Pre: Standard.

Flop: I see no reason to slow play here, when we get raised here I would expect to be able to play for stacks very often so I would just be three betting getting it in here. KK is almost impossible so we essentially have the nuts and have a huge range advantage.

Turn: 44 is still possible here, as is KJ type hands. I'm for sure not shocked to see QT here but we still have equity against this hand, I'm not folding here.

Agree as above, just get this in on the flop, board is very wet and we can stack draws and two pairs now before the board kills our hand.

The flop is an easy reraise with KJ QT and flush draws possibly playing this way.

As played the turn is a puke spot against a passive looking player. It's not many hands but a clear pattern can be seen. Many will disagree but hero folding here can't be bad. I think it's a bit of a cop out to say well he can have KJ or 44, because we can't expect him to play those hands this way all of the time.
