My local casino rakes 10% up to $5 cap. The 10% rake is twice is what I'm use to playing online (around 5%). On top of that, the BB being 3x the SB is unusual as well. No Solver I know of has the capability to customize rake and odd SB/BB ratios. Most follow the 4-5% online rake structure and solve for bb being 2x the sb.

My question is how do I adjust my preflop ranges for these new parameters? The closest model I have is 1/2 stake with standard 4.5% rake and $2.80 cap. How does the increase rake, extra dollar in the BB, and higher cap affect preflop ranges?

My intuition tells me I have to play significantly tighter preflop, like disgustedly tight. Higher rake requires tighter ranges I know this for a fact, but what about the extra dollar in the BB and higher cap? I think those factors point to playing even tighter but I don't have proof. Does this add up to playing like a super galaxy ultra nit preflop to the point you fall asleep waiting for AA?

Also the preflop raise sizings is baffling, people are raising 5x BB as the standard live. Are they doing this to counteract the higher rake and get more folds preflop? No flop no rake is in effect at my casino, so getting everyone to fold pre seems like a good result. Then it seems that a heavy raise/fold 3bet 4bet preflop strategy to collect dead money and avoid rake is favorable?

With 5x BB raises, you can't raise some marginal 3x BB hands (like small pairs), but I still feel like people are just using regular online preflop ranges and making the sizing bigger live. Isn't this a error for the bottom of your range? For example, hands like 55 being a very marginal small raise becoming -ev when you 5x it. So combine that with the previous paragraph, our raising range has to become even tighter in theory!? Is this really the correct style: playing 15/12 vpip pfr to beat live? Any input appreciated, thx.
