Hi there tightfish

Sorry to say I don't like the way you played the hand. We can't even beat A2, let alone pocket pairs or Qx. Against a passive player, I would say we are beaten almost every time vs. the raise on the flop. I don't think anyone plays a flush draw this way - the minimum raise vs a donk bet - which is the only thing we can beat. Even against a fairly aggressive opponent, I would say our hand is no good almost always. A chop is the very best we can hope for here. I think the turn overbet is a weak pocket pair or 2x protecting. I would fold on the flop.

I would fold to the flop raise. 

In my experience, a passive opponent who limps pre is rarely going to be bluff-raising the flop. It would be a really weird way to play 34 or T6.

A value bet means that they have Qx or 2x or a small pair (I think a small pair is likely).

Against Qx and small pairs you are crushed, against 2x you are very marginal. 

It is also possible villain has a high pair and was trying to trap and is now just bombing it with KK/AA (unlikely but not impossible).

Against a flush draw like 3h4h you are not even in great shape on the flop.

I don't think villain has a bluff often enough call flop, and certainly not enough to alone check jam turn.

I would fold flop.
