This is a simplified problem from a game I just played. I won the race and the game from here, but in post game analysis this position has a lot of different possibilities. Lots of clever moves and counter moves. Almost every move that white might think to make leads to interesting possibilities. I'm honestly not sure of what the optimal play would be here.

This is the game it's from, for the curious.
