Per the recent discussion here about Color Wraps...

The "One-Trick Pony" for 9 Aug 2007 at Sudocue.net provides an example. There are numerous simple reductions (locked sets, Box-Line) until there are 27 unsolved cells remaining. At that point, there are only three digits that provide coloring possibilities. One of them immediately produces the Color Wrap and solves the puzzle. (Reminder: A "Color Wrap" occurs when two instances of the same color/polarity fall within a single house. All instances of that color are then eliminated.)
