The btn is a decent player, but nothing spectacular as you can see by the min-raise. He has min-raised before in this situation, at least 1 time.
The other player is a very good player.

I would push here with AJo, but A9o I didnt feel comfortable with. But when I thought about it, AJo is almost the same as A9o .. so if I would push with AJ why not with A9? Is this a situation of "loving the face cards" ?
