Hand 1 (KK)
Your 3-bet size gives away a bit of a tell. You put in more than 1/3 of your stack, which mean, you committed yourself to the pot. You can not fold to a 4-bet, and you can generally not fold after the flop either. This mean, you can never have any bluffs, and the opponent can also not
bluff you. It might not be a big deal in a 2$ tournaments, because most opponents are to bad to even care about, what you are doing. But when you move up, this is something to consider. On the flop I like checking. There is less than a pot sized bet left, and you are never folding anyway, so why not allow him to hang himself or catch up. When he flopped a combo draw, he is of course going with it regardless, and it just is, what it is.
Hand 2 (J9)
I think, you overplayed this hand. When you pot the flop and jam the turn into a whole school of players, you pretty much make sure, you only get action, when you are beat. He did in fact call you with worse, which is kind of crazy. But again speaking about moving up, this is not something, you will see much, when you get to for instance 5$ tournaments. So you might as well start practicing some theoretically more sound lines and bet sizes now.
