No really god read on the opponents but the whole table is pretty passive. (I got kings twice that session and the entire table folded pre-flop.)

No good reads here either except for the table being pretty passive, even checking and calling top pair good kicker from the flop -&gt; river (that cost me some bets [img]/images/graemlins/frown.gif[/img] ).

The thing I'm wondering is when do you throw stuff like this away? Hands where it really seems like your opponent has been helped by the scare card but your hand still looks alright.
