6-max or full-ring? I play twice as many hands in 6-max as I do in full ring games. I will fold alot of hands in a full-ring game that I would play in 6-max.

Here are my full ring selections:
You only have to pay half as much to see the flop but you are totally out of position. If you call with a hand like K10o and flop a king you can't even bet on it like you would in late position. I would limp with pocket pairs 22-99, normally limp with TT unless there is only like one limper and then you would raise, raise with JJ if there are a few limpers, limp with JJ if the whole table has called, raise with AA,KK,QQ, and AK, limp with AQ, KQ, AJ, limp with AT, QJ, KJ, being more likely to limp with few players and if they are suited and depending on the other players, limp with some suited connectors. The exact cards and amount of cards you play with depends on your style and the other players at the table.
