from the sb against btn? Almost never unless they were just folding wayyyy too much to 3bet
or do you mean the bb against the sb? There you can play wider for 3bet vs guys who open too wide/fold too much to 3bet or call vs guys who cbet too much and c/f turn or miss a lot of value bets or have a low cbet frequency and subsequently high flop c/f stat.
One area that sometimes causes trouble especially in 6 max where someone appears to be stealing way too much but also doesn't fold to 3 bets very often and it feels wrong to keep folding but also wrong to play back with junk.
