Researchers analyzed more than 215,000 moves from roughly 3,600 official games and found top players were more likely to pick the best move when they moved faster. That doesn’t mean you should always trust your intuition. Fast moves usually happen when a position immediately registers with a player; long deliberation happens when the position is messy or the player senses danger. The same pattern applies well beyond the chessboard.
How the study was done
To judge move quality, researcher Uwe Sunde and his co-authors used chess engines, which now outperform humans and serve as a benchmark for the best move. The researchers excluded the first 15 moves of each game because openings are often played from memory rather than active calculation. They also compared results across three time controls:
- Classical — the longest format; games can last several hours;
- Rapid — usually about 20 minutes per player for a game;
- Blitz — usually about three minutes per player.
The authors controlled for three obvious factors that could skew the results: how much time a player had left, how hard the position was to calculate, and the size of the gap between the engine’s best and second-best moves.
Across all time controls, faster decisions were associated with a greater chance a player picked the engine-recommended move. That relationship held even after adjusting for those factors. The effect was weakest in blitz, where time is shortest and every second matters.
Why a quick move can be better
The study’s point isn’t that speed alone improves judgment. Experts often decide quickly because they immediately recognize a pattern: a familiar piece configuration, pawn structure, or tactical motif. A grandmaster’s intuition is not a random hunch; it is a compressed form of experience built from thousands of games, mistakes, and corrections.
Long pauses aren’t wasted; they usually signal uncertainty, internal conflict, or hidden complexity in the position. Players stop and think when the choice is hard or when something feels suspicious.
“Here’s what sets humans apart from machines: people often instantly recognize what works and what doesn’t. But when a person can’t grasp the position quickly, they struggle to continue rational calculation,” Sunde says.
When to trust your intuition — not just in chess
Life isn’t chess, but the study offers practical lessons. There’s no universal rule to “always trust your intuition” or “always deliberate for a long time.” A more useful approach is to ask yourself three questions:
- Does your feeling come from deep experience in this area?
- Have you deliberately practiced improving this specific type of decision?
- Do you recognize patterns that match the situation you face?
If you can answer yes to most of those questions, your intuition can be a reliable guide. If you answer no, pause and analyze the options.
Good intuition often sounds like: “This crisis is exactly like one we’ve handled before.” Bad intuition often sounds like: “I just don’t like them,” “This feels hugely important,” or “Everything will sort itself out.”
The main rule is simple: don’t commit to moving fast or moving slow. Instead, identify the type of decision you face — do you recognize the patterns, or are you facing an unfamiliar problem that requires analysis?
