Two pair facing agression

What hands will call a shove on flop?

QJ, KJ(less possible), AT or JJ.
KK and QQ i think he 3bet me pre.
I only call because i thought he probably can AT in his range, when the A falls OTT i just fold.
What's the better play?

I would either shove OTF or fold it right away, calling the flop achieves nothing - it is very unlikely that you will improve OTT and very likely that you will face another big bet from Villain + you are OOP. Some people will play their big draws very aggressively so you could be even against an A2s kind of hand against which your hand won't perform that great either. From the stats you provided, Villain doesn't seem to be very aggro, so I would be a bit scared here when he is raising you.

Also, from my experience playing NL2, when someone is raising big (and Villain here is), they have a monster, so I would be afraid you are behind a lot of the time. That said, we are still talking about NL2 and people will play all kinds of crazy stuff, so shove OTF is not that bad.

I'm not sure we achieve much by calling OTF. He will have better made hands, weaker made hands and some draws that could call your shove, but I guess you might be just flipping against his range? Imo you could get it in or just fold.

How about "keeping bluffs in his range"?

But I really don't know what is right here.

With a shove he will not fold much hands or he will fold those that we beat anyway. The ones that he calls will have enough equity.
