25NL, A9s in Blind Battle, Villian's 4bet is a push

[KickerNotch]

Villian has played solid over the past 15 hands and has shown down some quality holdings. I've been playing a bit looser than usual preflop but haven't gotten too out of line post flop even though the ale is starting to kick in. I'm dealt A9s in the SB and it is folded around to me. I had a strong suspicion if I completed villian would two bet and I would reraise. The only hitch was villian pushing which was unusual.

4 folds, Hero calls, <font color="#cc0000">BB raises to $0.5</font>, <font color="#cc0000">Hero raises to $2.00</font>, <font color="#cc0000">BB raises all-in $69.2</font>.



In general what hand range would take this line by the BB and if this is not worth calling by Hero, would villian requesting time before pushing preflop instead of insta-pushing help Hero's decision here?

Villan's range can be anything in 25nl over 15 hands. But still, easy easy fold with A9s
