What should be a good 4bet range?
I use some times hands like ats kqx a2-3-4s in my 4bet range vs people who over3betting but I don't have exactly ranges of which hands should I 4bet with

Do you think the bluff was good?
I have all the qq kk and aa in my range and I want to put pressure also I dont like the 1/3 in this board texture OOP and with my hand equity I decide to fast play with 1/2 and shove on a safe Turn
I expect him to call hands like kqs jjs QQs Akx Aqs (i cant see other hands in his 4bet calling range help me with that plz)
