To know if there's a gold in the back, you can use the scouting falcon directly on the TC and it'll see his mining camp (if not the gold itself if you use it on nearly the centre of the TC). It risks getting the khan killed though if their vills are under the TC, but this works great with berry civs who don't have their vills under the TC at the start of the game (so they can't garrison and kill your khan in the blink of an eye). That way at least you don't have to run around the whole base.
Trying to get back to the Mongol roots with more tower rushes!
