defending little blind when structure is 2 chip, 3 chip.

I think this mostly depends on the BB. In a normal blind structure, you're wanting to 3bet because your equity is higher HU than 3 handed with pretty much every hand you would consider defending the SB with, so you want to raise to try to isolate the stealer. With the 2/3 structure, you're going to want to defend a wider range of hands (probably around 30% or more(I haven't done the math tho)) and you're going to want to put in a raise if you have a good chance of shutting out the BB. If the BB adjusts to your wide 3betting range and he starts CCing or capping light, you're probably going to want to start cold calling your weaker suited hands that play well multiway. Once you start cold calling, you're going to want to flat call sometimes with AA, KK, and AKs for balance.

Same range to defend vs a raise, 3 bet and force the bb out as you would in the normal structure. To 3 bet or fold you need a fairly big hand to play in the first place, the good news is when you do win you'll win slightly more money. The difference in this structure is that you defend with virtually any 2 cards against limpers and of course, as you state above, you can defend the bb slightly more liberally.
