As I have been playing 1/3 and 2/3 NL, I am trying to figure out what is most profitable in regards to raise sizes with particular hands. On one spectrum there is the idea that with hands like QQ+ and AKs, you should raise larger in order to isolate and increase equity. However, there is also the thought of raising smaller to induce more people into the pot and generate more money with premium hands. I agree more in line with the isolation sizing and even if my hands only take the blinds that I should be satisfied with the result. However, with hands that have a lot of potential equity on the flop like suited broadways, suited connectors, suited one gappers, and medium to low pocket pairs, should I be sizing any differently? Thanks for the input!

Don't overthink it. If you only get the blinds and limps, that's fine. If you are at a table where everyone is folding, then start raising way more often and/or raise smaller. If you are getting 6 callers on every raise, then you should raise much bigger, but less often.

Sizing your bets to the strength of your hand is pretty transparent. Either bet the same every time (adjusted for # of limpers), or mix in bigger bets with some non-premium hands. For example, you could also bet big with suited connectors of diamonds.

Lots of discussions and books on this topic. Study up.
