# ♟️ 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. |
