you have 80k, 15k in preflop, 15k value bet postflop, now your down to 50k and if you call down to 35k. This is definitely either a push or fold. I would push. Range of villain could literally be any pocket pair, (but since you labeled him TAG and he called 12k preflop I'd say minimum 77 or even minimum 99), AK or AQ (AJ possible but not as likely for TAG) and possibly a broadway suited connector like KQs or QJs (QJ probably not as likely for TAG).

The hands with J in it I can not see TAG playing, especially against another TAG. The more likely of these holdings is AK, AQ, KK, QQ or JJ (JJ would play slower than this, most likely). The question is based on this do you push or fold. I probably push and get busted out.
