two advices from cardplayer magazine...are they right?

At our limit of play, we more than likely still have a small edge after 4 limpers with KQo. However, this edge is so minute that you should frequently pass on it in order to exploit larger edges postflop. This is true with a lot of hands. I think that's in SSH somewhere but I don't know where.

#2 is a clear indicator of why you need to pay attention to your opponents. Without a fairly large pot I fold here a lot. Though not as frequently as at the higher limits, you are often drawing to 3 outs here. Our limits, however is full of tricky players. It is imperative to know if your opponent will CR here with a hand you beat enough times to make calling profitable.
