I have read a lot of conflicting views about how one should defend their blinds in NL Hold'em, ranging from the "call moderate raises with everything except 72" to "fold the AQ." Obviously, a lot of it has to do with the opponent, but is defending your blind as effective with people you don't play with regularly, for example online? I can see where defending blinds more aggresivelywith regulars is a winning strat in the long run, but what about in tournaments?Any advice here would be appreciated.
