I just want to kind of think aloud re PF range stuff, and specifically the concept of 'spreading ranges too thin'. If that even is a concept.......
Specifically, I'm talking about reacting to 3bets. If we fight back, there's only two ways we can do so: 4betting and flatting the 3bet.
Ok situation is: we open BTN, 8% BB 3bettor 3bets us.........
Standard flatting range of 7.8%: 99-66,AQs-ATs,KTs+,QTs+,JTs,T9s,98s,AQo-AJo,KQo
Value 4betting range of 3.0%: JJ+,AKs,AKo
Bluff 4betting range 3.0%: ATs-A8s,A5s-A2s,ATo
This means that when we open 50% of hands OTB, we're folding 72.4% of the time. Slightly more than necessary to stop a 3bet being auto profitable but whatever, we don't expect it to be exploited and if it is then we can do something about it by opening less or whatever.
Now, I've come to hate 4betting with a passion. I never really liked it, and feel that as time has gone on it's become even more of a zero sum game at best. Basically in a vacuum without reads on a player it's really difficult to 4bet bluff, as it only needs a tiny % of a pure bluff range on their part to make a 4bet unprofitable, and is in any case super high variance. (ie, 4betting ATo and getting T9s shoved on you really really sucks).
4betting must've been really useful back when 3betting was just getting a little old. Now, everyone knows that everyone 4bet bluffs etc etc, and I guess my argument mainly is that countering light 4bets is largely solved through appropriate 3bet/5betting, and is thus either reciprocally neutral EV or slightly on the side of the original 3bettor.
Just to ramble some more, I think that we basically all 4bet because everyone else does it, but we all know in our hearts there's no edge there. There's just, no.......... strategy to it, or tricks, or anything deep and meaningful that allows you to have better frequencies or adjust better to than anyone else. We do it just to at least keep pace with everyone else.
So I'm getting out of this game. In fact, I already have. I'm flatting 3bets with all of my continuing range.................
Disadvantages: I can no longer fight back with, say A9o. I don't care though, because as I've already said I think the actual 4bet is bang in the middle of neutral EV, sometimes slightly + EV and sometimes - EV.
Advantages: Really outweight the disadvantages a mon avis. Firstly, I'm playing really big pots, sometimes Ip, with a much stronger range than my opponent. I've won so many 200bb pots this month flatting AA-JJ, even AK VS junky hands like J9 that flop 977 and can't fold.
So that's the advantage in a vacuum. Over the slightly longer term, it should mean I'm able to flat a ton more stuff and be able to bluff more. So, the hands that I lose in fighting back like A9o, I gain in being able to flat 75s and bluff raise with a ton more credibility.
And it's much lower variance (which has other benefits including tilting less, less self doubt etc). And there's a discernable postflop edge. And I don't really see how people are going to exploit it. Answers on a postcard or in this blog, but honestly I'm utterly convinced anyway and I think that more of us just do it because everyone else does, than would care to admit.
Some of these hands might've had the same result to a clean 4bet, but you can clearly see that most of them would've resulted in a PF fold.
Is all, Dan
