Should You Study Openings Under 1500?

“Don’t study openings, just learn tactics and endgames” is standard advice for players under 1500, and it’s aimed at how you should spend study time — not really a claim about whether openings themselves perform differently by rating. This page checks a version of that second question that actually is measurable: for the exact same opening line, how much does the featured side’s score change between rating bands?

Score range, by opening

For each opening this site tracks, this compares its lowest-scoring rating band to its highest-scoring one (among bands with enough games to trust a percentage):

Averaged across all 10 openings with enough data to compare, the typical score range between the lowest- and highest-scoring rating band is 1.4 percentage points. That’s a real difference, but it’s a modest one next to how much game results are actually decided by tactics and endgame technique at these ratings — which this site doesn’t measure, but which every serious chess-improvement resource agrees dominates below 1500.

What this does and doesn’t show

This measures whether the SAME position scores differently by rating band — it does not measure whether studying openings improves your results faster than studying anything else, which would need a completely different kind of study (tracking individual players’ progress over time), not a snapshot of aggregate game data.
