If you want to exploit the ai go for towers or pick poles and go for defensive towers into knights.
If you want to win fair and square then aside from executing a build well, strategizing well or having good micro, try raiding in castle age, the ai isn’t great at defending vills so you can quickly get a vill lead.
Turks are good in the late game, you just need more production buildings in imperial age(10 or 12, not 4 or 5) and to mass units earlier (cav archers, light cav and janis are available in castle age, make some for imp).
Ending the game early is preferable for Turks so don’t be too passive and inevitably run out of gold.
If you need more time to create your army then you can turtle with the longest range bombard cannons in the game and with castles or bombard towers to kill anything trying to touch your bombard cannons.
