Stunning resource in the critical match between Austria and Poland

In round 6 of the 45th chess olympiad in Budapest the underdog from Austria at board one (Black) seemed to be in a hopeless position against the Polish no.1, GM Duda. 3 pieces are hanging at the same time and the king is far from safe.
But Dragnev found a way to draw this game! Can you spot it too?
