I play turbos between 22$ and 55$ on pokerstars. I’m not so confident at the higher blind levels 25/50 and 50/100. So I have some questions:

1.) I am the Big Blind, villain opens with mini-raise (2BB) at the levels 25/50 or 50/100. Which calling range would you recommand? Are e.g. K6s, Q6s , A4, small SC calling hands?

2.) In case of calling the mini raise, how should I play the flop , if I have:
- middle pair
- bottom pair
- Ace high
- a poor draw like a gutshot
- air, no outs
In which Situations or against which opponents should ich donk bet, check raise or check call. What do you think about bluff donk betting and bluff check raising on dry board like K?
72 rainbow?

3.) Generally, should I play more or less aggressiv than on the first blind levens
