I disagree strongly.

The board is extremly drawy. I can easily see Button play a draw like he has played in this hand.

In fact, he "must" be on either a draw (or possibly a dumb A-high). Really the way he has played it, 3-betting the flop for a free card. With all that cooordination on the board. It screams draw.

Since he 3-bet before the flop he is likly to have high draws: AK, AQ, KQ. But he will also have a bunch of other cards alot of the time. At least that is my experience.

On the river he won't fold A-high. Maybe not KQ either.

Hero needs to check-call to induce bluffs from all the crazy hands villain would play sometimes.

If he had 89 he should bet, hoping that KQ all the crazy hands villain will play sometimes fold.

That is what I think at least.
