ok first post hope it works. i have noticed that the exact same thing had happened to me previously but have pretty much stopped the stone cold bluffs. when i first started i overrated the stone cold bluff and used it every 5-10 hands, midway through a tourney, but never early. i noticed that i ended up losing plenty of chips and ended up fighting back for chips. i believe that it is easier to bluff into loose players however, it is your preference. well i think i 've said enough for a first post.
