Don't auto-resolve and bring some cavalry? There is a bug in the game that prevents some two-handers from attacking cavalry. Last night, I charged a unit of tabardariyya into the flank of a unit of mongol light lancers and had my axemen wiped out without causing a single casualty. They may be powerful in auto-resolve, but they are useless on the actual battlescreen.

Without taking advantage of a bug, I guess you could deal with them as any other powerful two-handed melee unit: use missiles. They don't have shields and aren't really going to be catching up with turkomans or the like.
