The only really affective way to beat a short stack is through good notes/reads.....
Notes/reads will tell you if they are plaing SSS or just a fish buying in short/not reloading when they lose chips. The fish are treated like normal fish...
Notes/reads will tell you if they are a basic SSS, or working in advanced SSS techniques. Knowing they will only play AA,KK, AK in EP or knowing they will only re-raise JJ+ ect can only be found out from notes and a large amount of hands.
Notes will tell you if they are mass multitabling for 4 tables or 16. A 4 tabler might be new but also might be advanced with concentration on less tables....only way to know is through notes\reads.
Notes\reads will tell you what level of blind defender they are to stealers. Which can come in real handy when sitting directly to the right of SSS'rs.
I can go on for almost every aspect of NL poker just like an other style people play....
In the end, you can choose to focus on beating SSS players or you can ignore them to focus on all the other fish that play short or deep for that matter. There is so much other money at the tables that you can pretty much avoid SSS'rs all together if you really want to....
As a side note, it is much easier to pick out other styles of SSS if you are proficient at it rather than trying to figure out the tricks if you just know the play premium hands with 20 BB.....
