In C# you can't declare a new variable in an if statement. What are you trying to test with that if statement?

Don't use var - use the actual variable type. It's not what's causing the problem in this case, it's that your caps KEY IS STUCK DOWN and you have spurious semicolons!

Try this:

C#

public static void Main(string[] args)
    {
    int chess = 8;
    string dark = "x";
    string light = "y";
    for (var line1 = 0; line1 < chess; line1++)
        {
        for (var column2 = 0; column2 < chess; column2++)
            {
            string result;
            if (line1 == 0)
                {
                ...
                }
            }
        }
    }

Semicolon is a statement terminator in C#, so when you put one at the end of your for loops:

C#

for (var line1 = 0; line1 < chess; line1++) ;
{
 for (var coloumn2 = 0; coloumn2 < chess; coloumn2++) ;

It ends the scope of the variable you declare within it.
