i mean if his show down stats are as nitty as his PF ones then i think it's profitable to shove here. again assuming he's a complete nit, he folds 99 and JJ+ here which is 25 hands and calls with all of his sets (12 hands) and unless he's double barrelling with like AK or AQ (which he isn't) then those are the only hands he has. so we have >67% fold equity and we have 6 outs against any of the hands he's calling with.

EDIT: reread the HH and realized that he doesn't have 33 here very often, so he's only calling with 9 hands (one more time, assuming he's as nitty postflop as he is pre)
