HU is extremely opponent-dependent but it is definitely a play I (and also more experienced HU players, not like I'm pulling this out of thin air lol) will use. The underlying point of my post though was especially in HU where when you raise you get position the postflop play is so much bigger of a factor than preflop raise size.
Let's go one step further and get specific. If I minraise every hand HU how would my opponent exploit that? Seems the best way would be to call a lot. Now I get to play a ton of pots in position against them.
But basically the point of my post was instead of people saying "this is how you have to play", people should think more about why things happen. Poker is an exploitive game. The way we make money is we make plays that a good opponent could exploit but the bad opponents we are playing against won't be able to exploit. So basically if the extent of someone's logic is "omg minraising is bad and minraisers must suck" instead of thinking about what you are exploiting, how it can be exploited, and how the overall strategy is applied, then I'm pretty sure I could handle them HU even if I would normally raise 3x (although as I mentioned against some opponents I would minraise in HU).
I can see why you'd consider min-raising your pots in position, purely to up the stakes while you're in a spot where you should be winning more of the hands.
But, you're pricing in basically any two cards when you min-raise heads up, so while they've got no idea what you're raising each time, it's always harder to define what they're calling you with as well.
Zachvacs right, minimum raising is definitely a strategy that you can work (HU especially), but you should also know that when you run with this sort of thing you're postflop play has to be spot on. You see pro's like Hellmuth and Negreanu that'll play like this, but their post flop play is generally exceptional. You'll even see Negreanu min-raising multiway pots in tournaments and stuff like that. For your average joe blow playing poker, min-raising a lot can get you into trouble.
