1) I don't mind preflop because you have position on a tight 3bettor. Postflop you can fold comfortably.

2) Super standard vs donk.

1) yeah its fine, only semi gut-wrenching to me
2) i'd fold it live

1) calling is ok but i'd be more inclined to just fold vs someone this insanely nitty, yes fold is good postflop.
2) cool
