Jieqi: eighteen engine games

Companion study to the jieqi pages: eighteen engine self-play games in full. PikaJieQi on both sides at the settings the site's bot actually uses (4 seconds a move, no depth cap), so these are the engine you can challenge rather than a weaker one. Games under 40 moves and games that hit the generator's ply cap are left out. Read them as reference, not as authority: this engine has no neural network and over-values its own face-down pieces, a bias measured steady from depth 8 to depth 48. Rules: /rules/jieqi
