[darkcore]

maybe an easy one, but i'm new to no limit and while playing this hand i was wondering if i played it correct.
what should be my river line?

Raise more PF. Bet pot on the flop. Turn check is ok probably, but bet the river.

I'm new to NL cash games myself, but I make it at least 1.50 PF, and I pot the flop. I am not sure whether or not I'm checking this turn.

[Recliner]

Raise more preflop, any time you raise it should be at least $1. Pot the flop. Check is ok, bet river.

Is there an echo in here?

As played $5 on the river seems good, fold to a raise.
