This thread is being totally or partly derailed and i can't even tell which. I honestly don't know who's joking and who is not. The only responce that made any sense was basically just quoting a portion of the OP.
I think this is a perfectly legitimate question for a player who is new to online poker.
To OP; where you went wrong was maybe saying that you consider moving to online play similar to dropping limits..thats a bit offensive and probably ill concieved. My bet is that the best players play online if only by sheer number and the idea that online players suck is simply out dated. I thought the same thing when i started playing online again recently after years away (for one thing i'm in the USA so my options have been limited) I digress; this is not 2007, and internet poker is NOT the ATM it was during the poker boom. These kids have become dangerous. Being a 33 year old "old man" myself, I understand all to well the idea you had in your head but I'm telling you now that you need to REALLY pay attention and see if your opponents "unusual" plays are bad plays or if you just don't "get it". I got MY #$$ kicked for a long time until i figured out how to adjust to the new school of online players. To be completely honest, most of my "adjusting" to there strange play was actually intergrating it into my own game.
Another reason your not getting real good advice here is because this topic has been beaten to death. By me for one!
While I still don't use MR's myself, I have dropped my default bttn open to 2.5X; I actually find its best to try different sizings in a single match and adjust from 2.5X. But that's just me.
After thinking this out at length and putting it into practice, and discussing it ALOT on 2+2 I came up with a "Defend vs MinRaise Range" this is based on your opponent opening 100% on the bttn and always MRing. I think it's pretty good and I use this as default myself but I have acutally started calling with some more of the suited connectors and one gappers;
Range vs 100% MR on Bttn HU:22+,A2s+,K2s+,Q5s+,Q7o+,J7s+,T8s+,98s,A2o+,K5o+ ,Q7o+,T9o
I try to 3bet the top half of this range about 75% flat with it 25% and flat call the bottom half about 75% and 3 bet it about 25%
You'll end up with a 25% 3 bet percentage and you'll be defending in some way about 50% (a bit more if you include suited connectors down to 54s)
I tried to PROVE this range mathematically and probably failed but even my critics more or less agreed with my range i think..just denied that i proved it. And, stictly speaking, they were right.
NEway, maybe take a look at the old posts by me on range vs MR, toy game, and others if you can find them. I don't know an easy way but i don't think my "toy game" thread was too long ago. It was essentially about finding a GTO range vs MR.
And welcome to 2+2
