hero?

villain again unknown, but i suppose there are a lot of Tx in his CO range( this is a general assumption, based on fact that he is a russian and generally they are damn wide in LP), like ATs,KTs,QTs,JTs,9Ts besides PP. i bet flop to get value from 33-99,JJ.
turn i am thinking b/f or c/c, but i dont know wich.... if i get called, or i c/c, river what do i do? may seems an easy/silly situation for most of you, but this is a tough spot for me and dont know wich decision is best.
