Why not just make a more profitable play (check) and get the same information?

Obviously there are people at 3/6 who can exploit a b/f line in this situation. Chasing a draw against a bettor with a pair is such a common situation, and if you can c/r your draw and get the bettor to fold just some of the time that is so incredibly valuable. If I see someone pull a b/f line I instantly take a note on this player. So I would exploit it, and I am probably a loser at stud 3/6...
