In this position a knight equals a queen

The best move in this position from a variation in my traxler game yesterday is QXN for white to move . Fritz shows this move delivers a -.71 where the next best move delivers the -12.

here is some fritz analysis . As Dk pointed out the king in front of the pawns in this position is a dangerous thing and something white wants to avoid.
