Open size is not standart, especially OTB and especially at micros, because of high rake you should increase your sizing, it will effect how wide BB will defend by quite a bit, so I would at least 2.5x it.

OTF after min raise, you should be very careful, because BB will have all offsuit str8's and you won't, he will have most sets, and many more 2p's than you, so betting frequency in such spot is likely to be like 30% or so, decent amount of overpairs and 2p's should mix check backs in this spot. I think 77's can mix in some bets, but still mostly just check.

Turn bet seems like a big punt, you're not getting called by worse enough nor have enough backup equity to justify betting, plus you're not getting better hands to fold with such sizing, at least bet big then if u're bluffing so you may get some folds from better hands, and decrease raise frequency from BB

When I read the thread I wondered whether you bet for value or as a bluff? In spots where it gets blurry, it's probably a good idea to consider a check. In this spot on the flop, I would check and see what develops. You have some showdown equity and an OESD, so quite some runouts will be fine for you.

I think the same applies for the turn spot, just more pronounced.

Thoughts on checking back flop? Seems like it's a good spot to call Turn and you don't want to call a flop check raise.

I was pretty much going to comment exactly what DNegs98 is saying - you want to give your opponents a chance to bluff and you don't want to get raised off your medium strength hands. The "overcard scare" mentality kind of goes a way once you play many hands of holdem as you get more familiar with how often your opponents have air vs how often their overcards are hitting. It's less of an issue than you'd think. In other words, when they bet turn after you check back flop, they have bluffs more than they have hands that hit something on the turn (on average). Hope that helps.
