Nice volume!
1) I would fold to 4b because of his sizing - he is directed towards (?
) value and I think you can exploit that by just folding - it will be very tough play OOP without info and if we assume he calls QQ probably and 4b AK,KK+ and some bluffs (KQo ?). btw. you could have bigger sizing. As played I would play same.
2) Donkbet/fold turn, but I think you could fold flop as well and spare your mindset and money, it is close spot.
3) Fold turn, belive to second barrel if no info - playerpool read .
