Now I am wondering what you guys think I should do on the river (I will reveal what I did and the process behind the decision)?

Some more info on the thought process throughout the hand: Preflop, when villain makes is 4bb to go from MP we can be fairly certain that he has a premium or very strong holding (more weighted towards premiums as it is a common tell in the micros to overraise with premium holdings either, or the person may have been watching Blackrain videos about the micros thus assumes no intelligence), and hence we can assume we are likely behind and thus elect just to call from the SB (given we have no previous information), and the hand becomes more interesting when the BB comes along for the ride. On the flop we have flopped top two pair and thus are loving our hand, we decide to check to conceal the strength of our hand assuming/hoping that somebody might bet such a wet board (especially the preflop raiser who's range hits the board pretty hard). The PF raiser elects to bet just under half pot on the flop, It doesn't reveal too much about the hand, he could generally be doing this with his entire range in the spot, we consider raising, however, with such a strong holding and the BB left to act behind us we elect just to call hoping to not kill action from the BB. When the BB calls we put him on a wide range KQs, KQo, JTs, JTo, Axs,Axo, 22, 88-1010. On the turn we elect to check realizing MP is pretty pot committed at this point, and it checks around to him when he elects to shove we elect to simply call again seeing if we can get action from BB, when BB just flat calls as well we weigh his range towards flush and straight draws such as KQs, JTs, as well as a set such as 222 (as I assume he would 3bet JJ+ preflop), while not yet eliminating A10+ from his range (although the range is definitely not weighted towards A10 it is still the micros). The river comes and I mess up a hotkey while I was mulling over the question and ended up betting 35% pot (having not come to a final decision on whether to bet or check and how much to bet), although I don't mind this bet, it does strongly weigh my hands towards value hands such as two pairs and sets on this board, while also potentially inducing bluffs given the sizing, however, once villain elects to shove what do we do. We are getting 2.98:1 odds on the river. I will reveal my action after some discussion.
