i check. i think his range is something like KK-99,AJs+,AQo+. he didn't have to reraise immediately with big pocket pairs planning to raise the turn until the 4 came, but just in case, i discounted AA. even if he calls with all of this range, you are a 62:38 underdog. you can tweak the range some more but i doubt you have a valuebet here.

EDIT: ok, i discounted the pp's even more down to JJ-99. you are still an 54:44 underdog. and don't forget he might have been trying to slowplay a set (unlikely though it may be based on pf) and decided to just call down once the scare card came. also he doesn't have to call with AJ or even AK, which makes us even more of an underdog against the range of hands he calls with.
