Very well done David!

You code is really good!

Readability formatting is all personal preference. I find yours to be a little confusing, although a lot more readable than other predicates I've read today. In the future, your code will depend on whatever your team or company deems worthy. Until then, find a formatting that your are confortable with others reading; something that makes you look good.
Your code:

check_alive(Row, Column, Board, Colour, Visited):-

    %...

    (Stone = e;

        (Stone = Colour,

            \+ is_visited((Row, Column), Visited),
            Left is Column - 1,
            Right is Column + 1,
            Up is Row - 1,
            Down is Row + 1,
    (
        check_alive(Row, Left, Board, Colour, [(Row, Column) | Visited]);
        check_alive(Row, Right, Board, Colour, [(Row, Column) | Visited]);
        check_alive(Up, Column, Board, Colour, [(Row, Column) | Visited]);
        check_alive(Down, Column, Board, Colour, [(Row, Column) | Visited])
    )
)).

Airy formatting:

check_alive(Row, Column, Board, Colour, Visited):-

    %...

    (
        Stone = e;
        (
            Stone = Colour,

            \+ is_visited((Row, Column), Visited),

            Left is Column - 1,
            Right is Column + 1,
            Up is Row - 1,
            Down is Row + 1,

            (
                check_alive(Row, Left, Board, Colour, [(Row, Column) | Visited]);
                check_alive(Row, Right, Board, Colour, [(Row, Column) | Visited]);
                check_alive(Up, Column, Board, Colour, [(Row, Column) | Visited]);
                check_alive(Down, Column, Board, Colour, [(Row, Column) | Visited])
            )
        )
    ).

Thanks for your hard work!

The issue contains feedback on the formatting of the Prolog predicate check_alive/5, but it does not identify a file, test, or required change. Review the referenced code and repository context first; there is no explicit completion criterion beyond the general formatting comments.
