Algebraic chess notation(srandart chess notation):
Test#10 has uppercase letters.
To admins: please fix bug.

It seems you are right, I have AC. Many thanks!

I think Test#20 has uppercase letters, too!

The problem statement is unclear. It is not said that the letters might be capital. And the sample does not show it either. So the statement will be 99% misunderstood. That is why the authors should avoid such fuzzy expressions as "standard chess notation".

Surely, the problem statement (or the tests) should be fixed.

Now tests contain only LOWERCASE latin letters.
Problem has been rejudged, 4 authors got AC.
