This reg has been giving me a lot of trouble when I play 200nl. Mainly by pure aggression- raising flops and/or turns and continuing with big sizing. For the most part I haven't been able to continue, but about 5 min before this hand came up he raised my turn bet on a very drawy board, and I b-jammed the 2nd nut str8 and he folded.
I open KJhh utg because both the blinds are the fish (the reason I'm playing). villain CC's from btn everyone else folds.

flop: Ks 5d 3d
I cbt 2/3 pot-ish and he Rs about 3x- I call.

Turn 7c
I check and he bets about 2/3 pot like he's been doing. Is this a bad spot to x-jam? I feel like he has tons of draws and few sets. I dont imagine he would raise KQ for value here so that leaves him quite polarized. So KJ picks up a lot more equity on this turn card. Added to the fact that I need to pick spots to 'play back' to not let him run over me I feel this could be the perfect type of spot.

Thoughts?
