♟️ GambitFlow: Elite Opening Theory (2000+ Elo)
📊 Dataset Overview
This dataset serves as the "Opening Memory" for the GambitFlow AI project (Synapse-Edge). It contains millions of chess positions extracted exclusively from Elite Level Games (Elo 2000+) played on Lichess.
The goal is to provide the AI with Grandmaster-level intuition during the opening phase, preventing early positional disadvantages.
