I can't play 10-10 or.....am I a spewtard?

[CDAC]

This is live $160 buy-in. I've played with Villian before and he is a little weak/ stationish. My image is probably LAG. I had good run early and went to showdown with KK & QQ but have been opening a lot of pots lately. My last showdown was 9-7 (flopped straight) and last hand I folded AJ after I got repopped pre. Relevant stacks:
Hero -3700
Villian -3200

50/100 Level

Villian limps UTG, folds to hero in SB with TcTd, hero raises to 400, BB folds, UTG calls, pot 900
Flop: 3s 6c 8c
Hero bets 700. Villian leans back, hands on head, thinks 15 seconds and calls. pot 2300.

Turn: 9s

Hero?

What is villian's range?
Should I raise more pf given my position?
Fold pf?
