I have problem with calling down bluffs because
at my level 25PL/50NL players change so much.
So I dont find very much value doing so.

I mean betting/calling mid pair against fish/maniac is
not bluff its for value


I have noticed that regular sharks in this level
respect each other very much and dont get into
marginal situations. When regulars do battle
they are usually set vs set or AA vs KK situations.

But if I call regular PF raise with AQ off and I dont
hit the flop I usually fold to his Cbet.
