After the 2nd part of this analysis, my next 2 videos are on SB strategy and specifically stealing vs. limping. I think you'll find them interesting for sure. 

I play 100NL as well. I have started experimenting around with limping the SB, I think your right that alot of villains are not defending there BB enough. There are definitely quite a few villains you can open ATC BvB and auto profit. Against some the villains that have tighter defending ranges( folding ~50-55%+) I open. villains who are defending wider than ~45-50% I usually limp. You need quite a few hands to get a significant sample, and im more inclined to open when my sample is small and I expect villain to be close to the 50-55% folding threshold in order to gain more data. I play some ring and some zoom games, I think for zoom it has the added benefit of making your SB open range appear a lot tighter than it actually is on villains HUD.

It's closer for sure.  We do have a good amount of value hands there that feel good about VBing against his strange line that looks pretty weak.. (88-AA/7x) Which means we can bluff a good amount as well.  In fact there are times in poker when CHKing is +EV because you have good SD equity.. even if you're 80% sure you're going to win the pot.. but bluffing is better because villain should fold his entire bluff-catching range.  (Plus your VBs don't get paid if you're not bluffing enough, so you need to have some bluffs.)  This isn't necessarily one of those spots, but I do feel like K/Q-high win sometimes at SD yet also feel like there's probably more value in getting him to fold A/K/Q-high.

Yah that seems reasonable.. but I think you'll find at the higher stakes (not sure what stakes you play) that players are more inclined to take advantage of you if you're isolating fish too wide.  Thus you might not be able to iso-raise 97s/JTo type hands but limp > fold > raise.  I think this is the *most* useful at a table where the game is running due to a fish.. ie. everyone's attention is on the fish and thus you won't get away with iso-ing him/her too wide. 

Getting CRd is close.. I think it's a spot where I don't expect to get CRd very often (neither player has top two sets.. and possible never any set).  Which means CRs are going to be very concentrated on draws (of which there are a ton) and against which:  (1) our equity drops because we're often dominated and (2) our value when we hit drops because of big reverse implied odds.
