressure modifiers actually adjust your rating. A fast accurate solve is worth more than the same move played slowly.
- Every puzzle plays interactively against Stockfish at your chosen level, not a stored line. A sloppy reply gets punished the way it would in a real game.
- You don’t need the engine’s top move. Hold the advantage through the continuation and the puzzle counts as solved. You’re training realistic decisions, not memorising lines.
- Every solved puzzle ends with a Coach's Note explaining the idea, rather than just a correct/incorrect check.
- Link your Chess.com or Lichess account and ClutchChess analyses your last two months of rated games to find where you crack under the clock, then recommends drills for it.
How the clock works
Every puzzle has a per-move clock that resets when the engine replies. How many seconds you get depends on the puzzle type and its difficulty.
- Bullet-style puzzles give you about 7 to 11 seconds per move. The whole skill is deciding fast.
- Endgame puzzles give you up to 40 to 50 seconds per move, because technique takes thought.
- Easier tiers get a bit less time, harder tiers get a bit more. The floor is 7 seconds per move and the ceiling is around 50.
Each drill runs 5 to 7 of your moves, so a puzzle takes about 35 seconds to 6 minutes.
Common questions
What's the purpose of this app?
It trains the part of chess most apps ignore: deciding under the clock. Knowing the right move isn't enough if you can't find it before your time runs out. Every puzzle has a per-move timer, and your rating climbs faster when you solve quickly under pressure, closing the gap between your puzzle rating and how you actually play.
How is this different from traditional puzzle apps?
Most apps ask one question: do you know the right move? ClutchChess asks a second: can you find it under pressure? Your speed and the time left both move your rating, the way they decide real games.
Three concrete differences:
- It's not just spot-the-move. Every puzzle plays out against Stockfish for several moves, so you have to keep the advantage through the continuation. Sloppy follow-up gets punished, like in a real game.
- You don't need the engine's perfect move. Hold the objective (convert the win, save the draw, hold the endgame) and the puzzle counts as solved. You're training realistic decisions, not memorising top engine lines.
- It splits your weakness apart. Instead of one rating, you get five, one per pressure scenario: Bullet Panic, Chaos, Conversion, Survival, and Endgame Pressure. So you can see “I'm fine in tactics but I blow winning endgames” and train exactly that.
And if you link your Chess.com or Lichess account, it reads your last two months of rated games to pinpoint where you lose under pressure, then recommends drills for it.
Who is this app for?
Any chess player. Seven tiers (Beginner through Clutch, about 400 to 2800 Elo) and your own rating set the challenge, so a beginner learning patterns and a titled player sharpening technique both get drills that fit.
It's most useful if you play rapid, blitz, or bullet and your results don't match your puzzle rating. If you've ever thought “I knew the move, I just didn't have time,” this is built for that.
