JJ IP versus 3Bet

Great OverThink strikes again here

Villain is VP 24/PF 22/3Bet 4/Agg 5 over 146 hands.

Had previously seen him play QQ aggressively on a flushy board and get outdrawn.

Party Poker No-Limit Hold'em, $0.04 BB (5 handed) - Party-Poker Converter Tool from FlopTurnRiver.com

Hero (UTG) ($4.87)
Button ($5.48)
SB ($2.14)
MP ($4.18)
BB ($6.91)

Preflop: Hero is UTG with J, J
Hero bets $0.16, MP calls $0.16, 2 folds, BB raises $0.80, Hero calls $0.68, 1 fold

Flop: ($1.86) 6, 3, 5 (2 players)
BB bets $1.32, Hero???

If he's 3Betting the full 4%, preflop is a coin-flip. Flop doesn't help him/her, so i've now got an 11:9 edge; the cBet is inevitable....

Should i credit an unknown 4NL TAG with adjusting to an EP raise?
