Villain plays 30/24/11 after 187 Hands, RFI BU 58%, F23Bet 33%, F2Cbet 33% but 0 in 3Bet Pots (3 Hands)

I guess preflop and flop are pretty standard. He most likely calls with his pairs and a lot of random floats based on his stats and that he's been quite aggressive. OTT I decide to barrel again against 99-66 and turned FD, to capitalize on dead money and fold out his floats/equity share. After his call his range gets pretty strong but OTR I decide to check call because I thought he is the type of guy who could turn some of his SD value into a bluff using the scare card. The A doesnt really hit his range imo except turned Ax in clubs. And there arent a lot of 7x in his BU Range vs. a 3bet from SB, right?

Makes sense? Too loose?
