Some teachers seem to think the hardest thing about the opening is how to pronounce the  name of the Dutch town where it was introduced (SKE-VEN-ING-EN) and offer it up to intermediate students. But they ignore the fact that its strategic subtlety is what appeals to top players. Making decisions in the middlegame is fiendishly difficult! Nevertheless it remains one of the most popular chess openings.
