min 3-bet QJs, flop two pair, line?

[daven]

Villain is 24-16 with high flop aggression.
3-betting QJs here is only occasionally. 3-bet sizing is something i toy with, the two standards for me here would be to $2.50 (as played, rare) and to $4/$4.50 (normal).
Villain's range to call this 3-bet is likely narrow. I expect a 4-bet from pairs QQ+, a call from AK/AQ/AJ/KQ (I don't expect AT, but I guess it could show up) and pocket pairs.
I'm ahead of most of this range, and the turn bet screams fear (some pair/ace kicker).
Pretty sure villain is folding to a raise here (expecting i have TPTK+), should I flat call again and try and extract a river bet?

MP1 bets $1.5, Hero calls $1.50.

MP1 bets $2.5, and me: flat call and max out on the river, or raise here? how much?

Weirdly played hand... I'd raise the flop donk-bet. You showed strength PF, now follow through. Your hand isn't strong enough to slow-play IMO - a T, A or a club are all bad cards for us. What is your reasoning for occasionally min-3-betting pre with a hand like QJs? Do you do this with AA/KK also? If I were villian I'd be calling with anything I opened with - how can you fold with such great pot odds?

Why did you 3-bet so weakly? Seems to me that if you 3-bet strong with strong hands, you shouldn't be telegraphing your weakness by weak 3-betting a fairly marginal hand.
