3/6: DEEP, I'm scared, luckily my hand keeps improving

[ValarMorghulis]

Villain is lanausee on PartyPoker.

He seems to be running about 21/24 over 100 hands with an ATS of 43.

We've clashed a bit: One hand, he called my 3bet and flop cbet, he folded on the river. Another hand, he raised my cbet, I 3bet and he folded.

How have I done so far and what's my river play?
