[BluffTHIS!]

Dave,

It is true that you should often just take the free card in position to avoid the possibility of being checkraised and to lose less if you don't hit and are up against a calling station who won't be bluffed if holding any pair for small money. I frequently do the same. However I stipulated that the opponent was not a known slowplayer/checkraiser. Also I play good draws aggressively in position just like I do sets.
