Flop: I've top pair with kicker out of position and a weak straight draw. The flush draw is threatening. Planning to fold, if someone reraises my raise.

Turn: Scary scare card comes. No top pair any more. Betting, because the villains are very loose.

River: Nut Straight against a possible flush. The pot is big, I bet.

Betting a 4 out nut straight draw out of position against an almost done flush may be my great error in this hand. Also, I was strongly out of position. The river bet may also be an error.

What do you think?

Edit: Repaired messed up hand posting.
