I would like to start a discussion about play from the SB because I am getting a bit confused in that spot. I hear so many advocate that we should either be 3betting or folding a lot from SB. The arguments for that are usually that we if we just call the BB will most often come a long and we will have poor absolute and relative position postflop.

Yet, I see Phil defend so often with all kind of hands from the SB in his videos. Hands like weakish KK and today a QJ96ds vs a MP open (from a kind of loose player).

If we have a pulling hand like weakish KK or As9s8c6h I would argue that just calling is fine as long as we are playing against a medium/weak range. We have too much equity to fold and many of these hands don't play that well in 3bet pots oop. Is the fact that the BB can come along with a weak hand really enough to make us want to fold or 3bet these hands?

And when we are playing against stronger ranges like top 20% is it really bad to defend with a hands like AsKsTh8h? This would be a hand that I am not crazy about 3betting vs MP range but feels too strong to just fold.

Anybody have any input on when to flat and when to 3bet from the SB? How much is the strength of the opening range a factor? And how much is the player type in the BB a factor? I mean if the BB is a big fish I would think we don't want to force him out of the pot.

Looking forward to any input.
