Q
UTG raises to $0.30, hero???
i've been thinking recently about this situation and i'm not exactly sure about it so i created a sample hand
villain is 20/18 reg over 400 hands, folds to 3bet 75% and opens from UTG 13%.
generally vs this sort of player i'd be flatting IP with AK and QQ because a lot of the time if they continue i'm not doing well. that also means i'm 3betting KK and AA only. should i have a bluff range here? if so then i was thinking it would be best to pick a hand like KQ since i can't really call an open with it and it's at the top of my folding range and it blocks QQ/KK and AK. or is it not a good idea to have a 3bet bluff range vs a UTG open?
also, what about different positions at the table? because obviously it's not such a good idea if there are whales behind us since they will cold call our 3bet bluff and UTG will be in a fun spot. but if i were on the BU for example should i be more inclined to 3bet bluff or does it not make a difference?
