A lot of people tend to play way too loose in SB with the idea that it costs only half as much. But what I think tends to be forgotten is that you have the worst possible position for the rest of the hand.
Actually, I think I've been playing a bit too loose by including all of my LP hands in the "SB playable for a limp" category.
Specifically, these hands include AXs and suited one-gappers, which are semi-bluff hands for the most part. But, the more I think about this, the more I think the semi-bluff really gets its power with position, which you don't have in SB.
My conclusion: It's probably better to stick with your MP hands to play in SB. Most of these are actually not semi-bluff hands but TP hands like KJo, etc. I think those are the ones you really want to be playing. For me, that would put SB at a VPIP of 16.1%. I don't think that's excessively tight.
Opinions?
