Questions about HU in general

[DennisGPunkt]

Lately ive been playing HU on PS (10+5$) and ive run terrible. Besides ALOT Badbeats, ive been running into the following situaton quite often.

As soon as i grinded up a 2 to 1 chiplead people start randomly pushing (blinds at 3rd level). Now I wonder wether i should call with med PP or if im better off folding? I've
lost like 6 HU in a row beeing up against such players and i wonder if my play there is right when im calling those bets.
