### Model Details
|
6 |
+
|
7 |
+
- **Model Name**: Advanced Magnus Carlsen Chess Model
|
8 |
+
- **Model Version**: v20250626_170216
|
9 |
+
- **Model Type**: Neural Network for Chess Move Prediction
|
10 |
+
- **Architecture**: Transformer-based AdvancedMagnusModel
|
11 |
+
- **Parameters**: 2,651,538
|
12 |
+
- **Framework**: PyTorch
|
13 |
+
|
14 |
+
### Intended Use
|
15 |
+
|
16 |
+
This model is designed to predict chess moves in the style of Magnus Carlsen, the world chess champion. It can be used for:
|
17 |
+
|
18 |
+
- Chess analysis and training
|
19 |
+
- Move recommendation systems
|
20 |
+
- Chess AI applications
|
21 |
+
- Educational chess tools
|
22 |
+
- Research in chess AI
|
23 |
+
|
24 |
+
### Training Data
|
25 |
+
|
26 |
+
- **Source**: Magnus Carlsen's professional games
|
27 |
+
- **Size**: 500+ games processed
|
28 |
+
- **Preprocessing**: Advanced position feature extraction
|
29 |
+
- **Vocabulary**: 945 unique chess moves
|
30 |
+
|
31 |
+
### Performance
|
32 |
+
|
33 |
+
- **Test Accuracy**: 6.65%
|
34 |
+
- **Top-3 Accuracy**: 11.58%
|
35 |
+
- **Top-5 Accuracy**: 14.17%
|
36 |
+
- **Training Time**: 140+ minutes
|
37 |
+
|
38 |
+
### Limitations
|
39 |
+
|
40 |
+
- Trained specifically on Magnus Carlsen's playing style
|
41 |
+
- May not generalize to all chess positions equally
|
42 |
+
- Requires proper position feature extraction
|
43 |
+
- Performance varies by game phase and position complexity
|
44 |
+
|
45 |
+
### Ethical Considerations
|
46 |
+
|
47 |
+
- This model should be used as an educational and analysis tool
|
48 |
+
- Not intended to replace human judgment in professional chess
|
49 |
+
- Users should understand this represents one player's style, not objective "best" moves

# How to Use the Advanced Magnus Chess Model from Hugging Face
|
2 |
+
|
3 |
+
## Quick Start Guide
|
4 |
+
|
5 |
+
Once your model is uploaded to Hugging Face, here's how others can use it:
|
6 |
+
|
7 |
+
### 1. Installation
|
8 |
+
|
9 |
+
```bash
|
10 |
+
pip install huggingface_hub torch chess numpy pyyaml scikit-learn
|
11 |
+
```
|
12 |
+
|
13 |
+
### 2. Download and Use the Model
|
14 |
+
|
15 |
+
```python
|
16 |
+
from huggingface_hub import hf_hub_download
|
17 |
+
import chess
|
18 |
+
import sys
|
19 |
+
import os
|
20 |
+
|
21 |
+
# Download model files (replace YOUR_USERNAME with your actual username)
|
22 |
+
repo_id = "YOUR_USERNAME/advanced-magnus-chess-model"
|
23 |
+
|
24 |
+
# Download required files
|
25 |
+
model_path = hf_hub_download(repo_id=repo_id, filename="model.pth")
|
26 |
+
predictor_path = hf_hub_download(repo_id=repo_id, filename="advanced_magnus_predictor.py")
|
27 |
+
config_path = hf_hub_download(repo_id=repo_id, filename="config.yaml")
|
28 |
+
|
29 |
+
# Add the download directory to Python path
|
30 |
+
download_dir = os.path.dirname(model_path)
|
31 |
+
sys.path.append(download_dir)
|
32 |
+
|
33 |
+
# Import and use the predictor
|
34 |
+
from advanced_magnus_predictor import AdvancedMagnusPredictor
|
35 |
+
|
36 |
+
# Initialize the predictor
|
37 |
+
predictor = AdvancedMagnusPredictor()
|
38 |
+
|
39 |
+
# Analyze a chess position
|
40 |
+
board = chess.Board("rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq e3 0 1")
|
41 |
+
predictions = predictor.predict_moves(board, top_k=5)
|
42 |
+
|
43 |
+
print("Magnus-style move predictions:")
|
44 |
+
for i, pred in enumerate(predictions, 1):
|
45 |
+
move = pred['move']
|
46 |
+
confidence = pred['confidence']
|
47 |
+
san = board.san(chess.Move.from_uci(move))
|
48 |
+
print(f"{i}. {san} ({move}) - {confidence:.3f} confidence")
|
49 |
+
```
|

+
## Advanced Usage
|
63 |
+
|
64 |
+
### Batch Analysis
|
65 |
+
|
66 |
+
```python
|
67 |
+
positions = [
|
68 |
+
"rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq e3 0 1",
|
69 |
+
"rnbqkbnr/pp1ppppp/8/2p5/4P3/8/PPPP1PPP/RNBQKBNR w KQkq c6 0 2",
|
70 |
+
"rnbqkbnr/ppp1pppp/8/3p4/2PP4/8/PP2PPPP/RNBQKBNR b KQkq c3 0 2"
|
71 |
+
]
|
72 |
+
|
73 |
+
for i, fen in enumerate(positions):
|
74 |
+
print(f"\nPosition {i+1}: {fen}")
|
75 |
+
board = chess.Board(fen)
|
76 |
+
predictions = predictor.predict_moves(board, top_k=3)
|
77 |
+
|
78 |
+
for pred in predictions:
|
79 |
+
san = board.san(chess.Move.from_uci(pred['move']))
|
80 |
+
print(f" {san}: {pred['confidence']:.3f}")
|
81 |
+
```
|
82 |
+
|
83 |
+
### Integration with Chess Engines
|
84 |
+
|
85 |
+
```python
|
86 |
+
import chess.engine
|
87 |
+
|
88 |
+
# Combine Magnus predictions with Stockfish analysis
|
89 |
+
stockfish = chess.engine.SimpleEngine.popen_uci("/path/to/stockfish")
|
90 |
+
|
91 |
+
board = chess.Board("your_position_fen")
|
92 |
+
|
93 |
+
# Get Magnus-style predictions
|
94 |
+
magnus_predictions = predictor.predict_moves(board, top_k=5)
|
95 |
+
|
96 |
+
# Get engine analysis
|
97 |
+
engine_result = stockfish.play(board, chess.engine.Limit(time=1.0))
|
98 |
+
engine_move = engine_result.move.uci()
|
99 |
+
|
100 |
+
print("Magnus predictions vs Engine:")
|
101 |
+
for pred in magnus_predictions:
|
102 |
+
move = pred['move']
|
103 |
+
san = board.san(chess.Move.from_uci(move))
|
104 |
+
marker = " ⭐" if move == engine_move else ""
|
105 |
+
print(f" {san}: {pred['confidence']:.3f}{marker}")
|
106 |
+
|
107 |
+
stockfish.quit()
|
108 |
+
```
|
109 |
+
|
110 |
+
