Arne recently played in a chess tournament, and one of his opponents played the unusual 1.f4, which was quite a surprise. Sadly, he didn't film this Smart Moves episode before the tournament, to get to know the surprising answer Nh6!? The so called - Horsefly Defence in the Bird Opening. Even the engines think that this counter is absolutely legit, and the Mega Database shows excellent results as well. Svitlana shows, why it is a powerful move!
