I currently only play 100nl but just going to ask here since I think you guys would give better insight. I started watching some coaching vids recently which is why I'm starting to question whether or not my preflop strategy is the most +ev vs these opponents. I've been playing profitably for a few years now at low stakes and ik this question seems contradictory to that since its one of the more basic concepts its just I feel as if I may be missing some value due by not fully understanding how to adjust my starting ranges in these spots. So I'll break this question down into 2 parts, first being isolating ip, and second being how to adjust our opening range (and possibly sizing?) when we have high vpip recs ip on us.
Part 1: Isolating calling stations (and stealing blinds from calling stations)
So first lets assume we have a 60/10/2 type of fish who is a calling station postflop as well as preflop (say 38% wtsd, 1.5 total AF), they limp in before us and we're on the btn with 2 regs in the blinds (100bb eff stacks). My standard RFI range on the btn vs 2 regs generally looks like this (note that I use 3x open vs regs in blinds +1x per limper hence the tighter range),
with said rec player who limped in before us my isolating range on the btn would look something like this,
my reasoning being that we have less fold equity postflop so our weaker 'drawy' hands lose value whereas our high card hands go up in value. Though I see an argument to be made that we have more implied odds with our weaker drawy hands so I'm wondering if I should not be omitting the hands which I do? If not then should I keep all those hands as well as open the rest of my range as I did?
I have a similar line of thinking when attempting to steal on btn vs a similar rec player in the BB.
Part 2: Opening range adjustments with calling station ip vs us
So for this part I'll use the same player from the last example. This time we're in the co and he's on the btn, and 2 standard regs in the blinds.
My standard co opening range looks something like this,
whereas given said situation it would look more like this,
Given that I'm tightening my range on the co should I increase my raise sizing a bit? I've heard someone say that they'll be opening wider in this spot since its less likely that we get 3bet, this makes sense also.
So I'm hoping to get some insight from you guys as to what the most +ev preflop strat is vs these sort of players in similar spots. Not to sound like a douche but please only 100nl+ winning players only, I see lower stakes players posting advice which seem to make sense but is -ev in practice and as this is kind of an 'open-for-debate' kind of topic I don't want to be thrown off and led to believe something which would be -ev.
Look forward to hearing your opinions, thanks
