Roy West's "2-point rule" is good for str8 draws. Count cards next to your straight cards as 1 point, cards one away as .5 points. don't play if 2 or more points are out. For example:
you hold 910J and you see a Q (1 pt) and two 7s (.5 each). Fold.

Same hand, you see just one 7 (.5) you like it. If your jack is higher than any other upcard and no one raises, you like it even more.

For small pairs, understand that the only real value is making trips on fourth or hitting an ace or king kicker. So if they are dead, you lose your best potential to win a giant pot in a loose game where many stay in and you make trips/full house. Two small pair is a death hand, and even two big pair ain't great in a loose low limit game where you've got lots of folks drawing and your fullhouse outs are dead.
