Hey, ive been struggling about my 3bet range in HU sngs and i really dont know what should be a good, standard 3bet range kind off balanced aswell (i mean not only valuehands spec. not vs regs who will realize it in no time. Im playing the 22$ HU's, so i guess advices that will help out in 10$-50$ HU's would be very appreciated :)

Anyway.. My questions is kinda random picked out what i think i need to get better at in my own game.
- 3bet range versus a minraisar (lets say he mr like 80%+) what kind of range should we be 3betting here, i just feel like i make it easy for FI sometimes by just calling pre instead of 3betting it making his life harder.
-3bet range if FI is 3xing? lets say he is like 65% pfr, 15% limp and the rest he is just folding or something like that.
-isolate range vs a limpfish who just continue limp after limp after limp, i mean we could go for only valuehands etc and hands like QTs which plays well postflopp etc i guess is good vs thoose players?
-And what stacksize (BB x) do you guys start to repush kinda "light" vs someone who is really putting pressure on you? like lets say 25/50 blinds and he is minraising almost any2 seems like to put pressure on you? (oh and also.. what hands should we be repushing at what X bb stack?

I hope my questions wasn't way to weird or anything like that..

offtopic: much difference between the 20$'s and the 30$'s HUs on ftp if anyone recently switched?(whats the biggest difference if thats the case?)

Hope it wasnt just way too much questions feel free to answer just one if you feel like helping out:)
