So I'm still struggling with this in general... Assume no reads except not a raving loonie. 100bb effective stacks.

I have QQ UTG. PFR 4x. Flat called by CO or Bu. Blinds fold.
Flop comes Axx. Based on reading a post specifically on this sh!t (ISF I think...? It's referred to alot, just don't have the link handy), I know check/call this so as not to fold out weaker hands. So assume I check, Bu 3/4 PSB.

Assume a blank hits the Turn. Now what? I still could be drawing dead. Do I go into calldown mode, and if so, should I be willing to call a 1/2psb+ turn bet as well? I can't really donk out and rep the A on the turn, so I don't see what good that does on a brick.

What I usually end up doing, is calling the flop bet and folding to a turn bet. Or if Turn goes check/check, I'll call a reasonable River bet on another brick.

I'm trying to figure out the line between being a calling station drawing to a two-outer and being a weak-tightie getting pushed out on bluffs.

Any suggestions on approach / thought process (or links to other posts that discuss this) would be helpful. Also, if I'm just not giving enough info to get a reasonable answer, pls let me know what else (besides detailed reads...) I should be looking for. Thx!!
