If I'm playing suited connectors, I'm usually only in in 2 situations.
1.) If some has made a small raise or limped and lots of people have called, I will usually call there for the potential for a big flop.
2.) If I'm on the button, I will usually open up here, to try and steal the blinds, and if the blinds called I've got a hand which plays well in position, you can dump if you miss and play it strong if you hit it..
