The first bit is about this particular hand. In heads-up play it's correct to open an enormously wide range from the button, because you have an inherent postflop advantage by being in position and you're getting blinded every hand. So when someone opens the button as wide as they're supposed to, if they minraise, then you HAVE to defend with anything that beats his range (adjusting up for pot odds, which are fantastic vs minraise, and then down for postflop disadvantage, which is significant out of position). When someone minraises a standard 70-80%, thus, you have to flat K5o unless you expect Villain to outplay you postflop, because otherwise you're probably defending too tight.
The second bit is general open-raising strategy. When you open raise in a tight dynamic where you will not usually get more than one caller (if everyone at your table is a reg or at least is aware overcalling is bad this will usually happen), so when you open big you're forcing any caller to have a super tight, polarized, all-or-nothing-from-the-beginning range -- against which you have to have the nuts or the near-nuts to continue playing postflop. If you minraise on the other hand, you force them to have a wider postflop range which will miss boards more frequently or get weaker hits, which you thus can take down postflop more frequently. And better yet, if your opponents insist on seeing you with a tight range, that means they're folding to your open a ton, so you're taking a ton of blinds and can easily give up most of the weaker part of your range postflop without losing money (after all, you just need everyone to fold to your open 57% of the time to autoprofit from minraising) -- and you just need villain to fold half the time HU or blind vs blind to do the same).
And, no I'm not Victor Blom, but I'm not exactly afraid of postflop play either.
