Research Methodology
Our framework for massive-scale data collection, pattern extraction, and analytical processing ensures that Chess Multiverse studies are reproducible and academically rigorous.
The Big Data Pipeline
Chess Multiverse research relies on large-scale quantitative board analytics. By processing massive historical dumps rather than isolated game samples, we establish statistically significant baselines for human performance across tens of thousands of unique positions.
Ingestion & Filtration
Our primary datasets are derived from a 20 million rated-game sample sourced from Lichess (2024). We aggressively filter this raw dump to exclude bullet time controls, provisional ratings, and engine-flagged accounts.
Proprietary Parsing
Cleaned PGNs are fed into our custom Chess Multiverse Lab v1.1 (Stable) parser. This software acts as a specialized extraction layer, identifying evaluation swings, move-time anomalies, and human blunder trends.
Pattern Extraction
The parser isolates structural phenomena. Currently, our pipeline has successfully mapped and analyzed over 15,000 distinct ECO opening variations, allowing us to evaluate opening success based on human cognitive limits rather than engine perfection.
Evaluation Standards
-
Engine Depth Minimums: Post-parsing analysis is conducted at a minimum depth of 22 ply using Stockfish NNUE architecture to ensure objective mathematical baselines.
-
Time Normalization: Unless specifically studying time-pressure fatigue, our baseline data relies heavily on Rapid and Blitz cohorts to reflect conscious human calculation.
-
Cognitive Categorization: Extracted data is strictly segmented by Elo brackets to prevent data pooling, ensuring intermediate errors are not skewed by Grandmaster accuracy.
Reproduce Our Work
We believe in open science. You can access the exact JSON databases and software frameworks we use to process our 20-million game datasets.
