Hi guys,

I've been playing NL25 zoom (antes) lately and have noticed I'm folding too much to 3bets and 4bets. In trying to fix this, I've reviewed my 4b and 5b shove ranges. What I'm wondering about are some common default approaches to this spot vs. mostly unknown players, i.e. how to modify solver ranges to account for pool tendencies. For example, when I have a polarized range and raise in position (RFI, 3b, or 4b), I'm trying to defend about half of these and build a balanced range around my premiums, generally with suited blockers. But if an unknown is never 4bet-folding, bluffs make no sense. Is there a shortcut to approaching these spots without waiting for enough stats to come in?
Correct me if i'm wrong, but I think recs 3b/4b/5b too tight, compared to solver ranges. And if someone is reraising too tight, then carefully constructed and balanced continuing ranges are just getting exploited on later streets (or not maximizing overall EV) by very strong and never fold. For example, if their 4b range on the button vs. my SB 3b is too tight and value-heavy (say top 3%) and never folds, then in theory I should be happy to overfold to their 4bets, and never 5b bluff.

Once enough hands have been played and I can get more robust stats, adjusting would be more reasonable, but some practical advice would be much appreciated on pool tendencies and a general approach. My current thought it to stay tighter vs. unknowns until they show aggro, reg-y tendencies and then to default to a more balanced approach (so first old school Harrington; then GTO/Monker, then adjust based on stats).

Any advice much appreciated.

Thanks in advance!
