never slow play, thats the only advice i have on this hand, even if button is LAG its still just a guess, dont slowplay ever, GL

Bet, bet, bet. You make money at the micros by value betting your huge hands (which don't come often). Don't get fancy or trap, just bet bet bet. As played you could make an argument for raising the turn, river is just a check back.

This is a super easy spot for bet, bet, bet. Even if BU 'had a tendency to bet' he's far less likely to do that three-way, plus it's not like you flopped quads on an AA2 board. The flop offers a ton of draws and top pair type hands you're not blocking so you're most likely missing a ton of value with a check. Lastly, micro stakes players are notoriously bad at putting a lot of money into the pot so unless you're playing against a confirmed maniac that's extremely happy to stab at every pot just bet big when you want to get paid.
