I raise minbets on any street if I have middle pair or better, unless villain has shown a tendency to take weird min-bet, min-bet, shove lines with his bluffs in which case I'm calling to try and catch a huge river bluff.

I think the best approach is to come up with a rough approximation of the hands he's willing to minbet postflop, and if he's not running weird multistreet bluffs with odd betsizing on all streets, just keep raising when you're ahead of his minbet range, and fold to pressure if you have a weak one-pair hand.

96% of the time a min-bet is a blocking bet, not some trappy "please raise me!!" bet. The purpose of a blocking bet is what: To get you to call or fold.

What does villain not want us to do the overwhelming majority of the time? Raise. So what is the correct action when donkfish minbets into us, raise! Always strive to make the action that our opponent does not want us to make, because you're either:

1. Denying him/her value when you're beat by folding to bets they want you to calll.
2. Increasing the value of your made hands and bluffs by raising in situations where villain isn't going to exactly be thrilled about putting more chips in (based on board texture)
3. When he wants you to check or call and you bet or raise, you set yourself up to extract value from marginal middling pairs that villain wants to showdown, but not play a big pot with.

Just remember, in general, attacking weakness is a very rarely if ever wrong in NLHE.
