Two knights in a semi open position offer you formidable swindling chances.  Objectively white should be able to stay cool in that position and increase his lead.

In my experience a rook versus knight is almost always an easy win. Even R vs. N+2P or 3P can be losing for the knight if the pawns are loose. 2R vs. 2N should be a walk in the park.

A game where 2N are actually beating 2R would be far more interesting.
