How to counter Turks Post Imp?

Hi, as the title says, I want to know how counter the comp of janissarys and BBC. I played a FFA Game as magyars and went for Huszars + CA and I just couldnt handle this at all. He played a slow push setting up castles and then just razed my buildings with the bbc. when I engaged the jannis killed my huszars and If it was close he just went back to the castle. my trebuchets would get sniped aswell as my onagers. Is there any effective way to stop this? He had plenty of gold, so I couldnt just win the gold battle...looked it up in the postgame lobby...he had gathered like 45k gold, while I was at 25k
