I tend to find villians at these stakes 3 bet too much in these spots or dont 3 bet enough. The best way to exploit that is 4 bet with a wider range. Hands with blockers that play well postflop if called are best. For example A2-A5 suited and occasionally flat a lot of your value range and broadway type hands/suited connecrors. This will make you more difficult to play against. Also check out poker snowie preflop ranges for a GTO spin on ranges in this spot.

What so you mean by pop tendencies? If you mean 3 bet range from blinds then i find that most villians will 3 bet button with any ace a2-ak suited and offsuit and k10+ as well as their obvious value range. I also tend to find most villians dont flat their small to medium pocket pairs and tend to 3 bet them against button open. So 22-77. This is just a general rule of thumb against uknown villians. Also i play 6 max not full ring so this could vary in full ring games maybe a little bit tighter 3 bet ranges in full ring games where villians are nittier.

W hen you c bet you will get floated a lot more with air by regs in position who will try and take it down in later streets if you show weakness. One way to exploit that is double and sometimes even triple barrel your hands. And check calling/ check raising turns and rivers with your made hands as well as bluffs vs aggressive players. Likewise its also important for you to float more flops and turns with a wider range as you will also get double and triple barelled with air as well as made hands. If you get raised large on the river it is normally the nuts/a made hand. Dont stack of light there. These are just a couple i can think of from the top of my head. If i think of more ill let you know. In general although there are some good regs most players at 25nl suck. There are plenty of fish and lots of bad regs. Most of your win rate will come from value bets. Learn to value bet wider and bet for thin value on the river.

After playing around 150k hands or so thats just a general feel that i got from 25nl.
