don't build hashishins. they are waste of florins IMHO.

use lots of HAs and tons of hybrid troops. use ottoman inf for armor piercing.

avoid their longbows like a plague since they outrange anything you have. BTW, u don't get crossbows or arbs.

don't easily take on longbows as their melee can also give you a nasty surprise.

AHC and valour is better. always choose valour over armor as it boost defense but also is not vulnerable to AP weapons.

just use common sense. play like historical turks and hit and run until they drop dead. try and separate their heavily armoured troops and pick them off individually. pull them away from longbow's protective fire and your HA's can waste them. use the knight's impetousity against them.
