Was this well played or could I have done something diffrently?

Well besides folding pre-flop is there any flaw? Should I have bet the turn or was the check/raise ok.. just want to know.. and ready to take critisizm(I know spelling).

Preflop: Raise. KJo is not a hand that likes company, so try to eliminate the drawing hands by raising.

Flop: Good bet.

Turn: Aggressive, potentially dangerous, but got the job done.

River: I'm not too happy about this bet. What did you think would happen when you bet 300? Would he fold a pair of queens?

Ty Paulsson..

I'm not too happy about this bet. What did you think would happen when you bet 300? Would he fold a pair of queens?

Fair enough but sorry to answer your question with a question.. but if I didn't bet wouldn't that be a sign of weakness after the bet on the flop then the re-raise on the turn?

In position on the river when it's checked to you, weakness is not a concern. My point is that since it's unlikely he would have folded a pair of queens (or better) your bet had no value. If you had checked, you would have won the same amount anyway, so all your bet achieved was risking more of your chips in case he decided to checkraise you all-in.

That's why I'd advocate a check here. An argument could be made that you want him to pay for the privilege of finding out what hand you were holding, but I don't think that's a very strong reason. You could also have made a smaller value bet, one that would have been called with as little as ace-high, just to take some more of his chips.
