When play has gone to the river and from the way players have bet, noone seems to have a really good hand... if I have a small pair, 2 to 4, or just a high card, 9 to J, ...

... is it better to fold if I think I have a small chance of winning rather than SHOW the other players that I bet to the river with really nothing in my hand...

I did a few searches and scanned through topics to see if I could find an answer, but found nothing...

Thanks!
