I know there's a lot of naysaying out there about min-raising and why you shouldn't do it, why it's dumb, etc. I was under the impression that min-raising was a sign of weakness / amateurness, but I have put it to use a few times lately with great results. I think min-raising can be used effectively in the right situation. It might even be great to make someone 'think' you're a noob by using it and then BLAM-O! they're out of the tournament.
Ex. I was in BB and caught AA, folded around to the button who raised 3bb. SB folded, I flat called. Flopped trips, checked, he c-bet 1/2 pot, I min-raised, he shoved, I called. I chipped up. I have done this several times recently (not with trips all the time, but similar situations).
Like anything else in poker I think it's very situational and can just be another tool to be used at certain times. Because when you are min-raising you're not looking for the villian to fold. You want a strong hand, strong enough to hope that you can eventually play for stacks if not on this street then later down the road.
Similarly, what about if you yourself are min-raised? You obviously have the odds
to call. But what about if you're on air and someone min-raises you? Do you have to call? It looks super weak if you fold there, and you want to perserve your chips. So what to do? Sacrifice another bet to not look foolish? Would that help down the road to show opponets that you will not fold in such a situation?
