re: Poker & Range for calling/reraising blind steels
Totally agree with what is being said about table considerations, but let me go off in this direction for a second.
I don't think you want to look at it as "loosening up your range". You have probably read something and heard about defending your blind. Pretty important concept in tournanments, but not so much in cash. So don't get too hung up on it in cash - it's just the price of doing business.
Now having said that I do have an answer for you: You need to have a hand you are willing to go to war with. This will mean different things to different people (kind of depends on your postflop skill) but for me I could do that with something like 9Ts. If I have that then I am coming over the top of his raise (I mean if it's really a steal then he probably doesn't want to go to the flop anyway - see below). I am not doing it with a suited gapper (unless there are like 5 or 6 people in the pot already). Just be holding something that you have a shot with on the flop. K8 is really not one of those (but again it depends on the guy putting the pressure on).
If this is truly a blind steal then that guy isn't too concerned about his cards. He figures 1) he has position and 2) he is repping something with his PF raise so after the flop - wet or dry - he can continue to rep and take your money, even by coming over the top of your c-bet. If you do not have the steel to get in this kind of confrontation then you probably just need to fold PF.
Remember, you are still out of position,even though you act last PF. If you are playing hit or miss with the flop to take him on you just can't broaden your range much at all to do this.
It again comes down to having a plan before that flop hits - whatcha gonna do? You are first to act.
