Nits are used to play good hands in safe spots. Increasing your Cbet percentage leads to more bluffs in your ranges, so they will have to start evaluating how you play not to fold too much against you. This mean they will have to calldown more hands, including some bad 2nd pair and stuff like that. Most nits in NL25 are totally impotent when it comes to adapt their play postflop.
As a midstack, it is even harder for them, since the (often poor) experience they have in postflop play is based on bigstack-type implicit odds, which they DON'T have against you. They will as a result make a lot more mistakes.
I am a bigstack player in NL25 SH, and I'm really interested in MSS since this would help me grinding the limits (while having a good feel in both styles I could get som shots in the upper limit in MSS before moving up in BSS. I will also use MSS when playing live in casinos, so that the bankroll management is easier). I have a strong experience in the (RIP) SSS which were totally about cutting down the opponent's implicit odds and getting the money from the limpers (since your play was almost "perfect" as for the ratio between the number of hands played and the number of players, you got your money from the imbalances at the tables caused by players putting to much money in the middle. You could as well enhance that imbalance by stealing blinds, adding a few BB/100hands, and resteals, that get necessary when moving up the limits since less players will throw money in the middle for you to win by raising)
I am particularly interested in the MSS because it still have some of that "implicit odds kill" stuff present in the (RIP) SSS, and at the same time allows some (simpler compared to BSS, but still) postflop play, which means occasions to outplay your opponents (but also occasions to let them outplay you! Allways be careful!). Your postflop ranges have to be fed by some bluff percentages, more or less depending on the tables and opponents.
Since SSS is dead, it is not possible anymore to earn money against anyone in microlimits without playing decently postflop. AF is really an important stat to work with, especially coupled with the WTS value. Looking at both will help you see is your opponent has some tendency to slowplay, being overaggressive, controling the pots too much (quite common in NL25 in my experience) and therefore not extracting enough value from his hands (think about it: one more called value bet (by your opponents) every 100 hands means +2BB/100hands in unraised pots.)
I personally pushed this to the extreme: I now use 3 AF values: AF(flop), AF(turn) and AF(river). Most players in NL25 have those AF poorly balanced (even if their average AF seems good), and are therefore easily exploitable.
Well, maybe I wrote a little bit too much for someone who came to ask a question? I won't delete the above text since it might (imho) contain some useful stuff for players.
Does anyone know where I can find useful things about advanced MSS (I'll get access again to the gold articles tomorrow I think, since I generated enough strategypoints this weekend). Im looking about advanced stuff about odds and tuning of the preflop hand ranges, the use of pocket pairs and suited connectors (as I told earlier, I am a SH bigstack player, and an aggressive one, but I don't want my SH tendencies to curse my MSS play). Maybe some things about the aggressive preflop play (3bets and 4bets(shove?), because I think the halfstack changes a lot of things about the odds there), and of course MSS in shorthanded games.
I will add that I plan to start and train MSS one limit under my actual one to get a feel for it in an envirronment I already know I crush. I don't think steals and resteals play does change a lot from BSS, but if so I would be interested in some informations about that.
I'm also wondering about a looser MSS strategy, but I'm not really sure about it's viability (at least for me) since when I loosen up I do it by playing around the implicit odds (not really clear maybe but it's hard to explain, whatever...).
Maybe I'm asking a little bit too much, but any informations about all that will be really appreciated!
Thank you.
