 ### 2. Data Format
+After loading the dataset, we can take a first peek at a sample. But it's not very pretty yet! We will try again at the very end.
+
+```py
+example = next(iter(dataset))
+print(example)
+```
+
 A single sample from the dataset contains one complete chess game as a dictionary. The dictionary keys are as follows:
 
 1. `example['fens']` --- A list of FENs in a slightly stripped format, missing the halfmove clock and fullmove number (see [definitions on wiki](https://en.wikipedia.org/wiki/Forsyth%E2%80%93Edwards_Notation#Definition)). The starting positions have been excluded (no player made a move yet).
