On the turn, I would suggest putting him all-in. Think about it. The pot size is $0.85. You got $3.34 while the villain's got $1.42. Pot size here is pretty much putting him nearly all-in. Just raise it to $1.42, which tells
the villain that you're trying to put him all-in. By raising 25 cents into a pot of 85 cents, not only is he getting nearly a good price to make his flush or straight, he will have good implied odds of getting rest of your chips. By overbetting, you protect the pot and leave yourself with no decision to make on the river. At microstakes, players are very capable of calling all-in bets with any wide range of hands, such as any Ace, 78o, 47o, flush draws, middle pairs, even possibly gutshot draws(because I have seen worse).
Another thing, although it didn't matter in this hand since villain was shorter than you, put auto-rebuy on. I know it's hard to do but you want to maximize your win rate while not remembering your wins/losses as it'll affect you psychologically if you don't have it on. It's gonna suck so much when you lost a huge pot that cripples your stack and then next hand, you're dealt pocket Aces or a flopped set. I had a hard time getting in habit of auto-rebuying but in the long run, as long as you have good bankroll management, you shouldn't worry about keeping track of losing few blinds. If you have Holdem Manager or Pokertracker3, it'll help you keep track of them anyways.
