No reads about Button.

What should I do?

[Tregan]

Edited out because I completely misread the hand.

[Bosox]

call, he's got a set.

Why he first should slowplay his set on a flop like that?

[AllIn3High]

I'd fold.

Fold, with such little action preflop he could be holding anything... suited conectors etc.

I'm not sure if that was english.

It seems like he wanted to slowplay his set because the board probably doesn't look all that bad to him. Then he got excited to see action and pushed. If he pops up 89, so be it.
