Let's talk about suited connectors.

[Janabis]

I've heard a lot of conflicting views about playing suited connectors preflop, so I want to review my play and see how others are playing them. I find myself frequently open raising with SC's from late position (occasionally reraising with 9Ts or better) and usually folding my small SC's in early position. Basically, I'm hardly ever open limping with them (or any other hand for that matter), but I get the feeling that this is a mistake. My stats are around 18 / 14 and I think this leaves room to widen my range a little. Similarly with hands like Ax suited, I'm usually folding from early position and open raising from late. Should I be widening my range and limping more? What do you do if you're raised from behind? Perhaps folding to a raise when you're heads up oop, but calling with these hands in multiway pots is ok?
