The Minimum Raise
Has anybody else noticed, that whenever you make a bet in No Limit Hold'em, and your (weak) opponent raises the minimum, you are nearly always facing the nuts or close to it?
For example, lets say the flop is K-10-10 offsuit, and you bet nearly the size of the pot with A-K. Your opponent raises the minimum. In my experience, you are usually up against at least trip tens and your opponent is sucking you in.
Has anyone else noticed this?
Which leads me to ask:
Can raising the minimum ever be the optimal play (as opposed to calling, folding, or raising some other amount)?
Does anybody ever raise the minimum as a bluff or to get a free card when on a draw?
