The small stakes forum does a
SS Digest which compiles interesting/good posts from that forum each week.
2+2 recently added a
Posts of the Day feature which I think features the highest-traffic posts of the day.
The
archives archives are an amazing (and under-utilized) resource. The various subforums seem to ebb and flow in terms of which has the best strategy. For a while (two years ago?) the small stakes forum was bar-none the best strategy forum on 2+2. After that HUSH was the best. Then mid-high PL/NL. Figure out which posters know what they're talking about and scour the archives for their posts; they're worth their weight in gold.
