Today's Superior Sudoku in the Times (13/11/05) I could not solve, even with pencil marks, by logic alone.

I got to the point where I could not find a logical next step and I phoned a friend who had exactly the same numbers in and exactly the same pencil marks as me but she too was stuck.

In the end we resorted to trying one of the numbers in a cell with only two numbers in then working through until we got stuck. Then trying the other number worked through to a completed solution.

Is today's Superior solvable by logic alone? Are we both missing something?
