Notes on solution, by puzzle editor:
Experienced solvers will immediately see that G=1 (leftmost digit in sum), B=9 (fifth column from right where carry is needed from fourth column so that B+1+1(from carry)=11) and A+F=10. Now think about the two columns that contain just C, E and H. Either C=5 and there is not a carry into either column, or C=4 and there is a carry into both columns. If you try C=5 and consider your choices for E and F, you'll quickly reach the answer.
