hi

lets say my opponent risks 9bb to win 4.5 preflop. so i need to defend astleast 33.333333333333333333333% of my range to not get exploitet. i heard that its needed to defend more than 33.333333333333333333333333% to not get exploitet when facing 3bet in position. for the case this is true, do i need to defend a even higher percent of my range when faacing a 3bet OOP?

thx
