    Draw a bar chart of the counts of each unique value in the 'value' column of a pandas DataFrame and return the Axes object.
    Empty DataFrame will return an empty bar chart.
    
    Parameters:
    df (DataFrame): The pandas DataFrame with columns ['id', 'value'].

    Returns:
    Axes: The matplotlib Axes object of the bar chart.

    Raises:
    - The function will raise a ValueError is input df is not a DataFrame.

    Note:
    - This function use "Value Distribution" for the plot title.
    - This function use "Value" and "Count" as the xlabel and ylabel respectively.

    Requirements:
    - pandas
    - matplotlib.pyplot

    Example:
    >>> df = pd.DataFrame({'id': [1, 1, 2, 2, 3, 3],'value': ['A', 'B', 'A', 'B', 'A', 'B']})

Draw a bar chart of the counts of each unique value in the 'value' column of a pandas DataFrame and return the Axes object. Empty DataFrame will return an empty bar chart.
Note that: This function use "Value Distribution" for the plot title. This function use "Value" and "Count" as the xlabel and ylabel respectively.
The function should raise the exception for: The function will raise a ValueError is input df is not a DataFrame.
The function should output with:
    Axes: The matplotlib Axes object of the bar chart.
You should write self-contained code starting with:
