Generally, we don't want to have a flatting range in SB versus CO/OTB when there is a reg in BB (because he will have good odds to flat, and he can squeeze often, and the fact to be OOP w/o initiative OTF...).

But when there is a weak / loose player in BB, or when a guy has limped, how it changes our 3B range ? Do we want to flat more hands and 3B less in order to play a maximum hands versus BB ?

A 3 linear 3 betting range SB vs OTB looks like 55+, Axs+, AJo+, KQo, T9s+, J9s+, QTs+, KTs+.

Do we want to flat almost all the broadways, Axs, add 22-44, and just 3B like TT+, AQ and some bluffs like K9s-K2s versus OTB or CO ?
