Blinds: call unraised pot/check. Only call if the odds are correct; do not get cute!
Early position: fold, unless I am deep stacked in which case I will sometimes raise
Middle position: depends on a number of factors [i.e. how many hands I have been playing, stack size].
Late position: raise and depending on the situation I sometimes re-raise [if it has already been raised] to try and present a big hand.

The important items to remember considering suited connector's are that they are easy to fold if you miss the flop and to carefully consider your odds [and your expected odds for your opponent] post flop before calling, betting, or raising.
