Josh Arieh: "Biggest mistake amateurs make"

[darom03]

Josh: "The biggest mistake I see amateurs making is playing big pots out of position. No Limit Hold'em is a positional game and I make it a point to have position when a big pot takes place. For example, say I am in the small blind with AK, I will very rarely raise with this kind of hand here, exclusively because of my position . Yes, the hand is good, but the position out weighs the "ranking value" of the hand. Pot-size management is more important than hand selection in No Limit poker. Work on that and you will become a much better player almost overnight"

Should AK really be checked in the small blind if there are a couple of limpers?

Pot-size management... do any of you know a good site that elaborates on that?
