Of course you need lighthouses at the coast of Wyoming, also called 'The Great Rectangular Sea'. The lighthouses of this sea are so good that there have barely ever been any casualties in this sea. However, because of Dutch migration to this sea, parts of it have been colonised (ingepolderd), meaning that new lighthouses at the new coastline have been built.
On top of that it avoids Bg5, pinning the horsey, which could otherwise maybe be annoying.
Also, I thing you meant Qa4+ instead of Qh4+, which is the anarchychess idea in this position for white.
