Yes with tight players in the blinds is pretty easy just to steal with ATC, until they adjust. Some villains just won't adjust at all. Versus looser people in the blinds you can still steal but just pick hands that are easier to play post flop/have more equity.

I think spoonitnow worked out he math to raise ATC in LP or SB. This assumes ur 0EV postflop.

If you have SB+BB VPIPs equalling less than 15 then its breakeven to raise ATC on the BU.

30 VPIP when ur in SB vs BB

Total 10vpip when in CO vs BU, SB and BB.
