This range I got it after playing more than 400,000 hands over several years of play in various limits. Despite the time and the evolution of the Limit Hold'em over the years, I still believe that this range applies to many levels. Many times, the game as it is today, this range is void to the extent that the dynamic range of the game and metagame factors make these data almost useless, but this does not contradict the importance of having a range standard with which to operate in principle. If, for example, I am against a very solid player in the blind large, while not broaden my range, it would almost certainly make it as smooth as possible to avoid losing equity. Against a solid player who knows how to think, not want to be in a situation in which the blind can easily estimate the correct equity against my range. While a large part of my default range is basically straight forward, some specific hands deserve brief mention. Small hand Couples (1922-1944) for example, can be difficult to play in many situations post-flop and lose a lot of equity for that.
However, my experience tells me these hands that are profitable on the button against most players. Remember I'm talking about a default range and not something that can be taken for granted and go to church. If your HUD tells you that the blind do not defend themselves with appropriate frequency, then you have to open your range slightly, but even then do not increase in any case more than 5% or 10% maximum.
