Hero is playing tight aggressive picking up some small pots in position and not getting to showdown much.
Villian is a slightly aggro euro has made some loose preflop raises like AK92 suited to the ace in the SB over 5 limpers. Capable of bluffing and plays a wide calling range.

What range should villain expect me to show up with? Make the hero call here? Flop and turn line ok? I wasn't happy bet getting this in on the flop or bet folding.
