I like it as you played, but betting harder with my whole range on the turn.

Preflop is OK. Its not a manditory 3bet at lowstakes, but a decent hand to help balancing the rest and stronger part of your 3betting range. 

Flop 3way I'm torn between bet/folding and checking, and its hardt to say which has more merit. I think this should hit BBs range often enough for it to be ok to slow down, but at the same time you nail it as well (uour range that is), and I do not expect to get blown off by a bluff 3way. 

If you check, and someone bets, i might lay it down. Too few nutouts, OOP and a problem getting payed off when hitting, since your outs are "obvious scarecards".

Harder betsizing OTT as I don't often bluff here after checking flop. If someone raises, it comes down to gutfeel i think

BB was shallow in this spot and i was going to call his shove.

I decided to bet turn considering that BN folds frequently. He had the last word otf and would probably stab against checks with his pairs and wraps. Hence this 9 aint help him that often. Meanwhile BB seems to be weak player with pretty wide range otf to check and to shove ott. 

i'm betting flop. call bb jam and fold to btn jam. 1/2 pot and firing a lot of turns if called.
