so for roughly 50% open i calculated that i needed to flat 120 combos. from a GTO standpoint my BTN 4bet gin value range is really wide, so i'm left with some not so great hands to call a 3bet with (technically 77+ ATs+ AJ KQs 'should' be in my 4bet gin range, if we go strictly according to MDF given some standard raises preflop - see DONKR articles for more info)

if i'm up against really tight 3bet ranges hands like ATo and KQo will be dominated more often - they do better versus villain's with light 3bet ranges. Do i still defend as many combos but choose hands with less proximity affects such as suited connected type hands or do i exploit their tight 3bet range by folding more?
