$50, Big Sem-Bluff Early

Preflop fold K-J, it's too weak to play in this relatively early position. Also just call if you are gonna play it for a variety of reasons. On the flop I don't see why not just do a standard continuation bet of ~100 trying to pick the pot up right there. If he calls reavaluate depending on the turn. The way you played it I would just fold after he puts in a solid bet. The checkraise all in isn't a disaster but it commits too many chips for my taste, however if you were feeling it at the time go with it.
