It think everyone agrees that it's correct defend close to 100% on the BB but what are the min requirements in SB? Of course pot odds are much worst and there is player left to act but where do we put the line ? 30%,35%,40%?

More specifically

BTN opens 50% to 3,5x
BB is a reg who SQ 5-6% and will call 80% of the time if you call.

What would you do with the following hands

JJT5$ss ?
ATT2$ss w A hi suit?
AT95$ss w A hi suit?
KQJ7$ss ?
9987$ss ?
8876$ss?
QT76$ss ?

Would you change your strategy if BB folds 50% of the time?
