its a nice startegy for 9hnd tables, however in shorthanded play this will proove a poor strategy in longer runs i think.. people will notice your tight play, and outraise you a lot with rag hands.
it can pay out, but it can also bite you in the ass... and remember.. when you finally get KK...
an idiot will call you with 7 8 suited and win
so be carefull, and try to switch your styles up from time to time.
(every 30mins or so @ cash tables)
