he needs to call 1bb to hit his set and effective stacks will need to be ~20bb to make his call profitable....therefore his call is always going to be profitable for him. raise him to 4 or 5 bb and he's going to need 80-100 bb effective stacks to break even on the call.

Once he's called he's folding 70% of the time . If he calls that even if you open fold the turn you make a lot more money than min raising pre and half pot cbet

wins( 5bb pre *7 )= 35 bb or min bet is 2bb pre *7= 14bb
loses ((5bb pre +5bb cbet)*3)=30bb (2bbpre+2bb cbet)*3=12bb

net gain 35-30bb =5bb 14-12= 2bb

so you make more when you are called and cbet from raising more preflop and you're less likely to have him calling a raise with his AQ AJ KQ type hands that he wouldn't normally bother with so you can add on some more stolen blinds to the profits.
The call a preflop raise stat tends to sufggest that if this guy can see a flop cheaply with his broadway cards hes going to, and by minraiseing you are letting him do that.
