I hate hate hate that flop reraise
If you think he's testing you...just call, see a turn, control the pot and its good because if he's bluffing you don't want him to STOP BLUFFING at you.
BTW- just shove the turn, that weakish turn bet sucks arse
PS- PF raise really isn't standard and if you are losing your stack on these situations, maybe play tighter in EP
