  I don't think so. First, the strong player needs to know about this weakness.
This would imply knowing the source code (very improbable) or studying thousands
of games and _guessing_ that there's that weakness.
  And after that, the strong player has to be lucky to reach a position where
this weakness can show up. Maybe a probability of 1/1000. And then, he has to
calculate very well to avoid the knight to scape.
  Quite improbable...
