PS 4/180 - Bet river for value?

[All_In_Olly]

Early in 4/180 and no reads on villain.

Comments on all streets welcome.

Is pre flop call very bad?
I don't usually call a raise pre flop with Axs but did this time because of the caller and my position.

On turn obv calling is fine because of immediate odds, do you raise even though he's shown interest on the flop?

Main reason for posting is river decision - is a raise standard?
If so how much?
And do you fold to a raise?
