i think i'd fold. he is obviously not good so stuff like 45s, 46s, 34s are def. in his range. also in his range are Axcc, 35cc, 44, 22, and possibly 99 but pretty unlikely. kk/qq aren't totally out of the realm of possibility but fairly unlikely i'd say.

prior to his river bet the only stuff you're beating is like 35s or lower pocket pairs, and i highly doubt lower pocket pairs push the river, and 35s is really only one hand in a multitude of many that beat you.
