Full ring live 1-2/5 PLO  Villain is most aggro player at table every button straddle where he is in SB he blind pots it to 40$. 

Villain stats are something like 40/30/8 and views me as most dangerous player at table and muttered it to himself as I sat beside him. 

EFF stacks $1600 

Button straddle($10) KcQdTc7d  I bet 40$ from UTG villain UTG+1 then 3B to $80 everyone folds I flat, HU to flop pot $180

Flop is JcTd4c   I decide to donk $155  for some info as villain tends to overplay some hands but  my read is he isn't gonna get it in super light vs me and may be more cautious and narrow his GII range vs me. He flats my $155 and the turn is 6 of spades a blank. We have $1365 behind and pot is 490 I decide to go with a check jam to a smaller turn bet but he then full pots it?  I feel he's bombing away on the flop with NFD+combo of gutters and over pairs and am confident the king high FD is best but with no FE I don't think I should jam but folding would be terrible IMO.  Can anyone tell me where I went wrong in this hand and if there's a better line to take?
