I play pretty much the smallest stakes games around but I've recently found myself transitioning to a more lagish style of play and it seems to be more profitable for me. I came to realise that by opening up my range and playing more pots with fish I gave them a lot more opportunities to make mistakes. The improvement was largely because I developed a much better post flop game and some factors really improved my winrate by a ton.
1. value betting way better than I used to. I now value bet a shit ton more and a lot more thinly than I used to. why worry about pot control when they will stack off bottom pair?
2. Reads. I've come to realise that most of the micro players are blatantly easy to read when it comes to bet sizing and timing tells in relation to the board texture and action.
3. Note taking. I play a lot on 888
which has a small player pool which means that you will quite often see the same regs over and over again, this allows me to gain a lot of information and even though these players are "regs" they are used to playing terrible players and play a style that works for them but is highly exploitable if like me you have info and are capable of adapting your play. Against these guys I end up exploiting them more than the fish in a lot of cases.
4. Just paying attention. I know you aren't meant to bluff at the micros, but if you just play attention you will find that you can pick up so much info on payer, a lot of them are even capable of folding allowing you to actually on occasion bluff if you do it correctly plus you can suddenly pick up when one player goes on tilt or is making mistakes in bet sizing/ always taking some weird line which you can punish if you notice.
4. Folding! This is so big, but somehow it's now become tremendously easy to fold hands that I used to either get too attached to or would only fold reluctantly. Overpairs are now easy for me to fold since the players make it obvious when I'm beat. two pair top pairs I can now fold these hands so much easier. I don't know how I know the difference but I seem to just always have a much better sense to know when to make huge folds but at the same time I'm also making a lot of (successful) hero calls. I think the difference is just experience.
I'm also now a huge fan of punishing limpers relentlessly and also 3 betting a pretty wide range. I've found that a lot of these players are making so many mistakes post flop that by taking the initiative in the hand in bloated pots I'm winning bigger pots when they make those mistakes which allows me to win more pots and even gets me payed off easier since if you play long enough people start to notice you play quite a lot of hands (but mostly just late position!) This even gets you payed off easier and occasionally gets people to blow up after getting fed up of you constantly raising their limps 3 betting them and just not letting them have any easy decisions, this is great if you can make a real hand when they do blow up.
Basically I've found I can outplay my opponents so I play with them more. I suspect it's just experience that has got me playing so much better now, plus a better mind set. This isn't to say that playing lag is better, especially at the micros, it's just my story that I felt compelled to share, everyone is different and what's good for me might not be good for you. Because the key point with this style is that you need to be sure you are making all the correct decisions post flop. I do come up against a lot more marginal spot and more high variance spots, but I've found I can handle these quite well.
