Konnica

Overall strategy
Swords are not common with the Slavs. So as a result, while Slavic Light Horse may have more hitpoints, it suffers an attack penalty versus other cavalry units (especially against camels and elephants, against which the Konnica can do no damage). For this reason, the Konnica is best used for deep exploration, raiding and harassing light infantry with hit and run tactics, where its added hitpoints will serve it well. Use it to raid areas that are otherwise impassable owing to the presence of archers and towers, but remember to avoid enemy cavalry at all costs, especially ranged cavalry.

If you are facing any Slavic factions early on, Turkish cavalry, owing to their quick speed, are highly efficient as a counter-cav unit for use against Konnica hordes. Usually, three or four will suffice, owing to their powerful attack, and the Konnica's weak, pin-prick attacks.
