## Dataset Structure

### How to use:

```python
from datasets import load_dataset
import chess.pgn
import io


dataset = load_dataset("Icannos/chess_studies", "lichess", streaming=True)

for d in dataset['train']:
    pgn = io.StringIO(d['text'])
    game = chess.pgn.read_game(pgn)
    print(game)
    break
```

### Data Instances

Example of annotated game / study from lichess. The annotations includes arrows and circles drawn on the board in addition to natural language commentaries and sometimes

1. e4 { Do you remember the movements from the previous chapter? I hope so, because you should do them now :D } 1... e5 { That's! } 2. Nf3 { And now? } 2... Nf6 { Great job! } 3. Nxe5 { You will find this frequently in your games with this defense. That is, the most common in move 3 is that the white player takes the pawn.
How can you drive the white knight of e5? } 3... d6 { Very well! [%csl Re5][%cal Rd6e5] } 4. Nf3 { You know what you have to do now, right? } 4... Nxe4 { Excellent, you get the pawn back!
The blue arrows represent all the options the white player has to play now. [%cal Bd2d3,Bd3d4,Bb1c3,Bd1e2] } 5. Nc3 { This is the Nimzowitsch Attack!
Change the knights [%cal Re4c3,Rc3e4] } 5... Nxc3 6. dxc3 { The white player must deal with the doubled pawns on the c column
Develop your bishop [%csl Gf8] } 6... Be7 7. Be3 { What would you play now?
(Psst, your king is in the center) } 7... O-O 8. Qd2 { White wants the queenside castling
Now you must take your knight to f3, what is the shortest route? [%csl Gc1,Gf6,Gb8][%cal Ge1c1] } 8... Nd7 { That's! } 9. O-O-O { This is really the Nimzowitsch Attack.
White castles long to plan a battle of attacks on opposite flanks!
