Heh.. I was fighting a slightly inferior enemy, both armies placed on the low flatgrounds with a hill in between them on the enemies half. Well, since the hill was such an obvious defensible point, at first I was a little disappointed that he wasn't immediately heading towards it thanks to you people who've hyped the AI so much for me (and, to be honest, I had already seen the AI seek out better standpoints already). Anyway, as I marched up towards him, the AI suddenly yanked to life and sent all the men running for the hill, however, at this point I was already too his men. The only unit of it's who made it up the hill was the Light Cavalry "general". The rest, two units of spearmen, was engaged by to Yari units of my own, while my third Yari spearwalled itself on the slope to further cut off the cavalry and my general circled around the mess to deal with the enemy archers. The Light Cavalry then (well, not directly, I suppose, rahter when the archers were routed and the the other units began to loose) foolishly charged my spearwall in what I guess was an attempt to break through and attack my other Yari in the rear, getting him slaughtered. Not the brightest moment of the AI, I guess, but damn it feels good to have an enemy that actually does something on the battle field!
I've also been tricked twice by the AI's "cunning" flanking techniques. Really goes to show I'm not used to defending against anything else than a head on charge.
