Final Wars - Update

The end-game King + General vs King + General is actually a very interesting one. I only analysed it on 8x8 boards, but I don't expect it to be much different on 9x9. (King + General can force mate on a bare King upto 14x14.) One would expect KG-KG to be a dead draw, but there actually are a large number of forced wins, which may take quite long to convert. The key seems to be whether you can keep the opponent K + G apart. Once they connect you cannot possibly win, and even K+Q would not be enough to overcome their defense. But if the K and G are separated you can just focus on cornering the K, and the G is just a helpless bystander. You don't need zugzwang to force mate with K + G, so the fact that he still has another piece can be ignored.
